UWS wheel well tool boxes provide optimized storage and security for your items in the bed of your truck. They are designed to mount in the truck bed, integrating with the wheel wells to maximize the space for other cargo (mounting hardware not included). Each box features a corrosion-resistant aluminum construction, a stainless steel locking system, a patented RigidCore foam-filled lid and integrated drawers -- all to keep your equipment and valuables safe, well-organized and easily accessible whenever needed. Each UWS truck tool box is constructed from extra-thick aluminum for increased structural strength. The tub is welded together into a single piece for weather resistance and to easily hold heavy tools and other items. The lid features a patented RigidCore foam-filled design, sandwiched between two aluminum plates. This greatly increases the strength of the lid and helps prevent bending and warping, making operation very smooth. The locking mechanism of the UWS fender tool box provides excellent security for your items, featuring a stainless steel, key-operated paddle handle for long-lasting corrosion resistance. For solid protection against the elements, the lid also has a MicroSeal gasket, blocking moisture, dust and insects from getting inside. The lid also opens a full 90 degrees for easier access, and it is equipped with self-opening struts for convenient operation when your hands are full. The three drawers of this tool box allow you to keep your tools well-organized and secure. They are locked behind a small, rear-facing door, keeping them safe from theft and the elements. They are constructed from commercial-grade, precision-injected plastic, and they slide on stainless steel ball bearings and sliders for excellent corrosion resistance. UWS truck fender tool boxes are available in multiple sizes to accommodate any storage need (NOTE: This product is heavily packaged for parcel shipping).

UWS designs and builds heavy-duty truck tool boxes and storage for tradespeople and truck owners. The line covers crossover and side-mount boxes, chest boxes, underbody boxes, transfer tanks and dog boxes. Every aluminum box is designed, fabricated and welded in Perry, Florida, with construction aimed at job-site abuse, road vibration and daily use.
UWS is a leading manufacturer and designer of truck tool boxes and truck accessories, and a Lippert brand. The company's focus is narrow and deliberate: storage that stands up to being opened and slammed shut dozens of times a day, loaded past what looks reasonable, and left outdoors in whatever weather the job brings. Its customers are electricians, plumbers, contractors, farmers, outdoorsmen and truck owners who treat a pickup as a working tool rather than transport.
The catalog covers the full range of bed storage. Crossover boxes sit across the bed behind the cab in single-lid, gull-wing, secure-lock and low-profile styles, so there is a fit whether the priority is capacity, rear visibility or working under a tonneau. Side-mount boxes mount along the bed rails and keep the bed floor free for cargo, while underbody boxes tuck beneath the frame rails of service bodies and flatbeds.
Beyond the bed, UWS makes portable chest boxes that move between vehicles and the shop, transfer tanks and combination tank-and-toolbox units for crews working away from fuel supply, and insulated, ventilated dog boxes for hunters and handlers.
Manufacturing sits at the centre of the brand's identity. Every UWS aluminum tool box is designed, fabricated and welded in Perry, Florida, by tradespeople with decades of experience, and the company's Rooted in Trades initiative is built around that connection to skilled manual work. Boxes use heavy-gauge aluminum, continuous welds at the seams, weather stripping to seal against rain and dust, and locking systems intended to resist tampering. The practical result is storage that keeps tools dry, organized and where they were left.

The box includes the truck fender tool box itself and two keys. Hardware (bolts, flat washers, and nylock nuts) is not included and must be purchased separately.
The manual does not specify which truck models or bed styles are compatible with this tool box. Contact CURT Group at 877.287.8634 or consult your dealer to confirm fitment for your specific vehicle before purchasing.
The paddle handle must clear the bed rail for proper operation. During installation, you should verify this clearance. If the handle does not clear, a custom shim may need to be placed under the tool box to raise it and allow handle access.
Yes, the lid must open properly when the tool box is mounted. During Step 1, you should verify that the lid opens fully before drilling. If it does not, a custom shim may be needed under the tool box.
You will need: a drill, drill bit set (including 1/4" bits), ratchet, socket set, and tape measure. The installation is rated as Easy difficulty.
You must purchase bolts, flat washers, and nylock nuts separately. The manual provides torque specifications for M6, M8, M10, and M12 metric bolts, or 1/4", 5/16", 3/8", 7/16", and 1/2" SAE bolts. The exact size and quantity depend on your truck bed configuration. Consult your dealer or CURT Group for specific hardware recommendations for your vehicle.

Before drilling, check under your vehicle to ensure the drill location does not puncture, cut, or obstruct any brake lines, fuel lines, electrical wires, fuel tanks, or other components. Take precaution that all fasteners near the fuel tank do not create the possibility of fuel tank puncture or other damage during a collision.
All holes are 1/4" diameter. You drill 1/4" holes in the tool box at two locations on the lip of the bed rail and two locations on the base where the drawers were removed. You then use these holes to mark and drill matching 1/4" holes in the truck bed and bed rail.
Yes, drilling creates permanent holes in the truck bed. All fasteners and exposed metal in any holes drilled in the vehicle must be treated or sealed to prevent corrosion.

No. Do not interfere with factory-installed safety equipment. During installation, ensure the tool box does not obstruct or damage any factory safety systems.
Ensure all knobs, bolts, screws, straps, and locks are firmly secured before every trip. Periodically re-tighten and inspect all components for signs of wear, corrosion, and fatigue. With the tool box installed, periodic inspections should be performed to ensure all mounting hardware remains tight.
Use mild automotive detergent to clean the product. Do not use dish detergent, abrasive cleaners, abrasive pads, wire brushes, or other similar products that may damage the finish. For polished, gloss, and other smooth finishes, polish may be used to clear small scratches and scuffs. All fasteners and exposed metal in any drilled holes must be treated or sealed to prevent corrosion.
