The best truck bed tool box depends on one thing more than brand: where it sits in your bed. A crossover box spans the bed rails behind the cab, a wheel-well box tucks beside the wheel arch, a chest sits loose on the bed floor, and an underbody box mounts below the bed. We’ve grouped eight real options by type, so you can match the box to your truck first and the features second.
How we chose: we compared current Amazon listings by box type, stated size, material, lid style and stated fitment. We haven’t installed each of these ourselves, so we stick to what the listings state and to fitment checks you can do in your own driveway.

1. UWS EC10071 72-Inch Gull Wing Crossover Tool Box
- RIGIDCORE LIDS. This gull wing truck bed tool box is built for max lid strength with RigidCore technology. The lids are …
- EXTRA-THICK ALUMINUM. UWS aluminum truck tool boxes are constructed with thicker aluminum compared to most aluminum tool…
- STAINLESS STEEL HANDLES. This truck storage box is equipped with stainless steel handles for dependable security and lon…
Bottom line: This is the pick for full-size pickup owners who want a big, traditional crossover box. It’s a 72-inch heavy-wall aluminum box with gull-wing lids, so you can open it from either side of the truck.
Gull-wing lids matter more than they sound. On a full-size truck you can reach tools from the curb side without climbing into the bed.
A real limitation: A standard-height crossover sits above the bed rails and can block part of your rear-window view and some tonneau covers. Measure your rail-to-rail width and check the listing’s fitment before you order.
2. CamLocker KS71LPMB 71″ Low Profile Crossover
Bottom line: Choose a low-profile crossover like this 71-inch CamLocker if you care about your rear view. Low-profile boxes sit lower above the rails than standard crossovers. If you also run a bed cover, low-profile alone doesn’t guarantee a fit, so confirm that the cover maker lists it as toolbox-compatible with your box’s dimensions.
If you’re pairing a box with a cover, also see our guide to tonneau covers that work with a toolbox, since cover and box fitment go together.
A real limitation: Lower height means less vertical space inside. If you store tall items like a jack or bottle, check the listing’s interior dimensions first.
3. SCITOO 60″ Aluminum Crossover Tool Box
- ENHANCED LOCK PROTECTION,SECURE YOUR ON-BOARD GEAR:The SCITOO truck box features a key-operated lockable design,effectiv…
- 60″UNIVERSAL FIT DESIGN,BROAD COMPATIBILITY WITH MAINSTREAM TRUCKS:This 60 Inch truck bed tool box fits most full-size a…
- STURDY DURABLE MATERIALS,BUILT FOR US DIVERSE ENVIRONMENTS:Constructed from high-strength wear-resistant materials,this …
Bottom line: This is the budget-conscious crossover pick. The listing describes a 60-inch aluminum diamond-plate crossover box, lockable and weatherproof, with dimensions of 60″ W x 14″ D x 14″ H, for “most full size pickups”.
It’s worth a look if you want the crossover layout and have checked the price against the heavier-wall boxes above.
A real limitation: “Most full size pickups” isn’t the same as your pickup. Measure your bed width at the rails, not the floor, and compare it with the stated size before buying.
4. Dee Zee DZ8170D Red Label Crossover Tool Box
- Non-Rusting 0.056 Brite-Tread Aluminum
- Extra Deep Storage To Fit More Gear
- Double V-Pan Lid Stiffener Creates Strength And Rigidity
Bottom line: Dee Zee is an established truck-accessory brand, and this is its Red Label crossover box. Pick it if you’d rather buy from a brand you already recognize.
It suits buyers who want a crossover box from a familiar name.
What to know: The listing title doesn’t state the size, so check the product details and your bed measurements carefully. Dee Zee sells several Red Label sizes that look alike.
5. RealTruck UnderCover SwingCase SC203P (F-150)
- Fits 2015 – 2025 Ford F-150 Passenger Side (Includes Lightning)
- Made in the USA with Global Materials
- TRUCK BED COVER COMPATIBLE | The UnderCover SwingCase maintains a 3-inch clearance from the truck bed & works with virtu…
Bottom line: If you drive a 2015-2025 Ford F-150 (the listing says it includes the Lightning) and don’t want a box across the rails, a wheel-well box like this SwingCase is the alternative to a crossover. It’s the passenger-side unit.
Wheel-well boxes use the space beside the wheel arch, which leaves more of the bed floor open than a crossover.
A real limitation: It’s vehicle-specific and side-specific. SC203P is the passenger side for the F-150 years listed. If you want both sides, you’ll need the matching driver-side unit, and other trucks need a different part number.
6. VEVOR Wheel Well Tool Box (Tundra, Driver Side)
Bottom line: This is a wheel-well option for 2007-2021 Toyota Tundra owners: a lockable ABS box the listing describes as waterproof, with a password padlock, for the driver side. The listing’s capacity figures (“6.6 Gal/20 L”) don’t quite match each other, so check the product details for the real size.
It’s best for small, frequently used items like straps, gloves and a tire gauge that you don’t want sliding around the bed.
A real limitation: It’s a small box, so it won’t replace a crossover for power tools. It’s also Tundra- and driver-side-specific per the listing.
7. VEVOR 39″ Aluminum Diamond Plate Tool Box (Chest)
- Last A Lifetime: VEVOR truck tool box is constructed from lightweight yet durable aluminum alloy, featuring a diamond tr…
- Bulk-storage Toolbox: This spacious toolbox measures 39 x 13 x 10 inches, providing plenty of room for buckets, maintena…
- Nothing Is Getting In: Our truck toolbox is a must-have choice for your vehicle. It comes with an overhanging door that …
Bottom line: Pick a loose chest like this 39 x 13 x 10-inch VEVOR box if you switch trucks, need the whole bed some days, or use it on an RV or trailer too. The listing includes side handles and a lock with keys.
A chest doesn’t depend on rail width. Still measure the bed floor and tailgate clearance, and check that the lid can open with a cover or rack installed.
A real limitation: A loose chest needs to be tied down. Unsecured, it can slide or become a projectile in a hard stop. Use tie-downs to your bed’s anchor points.
8. YITAMOTOR 36″ Underbody Tool Box
- Anti-drop Net: Our underbody tool box features an innovative anti-drop net that grants a safe and secure storage space f…
- Durable: This aluminum diamond plate truck tool box is constructed with high-density aluminum and non-slip surface while…
- Embedded T-handle & Safety: The T-shaped handle is more convenient to operate; The handle folds up without bumps when th…
Bottom line: This is an underbody box: a 36-inch heavy-duty aluminum diamond-plate box with a T-handle, lock and keys, listed for pickups, RVs and trailers. It suits flatbed trucks and trailers where there’s frame space to mount it.
Underbody boxes keep the bed and rails completely clear, which is why you’ll see them on flatbeds and work trailers.
A real limitation: On a standard pickup with a normal bed, there usually isn’t an obvious place to mount an underbody box without brackets or fabrication. Check your frame and ground clearance first.
Who a Crossover Truck Bed Tool Box Is NOT For
- Short-bed owners who haul long loads: a crossover eats bed length. A wheel-well box keeps the floor clear.
- Anyone running a tonneau cover not rated for a toolbox: many covers need the full rail. Check the cover’s toolbox compatibility first.
- Drivers who can’t give up rear-window visibility: choose a low-profile model or a wheel-well box.
Buyer’s Guide: How to Choose a Truck Bed Tool Box
Which type do you need?
Crossover boxes span the rails behind the cab and are the most common full-width style. Low-profile crossovers trade some height for a clearer rear view. Wheel-well boxes keep the bed floor open. Chests sit loose on the floor. Underbody boxes mount below the bed on flatbeds and trailers.
How do you measure your truck bed for a tool box?
Measure rail-to-rail across the top of the bed (outside edge to outside edge) and the inside width between the rails, then compare both with the box’s stated dimensions. Don’t rely on “fits most full-size trucks” alone. For more ways to organize the space, see our truck bed storage guide.
How do you mount a crossover tool box without drilling?
Many crossover boxes can be secured with J-hook mounting kits that clamp the box to the bed rails instead of drilling. First confirm with your box’s maker that J-hook mounting is approved for that box. If it is and your box didn’t come with hardware, this is one kit option:
- 【Truck Toolbox J Hooks】4pack Tool Box Tie Down Sets is a Premium Aluminum Pickup Truck Bed Toolbox Mounting Kit.Toolbox …
- 【J Hook Crossover Tool Size】The dimensions of the J Hook Truck Tool Kit are Aluminum clamp 1-1/8″ x 1-1/16″, Bolt length…
- 【Material】The material of the Pickup Truck Tool Box Tie Downs Heavy Duty Rust-Free Aluminum, larger clamping area. Durab…
Check that the hook length matches your rail profile, and re-check the nuts after the first few drives.
What about locks and weather sealing?
Look for a keyed lock and a sealed lid if you store power tools. No box is truly theft-proof, so don’t leave expensive tools in it overnight in public lots.
Shopping for Black Friday or as a Christmas Gift?
A truck bed tool box is one of the bigger-ticket truck gifts, which is why many people wait for Black Friday. Before you buy, check the current price on the listing rather than assuming a deal. Large boxes can also have longer delivery windows, so check the delivery date shown on Amazon before ordering for Christmas.
If it’s a gift, get the truck’s year, make and bed length first. Wheel-well boxes are model-specific. More ideas: our Christmas gifts for truck owners.
Frequently Asked Questions
What is the best type of truck bed tool box?
For most full-size pickups, a crossover box gives the most storage. If you need more of the bed floor open, a wheel-well box is usually the better fit. If you run a tonneau cover, check the cover maker’s toolbox compatibility first.
Will a tool box fit with a tonneau cover?
Only with covers designed for it. Many covers need the full rail, so check the cover maker’s toolbox compatibility, or pair a low-profile box with a toolbox-compatible cover.
Do crossover tool boxes need drilling?
Not always. Many can be secured with J-hook rail clamps. Follow the box maker’s mounting instructions.
Aluminum or plastic tool box?
Aluminum diamond-plate boxes are the traditional choice for crossover and underbody boxes. Plastic (ABS) is common on smaller wheel-well boxes. Match the material to what you’re storing and your climate.
How do I know a wheel-well box fits my truck?
Wheel-well boxes are model- and side-specific. Match the listing’s stated years and side (driver or passenger) to your truck exactly.
Final Thoughts
If you drive a full-size pickup and want a large crossover, start with the UWS EC10071 gull-wing crossover. If you care about your rear view, go low-profile with the CamLocker, and confirm cover compatibility if you run a tonneau. If you’d rather keep the bed floor open on a 2015-2025 F-150, the UnderCover SwingCase is the cleanest option. Measure first, then buy. To protect the bed floor underneath, see our truck bed mat guide.
