Best Fender Well Tool Boxes For Trucks: Compare 10 Options

#1 · Best Overall

1. UWS EC30001

• Dimensions: 8.75"L x 48"W x 24.75"H
• Weight: 39 lb
• Material: Aluminum

Best for: Drawer-organized work trucks.

Why it ranks #1: The 48-inch driver-side aluminum box combines three integrated drawers, a RigidCore lid, a MicroSeal gasket, and a listed 3.9-cubic-foot capacity.

Three rear-facing sliding drawers make the UWS EC30001 a wheel-well box for workers who want separate, reachable tool compartments. Its 48-inch driver-side profile integrates with the fender area, while a lockable rear door secures the drawers behind it and a reinforced RigidCore lid covers the box.

The three integrated drawers—one 3-inch-high drawer and two 2-inch-high drawers—provide distinct places for smaller tools, reducing the need to sort through one open compartment. Because the drawers face rearward and sit behind a lockable door, access follows the truck-bed rear-door side. The 48-inch aluminum box integrates with the wheel well, reserving other bed space for cargo. A MicroSeal gasket helps keep out dust, debris, and moisture; mounting hardware is not included.

Skip it if you need included mounting hardware; the Dee Zee DZ95D listing says hardware is included with its five-drawer box.

Choose this UWS for driver-side storage where separated drawers and a sealed, reinforced lid suit work tools. Its 48-inch footprint and rear-facing drawer access matter when planning bed layout, and installation requires separately sourced mounting hardware.

#2 · Best Passenger Side

2. UWS EC30032

• Weight: 41 lb

Best for: Passenger-side drawer storage.

Why it ranks #2: This 48-inch passenger-side fender box offers three rear-facing drawers, heavy-wall aluminum construction, a RigidCore lid, and a MicroSeal gasket.

Three rear-facing sliding drawers separate tools in the passenger-side UWS EC30032, keeping organized storage tucked into the truck’s wheel-well area. A lockable rear door covers the drawers, while the 48-inch heavy-wall aluminum box uses a reinforced RigidCore lid for the top compartment.

The drawer set includes one 3-inch-high drawer and two 2-inch-high drawers, providing separate places for tools of different sizes. Their rear-facing arrangement puts access at the rear door, which locks behind them. The passenger-side box integrates with the wheel well to preserve other bed space; its MicroSeal gasket helps keep out dust, debris, and moisture. The RigidCore lid is reinforced, and mounting hardware is not included, an important detail for installation planning.

Skip it if you want driver-side placement; the UWS EC30001 offers the same three-drawer arrangement as a driver-side model.

The EC30032 suits buyers who want passenger-side access to sorted tools and a lockable drawer area in a wheel-well box. Plan around its 48-inch profile and source mounting hardware separately for installation.

#3 · Sealed Aluminum

3. Weather Guard 172-5-04

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

Best for: Fleet key management.

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

A codable lock system lets one key manage this Weather Guard box or a fleet of compatible boxes, making it a practical fit for shared truck operations. The driver-side aluminum wheel-well unit provides 3.4 cubic feet of storage, with a full weather seal and black ARMOR TUF powder coat.

The lock-and-latch system is described as resisting picking, while the coding feature lets a fleet manager configure boxes around a single key. That can simplify key handling across trucks without changing the box’s driver-side placement. Its full weather seal helps protect tools from the elements, and the ARMOR TUF powder coat is specified for long-haul durability. The aluminum diamond-plate box offers 3.4 cubic feet of storage, with dimensions of 46.63 by 15.43 by 16.4 inches.

Skip it if you need a passenger-side box; the UWS EC30032 is the listed passenger-side model with integrated drawers.

Fleet operators and individual drivers seeking sealed, lockable driver-side storage can make use of the codable key system. Its specified side and 3.4-cubic-foot capacity should guide placement and gear-planning decisions.

#4 · Driver-Side Aluminum

4. Dee Zee DZ95

• Weight: 22 lb
• Material: Aluminum

Best for: Driver-side Brite-Tread storage.

Why it ranks #4: This driver-side Brite-Tread aluminum box has a lockable lift-up lid, a piano hinge, and a listed 2.2-cubic-foot capacity.

A lockable piano-hinge lid gives the Dee Zee DZ95 straightforward driver-side access to its 2.2 cubic feet of wheel-well storage. Its non-rusting 0.056 Brite-Tread aluminum construction provides a defined place for tools while leaving the truck bed’s central area open for cargo.

The driver-side placement and behind-the-wheel-well form use space that can otherwise interfere less with central bed cargo, making this a simple storage layout for tools. Its 2.2-cubic-foot capacity provides room within the box, while the lockable lift-up lid gives access from above. A sturdy piano hinge supports the lid, and Brite-Tread aluminum is specified as non-rusting. The listing identifies fit for 6- and 8-foot bed pickups, which makes bed length part of the selection.

Skip it if you need passenger-side access; the Dee Zee DZ94 offers the same listed 2.2-cubic-foot capacity on the passenger side.

This DZ95 suits buyers seeking driver-side, lockable aluminum storage for tools while preserving central bed space. Its stated 6- and 8-foot bed fit and driver-side orientation are the main considerations when planning placement.

#5 · Passenger-Side Aluminum

5. Dee Zee DZ94

• Weight: 17 lb
• Material: Aluminum

Best for: Passenger-side aluminum storage.

Why it ranks #5: The passenger-side Brite-Tread aluminum box provides a lockable piano-hinge lid and a specified 2.2-cubic-foot capacity.

Passenger-side placement distinguishes the Dee Zee DZ94, a Brite-Tread aluminum box that stores tools behind the wheel well without using the bed’s central cargo area. Its lockable lift-up lid uses a sturdy piano hinge, and the raw aluminum finish keeps the box in an uncoated-metal style.

The passenger-side application makes this model useful when a driver-side box would conflict with the intended bed layout. Its 2.2-cubic-foot capacity provides space for tools, while the lift-up lid opens from above and locks when closed. The sturdy piano hinge supports that lid movement, and the non-rusting Brite-Tread aluminum construction is specified for the box. It is listed for 6- and 8-foot bed pickups, so bed length and side placement inform the choice.

Skip it if you need driver-side placement; the Dee Zee DZ95 is the corresponding driver-side Brite-Tread model with 2.2 cubic feet of capacity.

Choose the DZ94 when passenger-side access, aluminum construction, and lockable lift-up storage fit your 6- or 8-foot bed pickup. Its passenger-side orientation is the key boundary when coordinating it with other bed-mounted equipment.

#6

6. Dee Zee DZ95D

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

Best for: Small-tool drawer sorting.

Why it ranks #6: Its heavy-gauge steel construction, lockable drop-down door, five sliding drawers, and included quick-release mounting bracket suit buyers prioritizing organization.

Five sliding drawers behind one lockable drop-down door make the Dee Zee DZ95D a compartment-focused choice for wheel-well storage. Its thick-gauge steel body has a protective black powder coat, and the box is listed for either driver- or passenger-side placement in 6- and 8-foot bed pickups.

The five drawers let buyers sort smaller tools into separate compartments instead of stacking them in one open space; the lockable drop-down door covers the drawer area. Its 1.9-cubic-foot capacity provides a defined storage zone while leaving the truck bed available for hauling. The thick-gauge steel construction and black powder coat are specified for the box, while included mounting hardware and a quick-release bracket address installation and removal workflow. The unit weighs 45 pounds.

Skip it if you need more than 1.9 cubic feet; the UWS EC30001 lists 3.9 cubic feet of capacity and integrated drawers.

This Dee Zee suits buyers who value drawer-by-drawer organization and a quick-release bracket for a wheel-well box. Its 1.9-cubic-foot capacity is the key storage boundary for anyone deciding how much equipment to keep aboard.

7. Dee Zee DZ95B

• Dimensions: 38"L x 20"W x 8"H
• Weight: 17.3 lb
• Material: Aluminum

Best for: Black-finish driver-side storage.

Why it ranks #7: This driver-side aluminum box has a protective gloss-black powder coat and lockable piano-hinge lid; its listed maximum weight recommendation is 80 pounds.

A gloss-black powder coat over Brite-Tread aluminum gives this Dee Zee driver-side box a finished look alongside non-rusting construction. Its lockable lift-up lid opens on a sturdy piano hinge, while the wheel-well form keeps tool storage tucked behind the truck’s fender area.

The 38-by-20-by-8-inch box fits behind the wheel well, keeping its storage footprint in that area rather than occupying the bed’s central cargo space. A piano hinge supports the lift-up lid, and the lockable closure secures tools inside. The 0.056 Brite-Tread aluminum is paired with a protective gloss-black powder coat, and the listing gives an 80-pound maximum weight recommendation. It is specified for driver-side use and 6- and 8-foot bed pickups.

Skip it if you need passenger-side placement; the Dee Zee DZ94 is the listed Brite-Tread passenger-side wheel-well box.

This Dee Zee fits drivers seeking black-finished, lockable aluminum storage behind the wheel well on a 6- or 8-foot bed pickup. Its driver-side application is the relevant boundary when mapping storage to the rest of the bed.

#8

8. VEVOR Ford F-150 Box

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

Best for: Ford F-150 tool organization.

Why it ranks #8: This 25-liter ABS box is specified for the driver side of 1997–2014 Ford F-150 trucks and features a movable tray and 180-degree rotation.

A 180-degree rotating design brings this VEVOR box’s contents around for access, pairing 6.6 gallons of storage with a movable organizing tray. It is specified for the driver side of 1997–2014 Ford F-150 trucks, where its wheel-well placement makes a defined home for tools and other essentials.

The rotating design can bring the storage area into reach without treating the box as a fixed, front-access compartment, while the movable tray helps separate smaller items from the main 25-liter capacity. The ABS body is described as impact resistant, and the listing identifies waterproof construction. A combination lock and key secure the contents. Installation requires drilling, so the specified F-150 fitment and the buyer’s willingness to drill are central considerations before choosing it.

Skip it if you do not want to drill during installation; the Dee Zee DZ95B is listed as a wheel-well box without a drilling requirement.

This VEVOR is for owners of a 1997–2014 Ford F-150 seeking rotating, lockable driver-side storage with a movable tray. Its drilling requirement and specific vehicle fitment are important boundaries for installation planning.

9. VEVOR Silverado Box

• Dimensions: 28.3"L x 8.7"W x 15.4"H
• Weight: 11 lb
• Material: Acrylonitrile Butadiene Styrene

Best for: Silverado and Sierra drivers.

Why it ranks #9: This lockable 25-liter ABS box is specified for the driver side of 2019–2020 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks.

A keyed, lockable lid gives this 6.6-gallon VEVOR box a defined place for tools in compatible 2019–2020 Chevrolet Silverado 1500 and GMC Sierra 1500 L beds. Its driver-side layout uses wheel-well space, while the ABS body and included organizational tray help keep gear sorted and protected.

The 28.3-inch-long ABS box is specified for the driver side of the listed Silverado and Sierra models, making its vehicle-specific fit the key selection point. Its 6.6-gallon capacity and organizational tray separate smaller items from the main storage area, while the swiveling design provides access to stored gear. The lockable lid uses a key, and the thick ABS construction is described as weather-resistant. Installation hardware is included, and the stated maximum weight recommendation is 75 pounds.

Skip it if you drive a different truck; the Dee Zee DZ95 fits 6- and 8-foot bed pickups according to its listing.

This VEVOR suits Silverado 1500 and Sierra 1500 L owners seeking lockable, organized driver-side storage in the specified 2019–2020 fitment. Its vehicle-specific compatibility is the main boundary, so it is not a general-purpose box for other trucks.

Listed on Amazon as: VEVOR Truck Bed Storage Box, Compatible with Chevrolet Silverado 1500 GMC Sierra 1500 2019-2020 L, Waterproof ABS Wheel Well Tool Box with Lockable Lid, 6.6 Gal/25 L Truck Toolbox, Driver Side, Black

#10

10. Dee Zee DZ95P

• Weight: 10 lb
• Material: Plastic

Best for: Reversible-side plastic storage.

Why it ranks #10: The listing identifies a 37-inch plastic wheel-well box with a reversible lid for either side, but provides less material and capacity detail than higher-ranked options.

A reversible lid lets this Dee Zee poly-plastic wheel-well box serve either the driver or passenger side, giving buyers flexibility when choosing a bed layout. The 37-inch lift-up box sits behind the wheel well, with a lockable lid and full-length hinge for access to stored tools.

The reversible lid supports either-side application, which helps when the preferred mounting side depends on how the truck bed is used. Its 37-inch size is intended to fit behind the wheel well, and the lift-up lid opens the storage area from above. A full-length hinge supports the lid along its length, while the lockable closure secures contents. The supplied listing identifies poly plastic construction; its stated boundary is that it does not fit the Chevy Silverado EV.

Skip it if you own a Chevy Silverado EV; the Dee Zee DZ95B is an aluminum wheel-well option listed for 6- and 8-foot bed pickups.

Consider this Dee Zee if reversible-side placement and a lockable lift-up lid suit your truck-bed setup. The Silverado EV exclusion is explicit, so buyers of that vehicle should choose a different listed option rather than rely on this box.
