• Dimensions: 49"L x 16"W x 15"H
• Material Type: Polyethylene
• Capacity: 110 liters

Best for: Polaris Ranger long-trip cargo.

Why it ranks #1: Its 110-liter capacity, lockable and waterproof design, and stated fitment for several Ranger 1000 models make it a well-specified bed-storage choice.

The KEMIMOTO 110-liter bed box lists compatibility with multiple Polaris Ranger 1000 and XP 1000 model years, giving those owners a defined starting point for fit selection. Its large capacity accommodates tools, food, or camping equipment, while lockable and waterproof features support organized cargo on longer trips.

The 49-by-16-by-15-inch polyethylene box provides 110 liters of storage, making it suitable for carrying a range of trip supplies in the bed. Its listed Ranger fitment covers Ranger 1000 and Crew 1000 from 2020–2026, XP 1000 from 2018–2026, and Crew XP 1000 from 2019–2026. Lockable closures help secure stored items, and the waterproof feature supports keeping cargo dry.

Skip it if you need a stated Can-Am Defender fit; KEMIMOTO’s KMB0113-17509-BK-M lists compatibility with 2016–2026 Defender models.

This suits owners of the listed Polaris Ranger 1000 and XP 1000 models who need lockable, waterproof space for longer trips. Check the exact model-year range and 49-by-16-inch footprint against the available bed area.

#2 · Best Defender Fit

2. KEMIMOTO Can-Am Defender Bed Box

• Dimensions: 49.6"L x 16.1"W x 15.3"H
• Material Type: Polyethylene
• Capacity: 29 gallons

Best for: Can-Am Defender hunting and work.

Why it ranks #2: This 29-gallon box is specified for 2016–2026 Can-Am Defender models and adds dual-side openings, lockable lids, and six tool or fishing-pole holes.

The KEMIMOTO Defender box combines 29 gallons of capacity with double-side openings, giving users access to long cargo and stored gear from either side. Its fishing-pole bracket holes and lid MOLLE panels add dedicated options for organizing outdoor tools, while the listing specifies compatibility with 2016–2026 Can-Am Defender models.

The 49.6-inch box offers a large, unobstructed 110-liter space for hunting, farming, or trail cargo, and double openings make reaching contents more convenient. Six bracket holes accommodate fishing poles, rakes, or other long tools, while the area between the lids is intended for bait, hooks, and small items. Two MOLLE panels can be attached to the lid for additional organization. The product is listed as lockable and weather-resistant, with no-drilling installation stated in its features.

Skip it if you need a listed fit for a Polaris Ranger; KEMIMOTO’s B0113-17511-BK names Ranger 1000 and XP 1000 model ranges.

Choose this for a listed 2016–2026 Can-Am Defender used for hunting, farming, or trail work, especially when long tools need dedicated placement. Its nearly 50-inch length and Defender-specific fitment are central bed-planning considerations.

#3 · Best Large Capacity

3. KEMIMOTO 110L Cargo Box

• Dimensions: 49.6"L x 16.1"W x 15.4"H
• Material Type: Polyethylene
• Capacity: 110 liters

Best for: Large dual-lid bed organization.

Why it ranks #3: Its 110-liter capacity, dual-lid design, lockable and waterproof features, and removable lid panel suit buyers wanting substantial, configurable cargo storage.

The KEMIMOTO 29-gallon box pairs dual lids with a removable tool panel, letting users organize a large load and reposition the panel for more convenient access. Its 110-liter capacity accommodates items including shovels, spades, and trail-repair tools, while the listed waterproof and lockable features address protection and closure.

The 49.6-inch-long polyethylene box provides substantial bed storage for both small items and longer trail tools. A customizable panel inside the lid can be arranged for tools, then removed and secured to the front of the box with the provided straps, changing where frequently used items sit. Dual lids provide separate access points, and the product is listed as waterproof and lockable. At 40.8 pounds, the box itself is a significant item to account for during installation and bed handling.

Skip it if you want a lighter, smaller side compartment; KEMIMOTO’s 45.3-liter B0113-08001BK is a substantially lower-capacity alternative.

This fits UTV owners carrying a mix of long tools and smaller gear who value a configurable tool panel and dual access. Plan for its 49.6-inch length and 40.8-pound weight when arranging the bed and handling installation.

#4 · Best Included Security

4. StarknightMT UTV Bed Box

• Dimensions: 19"L x 13.36"W x 12.6"H
• Material Type: Polyethylene
• Capacity: 6 gallons

Best for: Polaris Ranger fitment range.

Why it ranks #4: The roughly 6-gallon polyethylene box includes a combination lock and anti-theft rope, with fitment listed for numerous Polaris Ranger and General models.

The StarknightMT bed box lists compatibility across numerous Polaris Ranger and GENERAL models, plus the Massimo T-Boss 550, giving owners a defined fitment range to assess first. Its six-gallon capacity adds enclosed cargo space, while an included combination lock and anti-theft rope address securing the box and its contents.

The listed fitment spans multiple Ranger and GENERAL model families and years, so buyers can compare their vehicle against the stated range rather than relying on a generic UTV claim. Six gallons of polyethylene storage provides room for cargo, and the included combination lock and anti-theft rope offer two stated security-related components. The 19-inch length and 13.36-inch width provide a compact footprint, but the supplied information does not describe a weather seal or waterproof rating.

Skip it if you need a documented waterproof seal; KEMIMOTO’s 29-gallon B0113-17510-BK is listed as waterproof and provides much greater capacity.

Consider this for owners of a specifically listed Ranger, GENERAL, or Massimo model who want compact storage with included security accessories. The stated fitment range is the key boundary, and weather protection is not specified in the supplied details.

#5 · Best Side Storage

5. KEMIMOTO Passenger Side Box

• Dimensions: 27.17"L x 17.13"W x 18.11"H
• Material Type: Polyethylene
• Capacity: 45 liters

Best for: Passenger-side essentials storage.

Why it ranks #5: Its 45.3-liter capacity and water- and dust-resistant sealing offer useful side-bed storage, but buyers must heed its stated model exclusions.

The KEMIMOTO passenger-side box adds 45.3 liters of bed storage for essentials such as gloves, a first-aid kit, straps, and tools, without taking the form of a full-bed trunk. Its rubber sealing strip and dust-resistant construction target protection, while a matching left-side box is offered to pair with it.

This passenger-side compartment measures 27.17 by 17.13 by 18.11 inches, giving buyers dimensions to assess against their bed layout. The 45-liter stated capacity suits organized essentials, and the waterproof rubber strip supports sealing against water and dust. Its polyethylene construction is described as pressure-resistant, with a 100-kilogram maximum weight recommendation. The listing identifies compatibility with 2019–2022 Polaris PRO XD and explicitly excludes Polaris General and Ranger 570 SP, making fitment a key selection check.

Skip it if you own a Polaris General or Ranger 570 SP; KEMIMOTO’s 5.5-gallon KM3B0113-01201BK-CA lists compatibility with Polaris Ranger and General.

This works for buyers needing a passenger-side compartment for organized essentials, particularly owners of a listed 2019–2022 Polaris PRO XD. Its stated exclusions and substantial 18.11-inch height deserve attention when assessing vehicle and bed clearance.

6. KEMIMOTO 82QT Rear Box

• Dimensions: 20.47"L x 11.42"W x 16.93"H
• Material Type: high-quality injection-molded PP material
• Capacity: 82 quarts

Best for: Quick-access rear cargo storage.

Why it ranks #6: The 82-quart rear cargo box uses UV-resistant, water-resistant injection-molded material and dual lockable latches, though specific vehicle fitment is not provided.

The KEMIMOTO 82-quart rear cargo box uses dual lockable latches that open and close quickly, giving riders a convenient way to reach enclosed cargo while securing it afterward. Its injection-molded polypropylene is listed as UV-resistant and water-resistant, making this a defined-capacity option for rear cargo storage.

With 82 quarts of capacity and dimensions of 20.47 by 11.42 by 16.93 inches, the box offers a compact storage volume buyers can compare with available rear space. The high-quality injection-molded polypropylene is described as sturdy, UV-resistant, and water-resistant, supporting outdoor cargo use. Two included anchors provide listed attachment components, while dual lockable latches provide closure and quick access. The supplied information does not specify vehicle model fitment, so the dimensions and mounting arrangement are important considerations.

Skip it if you require stated model-specific fitment; KEMIMOTO’s B0113-17511-BK lists specific Polaris Ranger model ranges and 110-liter capacity.

Choose this for buyers seeking a compact rear box with quick dual-latch access and stated water and UV resistance. Its 82-quart capacity is smaller than 110-liter options, and vehicle fitment must be assessed from its dimensions.

7. Kolpin UTV Saddle Box

• Dimensions: 27"L x 10"W x 15"H
• Material Type: Plastic
• Capacity: 10 gallons

Best for: Lockable inside-rail storage.

Why it ranks #7: This weather-resistant 10-gallon box has lockable latches and mounts to many UTV bed rails, but it explicitly does not fit Polaris Ranger or RZR models.

The Kolpin Saddle Storage Box mounts to the inside bed rails of most utility vehicles, placing 10 gallons of weather-resistant storage along the bed rather than claiming a universal fit. Lockable latches help secure tools or rain gear, while the rear-hinged lid provides access from the mounted box.

Its 1.375-cubic-foot capacity and 27-by-10-by-15-inch dimensions give buyers a defined storage footprint for tools, rope, or rain gear. The weather-resistant plastic construction helps protect those items, and stainless-steel mounting hardware is included for installation on inside bed rails. Lockable latches add a security measure, while the rear-hinged lid controls the access direction. Fit is a decisive limitation: the listing says it does not fit Polaris Ranger or Polaris RZR models.

Skip it if you own a Polaris Ranger or RZR; KEMIMOTO’s 5.5-gallon KM3B0113-01201BK-CA is listed as compatible with Polaris Ranger and General.

This is for utility-vehicle owners seeking lockable, inside-rail storage for tools and rain gear, provided their vehicle is outside the stated Polaris exclusions. Its 27-inch length and rear-hinged lid also matter when planning bed access.

#8

8. KEMIMOTO 5.5-Gallon Bed Box

• Dimensions: 8.6"L x 18"W x 13"H
• Material Type: Polyethylene (PE)
• Capacity: 75 kg

Best for: Compact bed-side organization.

Why it ranks #8: A compact 5.5-gallon polyethylene box with a waterproof rubber ring and stated 75-kilogram load capacity suits smaller essentials rather than bulky cargo.

The KEMIMOTO 5.5-gallon box can sit on either the left or right side of a UTV bed, leaving buyers flexibility to organize smaller essentials around other cargo. Its rubber-ring seal and restrained-opening lid target weather protection and controlled access for snacks, tools, or gloves on trips.

At 21 liters, this box is sized for everyday small cargo rather than a large haul, while its stated 75-kilogram load capacity gives a useful load limit to consider. The waterproof rubber ring supports a sealed closure, and the lid’s limited opening angle helps prevent the lid from falling open. Its 18-inch length and side-placement options can help preserve open bed area, though the supplied compatibility information names Polaris Ranger and General models without a year range.

Skip it if you need a 29-gallon cargo box for long tools or larger loads; KEMIMOTO’s B0113-17510-BK provides substantially more stated capacity.

This suits SXS owners who want a small, side-positioned compartment for trip essentials while keeping some bed space open. Check the specific vehicle compatibility and allow for its 18-inch length before settling on a mounting position.

#9

9. Kolpin Rear Trail Box

• Dimensions: 37"L x 17.5"W x 13.5"H
• Material Type: Polyethylene (PE)

Best for: Helmet-carrying trail riders.

Why it ranks #9: The 37-inch rotomolded box fits up to two XL helmets and has weather sealing, but its rear-rack design is less directly suited to UTV bed cargo.

The Kolpin Rear Trail Box fits up to two XL-sized helmets while retaining extra storage room, making it a practical rear-rack choice for riders carrying headgear between outings. Its contoured shape makes use of rack space, and the lockable lid helps keep stored equipment secured during transport.

A double-wall lid adds rigidity and supports the optional accessory rack, giving buyers a way to add that separate rack without relying on a single-layer lid. The roto-moulded, UV-stabilized polyethylene construction is suited to outdoor use, while automotive-style weather sealing helps keep gear dry. Included U-bolt mounting hardware provides the components for attachment. At 37 inches long, the box occupies substantial rack space, so check the available rear-rack area before choosing it.

Skip it if you need a bed-mounted box rather than a rear-rack helmet carrier; KEMIMOTO’s 29-gallon B0113-17510-BK offers much larger stated capacity.

Choose the Kolpin for ATV riders who want lockable helmet storage and weather-sealed gear space on a rear rack. Its 37-inch length and optional, separately sold accessory rack are important considerations for available rack space and setup.

#10

10. Fsehyue Aluminum Rear Box

• Dimensions: 35.5"L x 18.5"W x 6.5"H
• Material Type: Aluminum

Best for: Shallow aluminum tool storage.

Why it ranks #10: This lockable aluminum box measures 35.5 by 18.5 by 6.5 inches, but its shallow profile and limited UTV-specific fitment details make it a less certain cargo choice.

This Fsehyue rear box uses gas springs on both sides to support its lid, a useful distinction when opening a shallow aluminum compartment for maintenance tools or rope. Its 35.5-inch length provides a broad storage footprint, while the latch and keys offer a lockable closure for ATV, UTV, truck-bed, or trailer use.

The aluminum construction and tread-pattern exterior provide a metal storage option for off-road vehicles, utility vehicles, truck beds, and trailers. At 35.5 by 18.5 by 6.5 inches in the specifications, it has a notably shallow profile suited to items that fit within that height. Gas springs on both sides provide stable elastic lid support, while the latch and keys allow the box to be locked. Measure the available space and cargo height against those dimensions before installation.

Skip it if you need a 29-gallon enclosed bed box for bulky gear; KEMIMOTO’s B0113-17510-BK lists 110 liters of capacity.

This suits buyers wanting a shallow, lockable metal compartment for tools or other low-profile cargo across vehicle and trailer settings. Its 6.5-inch height is the practical boundary, so taller equipment calls for a deeper storage solution.
