Tool Boxes for Full-Size Long Flatbeds - Set of 2

These aren't toolboxes that sit in your bed. They ARE your bed. Mount them on either side of your flatbed and suddenly you've got the full height of a factory bed wall — solid, flush, and ready to work.

Bolt a topper on top. Run a bed rack. Slide a camper between them. Throw on a Tunu, a Go Fast, a Super Pacific — anything designed to sit on factory bed rails works here. Because these boxes are built to exactly that height. On purpose.

And the inside? Massive. Largest boxes on the market. Period. Nearly 97 inches long and over 21 inches tall. The walls are thin aluminum — because we put the material where it matters, not where it adds weight and eats your storage. They weigh approx 85 lbs each.

Heavy duty latches. Smooth opening lids. Lockable. Weatherproof. Built from the same corrosion-resistant aluminum as your NJO flatbed.

Add the tailgate upgrade and you've got a fully enclosed bed that opens from the back just like the truck you traded in — except everything else about it is better.

This is what a serious rig looks like from the outside. Wait until you see how much fits inside.
