Toolboxes & Cargo Storage

Crossover, chest, and side-mount toolboxes. Cargo slides, drawers, and bed organizers.

Shipped nationwide from X-Treme Truck Outfitters in San Diego, California, and installed at our Kearny Mesa shop.

Common Questions

What size toolbox fits my truck?
Crossover toolboxes are sized to the truck’s bed width and rail height, so fitment depends on your year, make, model, and bed. Call (858) 279-0240 with those details and we will confirm which boxes fit.
Can I fit a toolbox and a tonneau cover together?
Yes, but it needs the right combination. Some tonneau covers are made specifically to work with a crossover toolbox, while others are not. Call (858) 279-0240 before buying either so we can confirm the pair works on your truck.
