Here's the thing about UTV storage: the box that fits your neighbor's Ranger will not bolt into your Maverick X3, and no amount of wishing changes that. Fitment is the first filter, capacity is the second, and everything else — seals, latches, lid material — is the tiebreaker.
This roundup reads the published specifications for ten UTV and side-by-side cargo boxes and sorts them by what they actually claim to do. Capacities in the group run from a 20L removable bed box all the way to a 45-gallon rear bed box. Mounting styles range from tool-free quick pegs to a 60-inch aluminum chest with gas struts.
Nobody on this website has installed, loaded or hauled any of these boxes. What follows is a close reading of manufacturer and retailer listing data, plus the practical conclusions that data supports for a buyer choosing between them.
Quick Comparison Table
| Product | Best For | Sealing Claim | Locking | Price |
|---|---|---|---|---|
| Rough Country Rear Bed Cargo Box for Can-Am Maverick X3 (2 & 4-Seat | Maximum published volume | Sealed, water-tight and dustproof | Padlock-ready latches | |
| KEMIMOTO UTV 82QT Rear Cargo Storage Box Water Resistant Replace | Late-model RZR XP 1000 | Waterproof and dust-proof, water-resistant | Lockable latches | |
| Kolpin UTV Metal Bed Box | Metal construction | Gasketed/weatherproof lid | Lockable stainless steel latches, both sides | |
| KEMIMOTO UTV Bed Storage Box Compatible with 2016-2026 Can-Am Defender | Seller-stated IP67 level | IP67 waterproof level (seller claim) | Not stated in the supplied listing | |
| KEMIMOTO UTV Bed Storage Box 5.5GAL Compatible with Polaris Ranger | Small tool-free side box | Waterproof rubber ring | Combination lock and wire rope |
What to Look For in a UTV Cargo Box
Buying a side-by-side box is mostly an exercise in narrowing, in this order:
- Fitment first, always. Most of these boxes publish a specific compatibility list, and those lists barely overlap. A Can-Am Defender box and a Polaris RZR box are not interchangeable, and several listings explicitly ask you to confirm your model year before ordering.
- Capacity in the units you can picture. These listings mix liters, gallons and quarts. Rough Country publishes 45 gallons; KEMIMOTO publishes 110L/29Gal, 82QT, 69QT, 28L and 21L/5.5GAL. Convert before you compare.
- What the seal claim actually says. "Waterproof" on a marketing bullet is a seller's claim. Some listings state a standard-referenced level — the KEMIMOTO UTV Bed Storage Box Compatible with 2016-2026 Can-Am Defender lists an IP67 waterproof level — which is a more specific kind of seller statement than "waterproof lid design," though it is still the seller's own published claim rather than an independently verified test result.
- How it locks, and whether a lock is included. Some listings specify padlock-ready latches, some a combination lock and wire rope, some keys in the box, and some say nothing about locking at all.
- Mounting method and removability. Quick pegs, pins, a knob, or a quick-release mechanism — each trades install speed against how permanent the setup feels. The supplied listing for the Kolpin UTV Metal Bed Box does not state a mounting method at all.
- Whether the lid stays out of your way. A 60-inch chest that opens 90 degrees on gas struts behaves very differently in a loaded bed than a small hinged lid.
The Best UTV Cargo Storage Boxes in 2026
Rough Country Rear Bed Cargo Box for Can-Am Maverick X3 (2 & 4-Seat Models) — Best for Maverick X3 owners hauling full camp loads
This is the volume leader among the boxes reviewed here on published figures: Rough Country lists a 45-gallon capacity across a 44" x 23.3" x 10.2" storage area, which the brand frames as room for tools, recovery straps and camping gear. That 10.2-inch depth is the number to sit with. It is a wide, shallow footprint — great for laying out straps, jacks and soft bags, less suited to anything tall standing upright.
The fitment is narrow on purpose. Rough Country states it is engineered specifically for the Can-Am Maverick X3 in 2-seat and 4-seat configurations, so cross-shopping it for a Ranger or a Defender is a non-starter. In exchange you get a custom-fit part rather than a universal bin wedged into a bed.
On protection, the listing describes a sealed, water-tight design that blocks rain, mud and dust, plus high-impact UV-resistant construction and a scratch-resistant finish. Security is padlock-ready latches — meaning you supply the padlock. The quick-release mounting is described as tool-free for install and removal, which matters if you swap between a loaded weekend rig and an empty bed for work. Rough Country backs it with a Limited Lifetime warranty, which is the most substantial warranty statement in this entire group.
Pros
- Largest published capacity here at 45 gallons
- Exact dimensions published: 44" x 23.3" x 10.2"
- Tool-free quick-release mounting for fast removal
- Padlock-ready latches and a scratch-resistant finish
- Limited Lifetime warranty stated by the manufacturer
- Fits only the Can-Am Maverick X3 2-seat and 4-seat models — no cross-platform use
- Padlock is not described as included
- The 10.2-inch depth limits tall items despite the large overall volume
KEMIMOTO UTV 82QT Rear Cargo Storage Box Water Resistant Replace #2889611 — Best for 2024-2026 Polaris RZR XP 1000 rear beds
That's the highest stated load figure among the boxes in this roundup that publish one, and it suggests the lid can take a rider sitting on it or a cooler stacked on top without the structure being the weak link. Treat that as an inference from the published number, not a demonstrated result.
Fitment is tight and recent: the KEMIMOTO UTV 82QT Rear Cargo Storage Box Water Resistant Replace #2889611 (B0D57YRT48) is listed as compatible with 2024, 2025 and 2026 Polaris RZR XP 1000 and 4 1000 in Ultimate, Sport and Premium trims. The brand describes a trapezoidal shape, wider at the top and narrower at the bottom, to maximize volume while fitting the XP 1000 rear without interference. That's a design decision aimed at one bed, and it explains why the capacity number lands where it does.
Installation is quoted at under five minutes: drop the box into the SXS rear bed and secure it with two locks, no tools. It also comes off easily for drainage and cleaning, and KEMIMOTO says a dirty box can simply be rinsed with water. Lockable latches plus a reinforced waterproof sealing structure handle security and weather. Note the listing's own hedging — it is titled water-resistant while the bullets say waterproof and dust-proof, so plan accordingly rather than treating it as a submersion rating.
Pros
- Manufacturer states a weight capacity up to 220 lbs
- UV-resistant PP construction rated by the seller for extreme temperature swings
- Lockable latches with a reinforced waterproof sealing structure
- Tool-free install quoted at under five minutes
- Compatibility is limited to 2024/2025/2026 RZR XP 1000 and 4 1000 variants
- The listing mixes "water-resistant" and "waterproof" language, so the sealing claim is not a rated figure
KEMIMOTO UTV Cargo Storage Box 110L/29Gal, Large Capacity Box Waterproof — Best for CFMOTO Uforce owners carrying long-handled tools
At 110 liters (29 gallons), this is the biggest KEMIMOTO box in the group, and the listing makes a specific claim most storage boxes don't: it can accommodate shovels, spades and trail repair tools. That's a shape claim as much as a volume claim. If your problem is that a shovel handle won't fit in anything you've tried, that bullet is the one to read twice.
The organization feature is genuinely uncommon among the listings here. Inside the lid there's a panel you can arrange tools on, and you can remove that panel and strap it to the front of the box using the provided straps for quicker access to whatever you reach for constantly. It's a small thing that suggests the designers thought about a working rig rather than a weekend cooler.
Fitment is CFMOTO-only: the KEMIMOTO UTV Cargo Storage Box 110L/29Gal (B0D1QQM7FM) lists Uforce 1000 for 2019-2025, Uforce 1000XL for 2022-2026, and Uforce U10 Pro and U10 XL Pro for 2025-2026. All installation hardware is included, so no separate parts run. Security is a lockable rear cargo box that comes with keys — a real advantage over padlock-ready designs where you supply your own. Construction is polyethylene with a waterproof lid design.
Pros
- 110L / 29-gallon capacity, the largest KEMIMOTO box in this lineup
- Explicitly sized for shovels, spades and trail repair tools
- Removable in-lid tool panel that straps to the front of the box
- Comes with keys, so locking hardware is included
- All installation hardware included
- CFMOTO Uforce fitment only — no Polaris or Can-Am compatibility listed
- Exterior dimensions are not stated in the supplied listing information
Kolpin UTV Metal Bed Box — Best for work rigs that want an aluminum chest with both-side access
This one is 15-gauge diamond plate aluminum, and that material choice drives everything else about it. Metal construction with a reinforced sub-frame and a full-length piano hinge is a different durability proposition than the injection-molded polyethylene several other boxes here publish — Kolpin specifically credits the sub-frame and hinge with increased rigidity.
The published dimensions tell you the intended use immediately: 11" (H) x 12" (W) x 60" (L). That's a long, narrow chest, not a bin. Sixty inches means it's designed to span the front of a bed rather than sit in a corner, and Kolpin notes it opens fully when positioned at the front of the bed without interfering with the cab. Two gas shocks hold it at 90 degrees, so the lid stays put while you're digging through it with both hands full.
Security is the standout detail. Lockable stainless steel latches are accessible from both the driver and passenger sides, which means you're not walking around the machine to open it. The lid is gasketed and described as weatherproof. One thing to be clear about: the supplied listing information does not state a capacity in gallons or liters, does not state a load rating, and does not publish a vehicle-specific fitment list, so measure your bed against those 60 inches before you commit.
Pros
- 15-gauge diamond plate aluminum construction
- Lockable stainless steel latches reachable from both sides of the machine
- Two gas shocks hold the lid at 90 degrees, hands-free
- Full-length piano hinge and reinforced sub-frame for rigidity
- Gasketed weatherproof lid
- At 60 inches long it demands a bed that can accommodate it — check before buying
- The supplied listing does not state a volume capacity or a weight rating
- No vehicle-specific compatibility list is given in the supplied listing information
KEMIMOTO UTV Bed Storage Box Compatible with 2016-2026 Can-Am Defender — Best for Defender owners who want a seller-stated IP67 figure
This one earns its spot on a single specification: KEMIMOTO publishes an IP67 waterproof level alongside a rubber strip design for the KEMIMOTO UTV Bed Storage Box Compatible with 2016-2026 Can-Am Defender. The other listings in this roundup say "waterproof" or "water-tight" as a descriptive claim; IP67 is a standard-referenced statement about dust and water ingress, which is a more specific thing for a seller to put in writing. Worth noting it is the seller publishing it, not an independent verification.
Capacity is 28L, aimed at snacks, tools and gloves under a heavy-duty lid. This is a bed organizer, not a haul-everything chest — the pitch is keeping your bed tidy and reducing clutter rather than replacing bed space. If you're loading firewood or coolers, look at the bigger boxes above.
The compatibility range is broad for a model-specific part: all Can-Am Defender and Defender Max models from 2016 through 2026, covering HD5, HD7, HD8, HD9, HD10 and the Max HD7 through HD10 variants, plus Can-Am Commander and Commander Max 2021-2025 in 1000R, 700, Max 1000R and Max 700. Installation comes with clear instructions and the brand says the box stays securely in place on rough terrain. It's removable, which helps for cleaning.
Pros
- Seller publishes an IP67 waterproof level for this box
- 28L under a heavy-duty lid
- Covers Defender and Defender Max 2016-2026 across HD5 through HD10
- Also listed for Commander and Commander Max 2021-2025
- Removable design for cleaning
- 28L is modest next to the 45-gallon and 110L boxes here
- The supplied listing does not state a lock, a weight rating, or exterior dimensions
KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 — Best for RZR owners who want volume and a broad listed fitment
Sixty-nine quarts of injection-molded, UV-resistant polyethylene, with a waterproof seal — that's the core of this box. KEMIMOTO positions it as a rear bed tool box that leaves room in the bed for other bags and coolers, which is a useful distinction. It's meant to coexist with the rest of your load, not consume the whole bed.
The fitment list is the widest RZR coverage in this roundup: RZR XP 1000, XP Turbo, XP Turbo S, Turbo S, S 900, 900 and S 1000 in 2-seater or 4-seater form, plus 2024-2025 and 2021-2022 RZR Trail S 900 Sport and RZR Trail S 1000 Ultimate. KEMIMOTO does direct buyers to the details page for specific models, which is a fair signal that you should verify rather than assume.
Install is quoted at under five minutes with no additional tools or hardware: slide the box into the SXS and into the two rear slots, then install two locks. It disassembles easily for drainage and cleaning. The listing does not state a weight capacity or exterior dimensions, so if you're planning to sit on it or stack on it, that data isn't in the supplied information.
Pros
- Broadest RZR fitment list here, including Turbo, Turbo S and Trail S variants
- Injection-molded UV-resistant polyethylene with an integrated waterproof seal
- Under-five-minute, no-tools install; easy to disassemble for cleaning
- No weight capacity or exterior dimensions in the supplied listing information
- The listing directs you to the details page for specific model confirmation
KEMIMOTO UTV Bed Storage Box 5.5GAL Compatible with Polaris Ranger General — Best for a compact, lockable side box on a Ranger or General
This is the small, flexible one. At 21L/5.5GAL it holds snacks, tools and gloves, and KEMIMOTO notes it can be mounted on either the left or the right side — so you can put it where it doesn't fight the rest of your bed layout. That placement flexibility is the practical selling point, not the volume.
The lid is textured black LDPE, and KEMIMOTO states the box can withstand 75kg (roughly 165 lbs) with improved leak and pressure resistance. The brand also describes a design detail worth understanding: the opening angle is limited within a certain range, and the lid design prevents the box from falling. Combined with the waterproof rubber ring seal, that's a lid that's meant to stay controlled rather than flop open on a slope.
Security is handled by a combination lock and wire rope, so there's no key to lose — a genuinely different approach from the keyed and padlock-ready boxes here. Installation uses quick mount pegs and needs no tools or extra hardware. Fitment covers Polaris General 1000 and Ranger 500, 570, 900 and 1000 including XP models across 2016 through 2026, plus the Massimo T Boss 550.
Pros
- Mounts on either the left or right side for layout flexibility
- Manufacturer states it withstands 75kg
- Combination lock and wire rope included — no keys to misplace
- Waterproof rubber ring seal and a controlled lid opening angle
- Wide Ranger/General fitment from 2016 through 2026, plus Massimo T Boss 550
- 21L/5.5GAL is the small end of this lineup — supplementary storage, not primary
- Lid material is LDPE, a softer polyethylene than the injection-molded PP used on some larger boxes here
StarknightMT UTV Bed Storage Box 6.34 GAL Compatible with Polaris Ranger — Best for Ranger owners who want a box that doubles as a seat
StarknightMT publishes 24L (6.34GAL) here, which is slightly more than the 21L KEMIMOTO Ranger box it competes with directly. The more interesting bullet is the dual-use claim: the brand says the load-bearing capacity lets the box serve as a chair and a footrest, giving you a clean place to sit outdoors or a step for reaching higher. Note that StarknightMT describes this capability without publishing a numeric weight rating in the supplied listing, so it's a manufacturer claim rather than a figure you can compare against the 75kg and 220 lb numbers elsewhere in this roundup.
Construction is PE with a sealed rubber strip inside, which StarknightMT says prevents water penetration and keeps the interior dry. Security is an anti-theft lock plus a spring rope — a similar approach to the tethered-lock design used on other small bed boxes here.
Installation uses three quick mount pegs and is tool-free. Fitment runs 2016-2026 across Polaris Ranger and Ranger XP 1000, 900, 570 and 500, plus General 1000 for the same years and the Massimo T Boss 550. StarknightMT opens its own fitment bullet by asking you to confirm your model and production year before ordering, which is sensible advice for a ten-model-year compatibility span.
Pros
- 24L (6.34GAL), slightly larger than the comparable 21L Ranger box here
- Manufacturer says it works as a chair and footrest as well as storage
- Sealed rubber strip inside a PE shell to prevent water penetration
- Anti-theft lock with spring rope included
- Tool-free install using three quick mount pegs
- No numeric weight rating in the supplied listing to back the seat/footrest claim
- Exterior dimensions are not stated in the supplied listing information
XATVXUTV 21L UTV Cargo Storage Box for Polaris Ranger 1000 900 — Best for Polaris owners who want a built-in small-parts tray
The differentiator here isn't the 21L capacity — it's the tool tray. XATVXUTV builds a tray into this box specifically for the small stuff that disappears in a deep bin: screwdrivers, sunglasses, band-aids. If you've ever dug through a cargo box for a single hex key, you understand why a divided tray earns its keep.
The shell is high-strength polypropylene, which XATVXUTV describes as sealed and waterproof against dirt, snow and rain. Two strong latches hold it closed, and the brand's claim is that this keeps the box stable on rough terrain without spills or shifting. That's a latch-driven stability argument rather than a mounting-driven one, which is worth noting.
Installation is three pins into existing holes in the UTV bed, with all mount hardware in the package. Fitment is the broadest Polaris list among the small boxes here: General 1000, General 4 1000, General XP 1000 and General XP 4 1000 for 2016-2025, Ranger and Ranger XP in 1000, 900, 570 and 500 including Crew models for 2016-2025, and — unusually — CFMOTO Uforce 500 and 800 as well. That CFMOTO crossover makes it one of the few small boxes here spanning two brands.
Pros
- Integrated tool tray for screwdrivers, sunglasses and other small items
- High-strength polypropylene with a sealed, waterproof design
- Two strong latches to keep the box closed over rough ground
- Fits Polaris General, Ranger and Ranger XP 2016-2025 plus CFMOTO Uforce 500/800
- Three-pin install with all mount hardware included
- The supplied listing does not state a lock or locking hardware — the latches are described as strong, not lockable
- No weight rating or exterior dimensions in the supplied listing information
- Polaris fitment is listed through 2025
XATVXUTV 20L Removable UTV Cargo Storage Box for Can-Am Defender/Commander — Best for Defender owners who want a tray-equipped box that pops out fast
The Can-Am sibling to the box above, at 20L, with the same tool tray for screwdrivers, sunglasses and band-aids. XATVXUTV describes it as a double layer cargo box, which lines up with the tray-over-main-compartment arrangement. Same high-strength polypropylene, same sealed waterproof engineering against dust, snow and rainwater.
The mounting is the notable difference from its Polaris counterpart. Instead of pins, you align the box with the holes in the rear cargo bed and turn a knob located beneath the tool tray to secure it. That's a genuinely fast removal path if you pull the box out at the end of every ride — no tools, no fumbling underneath the box.
For the XATVXUTV 20L Removable UTV Cargo Storage Box for Can-Am Defender/Commander (B0F4D9R6TY), fitment covers Can-Am Defender HD5, HD8, HD10, Max HD8 and Max HD10 for 2016-2025, plus Can-Am Commander for 2021-2025. Note that the Defender list here skips HD7 and HD9, which the 28L KEMIMOTO Defender box does include, so check your specific trim. Two strong latches hold the lid closed on rough terrain.
Pros
- 20L with an integrated tool tray in a double layer design
- Knob-secured mounting under the tray for genuinely quick removal
- High-strength polypropylene with sealed, dustproof and waterproof engineering
- Two strong latches for stability over rough ground
- Covers Defender and Defender Max 2016-2025 plus Commander 2021-2025
- Smallest published capacity in this roundup at 20L
- The supplied Defender fitment list names HD5, HD8, HD10, Max HD8 and Max HD10 — HD7 and HD9 are not listed
- No lock, weight rating or exterior dimensions stated in the supplied listing information
How We Research
This website does not perform hands-on testing, and no one here has installed, loaded or ridden with any of these boxes. Our process for this page was documentary: we pulled the Amazon Creators API verified product record for each of the ten ASINs on September 6, 2026, then read every product listing feature bullet on each of those records line by line.
From there the work is comparison and interpretation. We converted published capacities into common units so a 69QT box and a 45-gallon box could be ranked against each other, separated seller-published numeric figures (an IP67 level, a 220 lb weight capacity, a 75kg load) from descriptive marketing language ("waterproof lid design"), and mapped each fitment list against the others to identify where a buyer actually has a choice and where they don't.
Where a listing is silent — no dimensions, no weight rating, no lock specified — we say so rather than guessing. A blank field means the supplied listing information didn't include it, not that the manufacturer never publishes it somewhere else.
Frequently Asked Questions
No — treat these as separate parts. The RZR-fitment boxes in this roundup list RZR XP 1000, XP Turbo, Turbo S, S 900 and S 1000 variants, while the Ranger-fitment boxes list Ranger 500, 570, 900 and 1000 plus General 1000. Those lists do not overlap, and several of the listings ask you to confirm your model and production year before ordering.
What is the largest UTV cargo box here?
By published figures it's the Rough Country Rear Bed Cargo Box for Can-Am Maverick X3 at 45 gallons over a 44" x 23.3" x 10.2" area. The KEMIMOTO UTV Cargo Storage Box 110L/29Gal is next at 29 gallons, followed by the KEMIMOTO UTV 82QT Rear Cargo Storage Box at 82 quarts, which is roughly 20.5 gallons.
Which of these boxes actually lock?
The locking descriptions vary a lot. Rough Country specifies padlock-ready latches, the KEMIMOTO 110L box comes with keys, the KEMIMOTO 82QT box has lockable latches, the Kolpin has lockable stainless steel latches on both sides, the KEMIMOTO 5.5GAL box includes a combination lock and wire rope, and the StarknightMT includes an anti-theft lock with spring rope. The two XATVXUTV boxes describe strong latches but no lock in the supplied listing information.
Are these boxes genuinely waterproof?
All of these sealing claims come from the sellers' own listings, and none of the supplied records include an independent test. KEMIMOTO states an IP67 waterproof level for the KEMIMOTO UTV Bed Storage Box Compatible with 2016-2026 Can-Am Defender, which cites a standard but is still the seller's published claim. Other listings use descriptive wording — "watertight seal," "waterproof rubber ring," "sealed and waterproof design." Note that the KEMIMOTO 82QT box is titled water-resistant even though its bullets say waterproof, so plan for weather rather than submersion.
How much weight can a UTV storage box hold?
Only some of these publish a number. KEMIMOTO rates the 82QT RZR box at up to 220 lbs and the 5.5GAL Ranger box at 75kg. Rough Country, Kolpin, StarknightMT and XATVXUTV do not state a weight capacity in the supplied listing information for their boxes here, so don't assume a sit-on-it rating you can't read.
Do any of these need drilling or tools to install?
Not among the ones that describe their install. The KEMIMOTO 69QT and 82QT boxes are both quoted at under five minutes with no tools, Rough Country uses a tool-free quick-release mechanism, the KEMIMOTO 5.5GAL and StarknightMT boxes use tool-free quick mount pegs, the XATVXUTV Polaris box uses three pins into existing bed holes, and the XATVXUTV Can-Am box secures with a knob under the tool tray.
What's the advantage of a metal UTV bed box?
The Kolpin UTV Metal Bed Box is the only listing here that states aluminum construction, built from 15-gauge diamond plate with a reinforced sub-frame and a full-length piano hinge that Kolpin credits with increased rigidity. Its listing also describes two features the other supplied listings do not mention: gas shocks holding the lid at 90 degrees, and lockable latches you can reach from both the driver and passenger sides.
Final Verdict
If you own a Can-Am Maverick X3, stop reading and buy the Rough Country Rear Bed Cargo Box for Can-Am Maverick X3. Nothing else in this group combines a 45-gallon capacity, published dimensions, padlock-ready latches and a Limited Lifetime warranty for a single machine. Check Price on Amazon
For a 2024-2026 RZR XP 1000, the KEMIMOTO UTV 82QT Rear Cargo Storage Box Water Resistant Replace #2889611 is the sharper answer, because its 220 lb published weight capacity and trapezoidal shape are engineered around that exact rear bed. Turbo-variant and Trail S RZR owners should check the KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 instead, and confirm their model and year against its listed fitment. Check Price on Amazon
Can-Am Defender owners face a real choice. Take the KEMIMOTO UTV Bed Storage Box Compatible with 2016-2026 Can-Am Defender at 28L if the seller-published IP67 waterproof level is what you care about. Take the XATVXUTV 20L Removable UTV Cargo Storage Box for Can-Am Defender/Commander if you'd rather have the built-in tool tray and knob-release removal, and your trim appears on its HD5/HD8/HD10 list. Check Price on Amazon
CFMOTO Uforce owners should look at the KEMIMOTO UTV Cargo Storage Box 110L/29Gal, with a removable in-lid tool panel and 29 gallons that the listing says will swallow shovels and spades; its fitment bullet lists Uforce 1000, 1000XL, U10 Pro and U10 XL Pro. If you run a Uforce 500 or 800, the XATVXUTV 21L UTV Cargo Storage Box for Polaris Ranger 1000 900 lists those machines on its own fitment bullet.
And if you want a metal box, the Kolpin UTV Metal Bed Box is the only listing here that states one — 15-gauge diamond plate, gas-strut lid, stainless latches on both sides. Just confirm your bed can take 60 inches of length first.

Sources & Methodology
Nothing on this page came from a garage, a trail or a lab — this website did not physically or laboratory-test any of these cargo boxes, and it does not run hands-on testing of any kind. What informed these picks is the Amazon Creators API verified product record for each of the ten ASINs, retrieved on September 6, 2026, along with every product listing feature bullet published on those records; the analysis is a close comparison of what those manufacturers and sellers put in writing about capacity, materials, sealing, locking, mounting and vehicle fitment.
For UTV storage specifically, that documentary approach carries you further than it would in most categories, because the buying decision is dominated by two things a spec sheet states outright: whether the box fits your exact machine and model year, and how much it holds. It tells you less about long-term durability, seal aging or how a latch behaves after two seasons of mud, so weigh the warranty terms and current owner feedback on the listing itself before you commit.
