Types of Truck Tool Boxes

The right truck tool box depends on how you use your bed, what you carry and where you need to reach it from.

  • Crossover Truck Tool Boxes: The most common style. A crossover (saddle) box spans the bed just behind the cab and rests on both bed rails, leaving the bed floor open beneath it. Choose a single lid or gull wing lid, or a low profile truck tool box that sits lower to keep your rear view clear.
  • Lo-Side / Side Mount Boxes: Mount along one bed rail at a low profile, keeping the center of the bed open for long material. Many buyers run a matched pair.
  • Top Mount Boxes: Sit on top of the bed rail with more height and capacity than a lo-side box, while still leaving the bed floor open.
  • Truck Tool Chests: Freestanding chest boxes that sit on the bed floor, usually against the front wall, so the bed rails stay clear.
  • Underbody Boxes: Mount beneath a flatbed, service body or frame, completely out of the bed. Available in single- and double-door configurations.
  • Wheel Well Boxes: Also called pork chop boxes. Fit beside the rear wheel well inside the bed, in driver-side and passenger-side versions.
  • Flatbed Boxes: Built for trucks with flatbed or platform bodies rather than a pickup bed.
  • Backpack Boxes: Large boxes that mount behind the cab at the front of the bed for maximum capacity.
  • Truck Tool Box Accessories: Replacement locks, keys, hinges and mounting hardware.

Aluminum vs. Steel Truck Tool Boxes

  • Weight: Aluminum is lighter than steel, which is easier to handle and saves payload. Steel is heavier and feels more solid.
  • Rust and corrosion: Aluminum resists rust without a coating. Steel relies on its powder coat finish; touch up any chips.
  • Cost: Steel usually costs less for the same storage capacity.
  • Best for aluminum: wet or coastal climates, half-ton trucks, and boxes you move between trucks.
  • Best for steel: budget-driven fleets and heavy daily commercial use.

How to Choose the Right Truck Tool Box

  1. Decide where you need access. Grab tools from behind the cab: crossover. Need the bed open for material: lo-side or top mount. Need the bed completely clear: underbody.
  2. Measure your bed rails. Crossover box length matches bed width, not bed length. Full-size pickups typically take a box around 69 to 72 inches; mid-size trucks (Tacoma, Colorado, Canyon, Ranger, Frontier) around 60 to 63 inches. Check the listed dimensions against your bed, or shop by truck above.
  3. Choose your material. Aluminum for light weight and rust resistance, steel for lower cost.
  4. Choose a lid and profile. Single lid or gull wing, standard or low profile.
  5. Confirm the install method. Many crossover and lo-side boxes clamp to the bed rail with J-bolts. Underbody and service body boxes may need drilling. Check the product page before ordering.

Who Uses Truck Tool Boxes

  • Electricians: a crossover or lo-side box for meters and hand tools, with the bed free for conduit and wire.
  • Plumbers and HVAC technicians: underbody boxes keep tools out of sight while the bed carries pipe and equipment.
  • General contractors: crossover boxes for quick access between job sites.
  • Service technicians: chest and underbody boxes for full tool sets.
  • Fleet managers: standardize boxes across trucks. Contact us for fleet pricing.

Many crossover and lo-side boxes clamp to the bed rail with J-bolts and need no drilling into the truck. Underbody and service body boxes may require drilling. Check the install method on the product page.

What size truck tool box do I need?

Crossover box length matches bed width, not bed length. Full-size pickups (F-150, Silverado, Sierra, RAM, Tundra and HD trucks) typically take a box around 69 to 72 inches. Mid-size trucks (Tacoma, Colorado, Canyon, Ranger, Frontier) typically take a box around 60 to 63 inches. Always compare the box's listed dimensions with your bed rails.

What is a low profile truck tool box?

A low profile box sits lower above the bed rails than a standard crossover box, so it blocks less of your rear window view while still giving you lockable storage. Shop low profile truck tool boxes.
