Best Fender Well Tool Boxes For Trucks: Compare 10 Options

#1 · Best Overall

1. UWS EC30012 Driver-Side

• Weight: 41 lb
• Material: Aluminum

Best for: Driver-side drawer organization.

Why it ranks #1: Its heavy-wall aluminum 48-inch design includes three rear-facing drawers, a RigidCore lid, and a MicroSeal gasket for organized, protected wheel-well storage.

Three rear-facing sliding drawers distinguish this 48-inch UWS driver-side box, separating small tools from the rest of the stored gear. The drawers lock behind a rear door, while the wheel-well design puts storage into otherwise used bed space and leaves room for other cargo.

The drawer set includes one 3-by-43⁄8-by-15-inch compartment and two measuring 2 by 43⁄8 by 15 inches, giving small items dedicated places rather than a shared pile. A RigidCore foam-filled lid and extra-thick, one-piece aluminum support a durable box, while the MicroSeal gasket helps keep dust, debris, and moisture out. Its 3.9-cubic-foot capacity and driver-side orientation are listed; mounting hardware is not included.

Skip it if you need passenger-side drawer storage; UWS EC30032 offers the same listed three-drawer arrangement on that side.

This suits drivers who want sorted tool storage on the truck’s driver side without giving up wheel-well bed space. Review the 48-inch dimensions and source mounting hardware separately before installation.

#2 · Best Drawer Storage

2. UWS EC30032 Passenger-Side

• Dimensions: 48 x 8.75 x 24.63 in
• Weight: 41 lb

Best for: Organized passenger-side work gear.

Why it ranks #2: This passenger-side aluminum box offers three integrated rear-facing drawers behind a rear door, plus a RigidCore lid and MicroSeal gasket.

Three rear-facing sliding drawers set this 48-inch UWS apart, giving small tools their own compartments instead of leaving everything in one open storage area. The passenger-side box integrates with the truck’s wheel well, making use of bed space while keeping the drawers secured behind a rear door.

The three drawers—one measuring 3 by 43⁄8 by 15 inches and two measuring 2 by 43⁄8 by 15 inches—offer separated places for smaller equipment, so frequently used items can be sorted by task. A RigidCore lid and one-piece, extra-thick aluminum construction support a sturdy storage setup, while the MicroSeal gasket helps keep dust, debris, and moisture away from contents. Its 48-inch passenger-side format uses wheel-well space; mounting hardware is not included.

Skip it if you need a box with mounting hardware included; Dee Zee DZ 95D lists mounting hardware and a quick-release bracket.

This suits truck owners who want compartmentalized hand-tool storage on the passenger side while retaining wheel-well bed space. Check the 48-inch dimensions and plan to source mounting hardware separately before installation.

• Dimensions: 46.63"L x 15.43"W x 16.4"H
• Material: Aluminum

Best for: Driver-side fleet key management.

Why it ranks #3: The driver-side aluminum box lists 3.4 cubic feet of storage, a full weather seal, and an automotive-grade lock-and-latch system.

Weather Guard’s coded key system lets an owner manage one box or coordinate keys across a fleet, making this driver-side model particularly relevant to work trucks. Its 3.4-cubic-foot aluminum compartment also has a full weather seal and an automotive-grade lock-and-latch system.

The 46.63-by-15.43-by-16.4-inch box uses wheel-well space above and behind the wheel, adding storage without claiming a particular vehicle fit. A full weather seal helps protect contents from the elements, while the picking-resistant lock-and-latch system addresses access security. The coded-key feature can simplify handling when the same owner manages multiple truck boxes. Its aluminum construction and ARMOR TUF gloss-black powder coat are specified for long-haul durability and finish maintenance.

Skip it if you need passenger-side storage; Weather Guard 173-5-04 offers the same listed 3.4-cubic-foot capacity on that side.

A good fit for fleet operators or individual work-truck owners seeking driver-side storage with weather sealing and coded key management. The supplied listing does not specify vehicle fit, so the dimensions and installation location deserve attention.

4. Weather Guard 173-5-04

Why it ranks #4: This passenger-side aluminum model provides 3.4 cubic feet, a full weather seal, and a lock-and-latch system designed to resist picking.

The aluminum box measures 46.63 by 15.43 by 16.4 inches, giving buyers concrete dimensions to compare with their available bed space. A full weather seal helps shield stored gear from the elements, and the automotive-grade lock-and-latch system is specified to guard against picking. Owners managing multiple boxes can code them to work with one key. Its ARMOR TUF gloss-black powder coat is described as supporting rugged dependability and maintenance over long use.

Skip it if you need a driver-side box; Weather Guard 172-5-04 lists the same 3.4-cubic-foot capacity for that orientation.

Consider this for work-truck owners who need passenger-side capacity and want weather sealing with a coded key arrangement. Compare its listed 46.63-by-15.43-by-16.4-inch size with available bed space before choosing.

#5 · Best Steel Build

5. Dee Zee DZ95D Steel

• Dimensions: 21"L x 20"W x 9"H
• Weight: 45 lb
• Material: Alloy Steel

Best for: Steel drawer-based bed organization.

Why it ranks #5: Its alloy-steel construction, lockable drop-down door, five sliding drawers, and included quick-release mounting hardware make it a distinctive organized-storage option.

Five sliding drawers behind a single lockable drop-down door make the Dee Zee DZ95D a choice for buyers who want separated storage rather than one open wheel-well compartment. Its thick-gauge steel body has a protective black powder coat, and a quick-release bracket is listed for mounting.

The five drawers provide individual places to sort tools and supplies, while the lockable door closes over them to keep the stored contents secured. Thick-gauge alloy steel and a protective powder coat form the box’s stated construction, and included mounting hardware with a quick-release bracket supports installation and removal. The 21-by-20-by-9-inch dimensions and 1.9-cubic-foot capacity give buyers specific space figures to consider alongside its listed driver- or passenger-side use.

Skip it if you need a lighter ABS box for a 2019–2020 Silverado 1500; VEVOR’s driver-side Chevrolet/GMC model weighs 11 pounds.

This fits buyers prioritizing drawer-by-drawer organization and a lockable door in a steel wheel-well box. Consider its 45-pound listed weight and 21-by-20-by-9-inch dimensions when planning placement and installation.

6. Dee Zee DZ94B Aluminum

• Dimensions: 38 x 20 x 8 in
• Weight: 1.38 lb

Best for: Passenger-side lift-lid storage.

Why it ranks #6: This passenger-side box uses non-rusting Brite-Tread aluminum, a lockable lift-up lid, and a piano hinge; the listing cites fit for 6- and 8-foot beds.

A lockable lift-up lid on a sturdy piano hinge gives the Dee Zee DZ94B straightforward access to passenger-side wheel-well storage. Its 0.056-inch Brite-Tread aluminum body has a gloss-black powder coat, while the wheel-well placement adds storage and leaves bed space available for cargo.

The lift-up lid opens the box from above, and its full-length piano hinge supports that access arrangement along the lid’s length. A lockable lid provides a way to secure stored items, while the non-rusting Brite-Tread aluminum construction and protective gloss-black powder coat are specified materials and finish. At 38 by 20 by 8 inches, it offers defined dimensions for planning bed placement; the listing says it fits 6- and 8-foot bed pickups.

Skip it if you want drawers instead of an open lift-lid compartment; Dee Zee DZ 95D has five sliding drawers behind a lockable door.

This suits pickup owners seeking simple passenger-side storage with a lockable top-opening lid while preserving cargo-bed space. Its 38-by-20-by-8-inch dimensions and overhead lid movement are important placement considerations.

Best for: F-150 owners wanting combination access.

Why it ranks #7: This 6.6-gallon driver-side ABS box lists compatibility with Ford F-150 models from 2015–2021 and includes a combination padlock.

A combination padlock paired with a lockable box gives this VEVOR model a key-free access option for the driver side of 2015–2021 Ford F-150 trucks. Its 6.6-gallon ABS storage compartment uses wheel-well space, with a pivot-out design intended to save space.

The 25-liter capacity provides a place for truck-bed gear, while the pivot-out design brings the box outward for access without relying on a fixed position. Its ABS and carbon-steel construction is described as lightweight and rigid, and the product information cites resistance to impact, corrosion, water, dust, and sun exposure. A combination padlock and lockable box provide its stated security approach. This is specifically listed for the driver side of 2015–2021 Ford F-150s.

Skip it if you drive a 2002–2018 Dodge Ram and want a movable tray; VEVOR’s passenger-side Ram box lists that fit and feature.

This is aimed at 2015–2021 F-150 owners who want driver-side storage with combination-padlock access and a pivot-out layout. Its specified application is narrow, so trucks outside that fit are not covered by the listing.

8. VEVOR Silverado Sierra Box

• Weight: 11 lb
• Material: Acrylonitrile Butadiene Styrene

Best for: Silverado and Sierra driver-side fit.

Why it ranks #8: The driver-side ABS box is listed for Chevrolet Silverado 1500 and GMC Sierra 1500 models from 2019–2020, with a lockable lid and organizer tray.

A lockable lid and included organizing tray give this VEVOR box a defined place for both secured gear and smaller loose items. Its listed fit is for the driver side of 2019–2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, with 6.6 gallons of storage.

The ABS composite body is described as lightweight while remaining rigid, and the product listing gives a 75-pound maximum weight recommendation. A built-in lock and key secure the lid, while the supplied tray separates smaller pieces from the main compartment. At 28.3 by 8.7 by 15.4 inches, this box uses wheel-well space on the specified driver-side applications; screws, nuts, rubber pads, and plastic buckles are included for mounting.

Skip it if you own a 2015–2021 Ford F-150 and want a combination padlock; VEVOR’s F-150 driver-side box includes one.

Choose this for a listed 2019–2020 Silverado 1500 or Sierra 1500 when a lock, tray, and compact driver-side storage matter. Its stated vehicle fit is specific, so other truck applications are outside the supplied fit information.

Listed on Amazon as: VEVOR Truck Bed Storage Box, Lockable Lid, Waterproof ABS Wheel Well Tool Box 6.6 Gal/20 L, Compatible with Chevrolet Silverado 1500 GMC Sierra 1500 2019-2020, Driver Side, Black

9. VEVOR Ram 25L Box

• Dimensions: 31.5"L x 8.78"W x 15.12"H
• Weight: 15 lb
• Material: Acrylonitrile Butadiene Styrene

Best for: Ram owners wanting movable storage.

Why it ranks #9: This passenger-side ABS box lists compatibility with Dodge Ram 1500, 2500, and 3500 models from 2002–2018 and includes a movable tray.

A movable tray inside its 6.6-gallon ABS box gives 2002–2018 Dodge Ram 1500, 2500, and 3500 owners a way to separate small essentials from larger gear. The passenger-side design rotates 180 degrees for access, while its combination lock adds a locking option.

The 25-liter capacity can hold tools, clothing, drinks, and other essentials, and the movable tray lets you arrange smaller items apart from bulkier contents. A 180-degree rotating design brings the box around for access rather than requiring you to reach straight into a fixed compartment. This passenger-side model is listed for specified 2002–2018 Ram trucks and requires drilling; the included combination lock, key, clips, nuts, and screws support its installation and use.

Skip it if you have a Silverado 1500 or Sierra 1500 from 2019–2020; VEVOR’s Chevrolet/GMC driver-side box is listed for those trucks.

A practical match for owners of the listed 2002–2018 Dodge Ram models who want rotating access and a tray for mixed gear. It is passenger-side only, and installation requires drilling.

#10

10. Dee Zee DZ95P Plastic

• Dimensions: 37 x 7.75 x 19.5 in
• Weight: 10 lb
• Material: Plastic

Best for: Reversible-side plastic storage.

Why it ranks #10: The lockable plastic box reverses for driver- or passenger-side use, but the listing says it is not custom-fit and excludes Chevy Silverado EV.

A reversible lid lets the Dee Zee DZ95P shift between driver- and passenger-side applications, giving buyers flexibility over which wheel well holds storage. The 37-inch plastic box has a full-length hinge and lockable lift-up lid, and its listing specifically excludes the Chevy Silverado EV.

The reversible setup supports either side of the truck, while the lockable lift-up lid provides access from above and a way to secure the compartment. Its full-length hinge runs along the lid, and the plastic construction offers an alternative to the metal boxes in this roundup. The 37-by-7.75-by-19.5-inch dimensions help with placement planning, and installation hardware is listed as included. The stated Silverado EV exclusion is a significant fit boundary.

Skip it if you own a Chevy Silverado EV; this box is explicitly excluded, while VEVOR’s 2019–2020 Silverado 1500 box lists a different Silverado application.

Choose this if you want a plastic wheel-well box whose side can be reversed and a lockable lift-up lid. It is not suitable for a Chevy Silverado EV, and its listed dimensions should guide placement.
