Slip-In Fiberglass Service Bodies That Move With Your Truck

A slip-in fiberglass service body slides into the bed of your full-size pickup and turns it into a lockable, weatherproof mobile workshop. You keep your truck, there is no chassis swap, and when you replace the pickup, the body moves to the new one in about 90 minutes. SpaceKap builds three models, Compak, Wild and Diablo, for 6.5' and 8' beds.

What is a slip-in service body?

A traditional steel service body replaces your pickup bed: the bed comes off, the body bolts to the chassis, and the two stay together for the life of the truck. A slip-in service body works the other way. It sits in the bed you already have, so the pickup stays a pickup.

SpaceKap bodies are molded in fiberglass with a UV-resistant gelcoat. Fiberglass does not rust, so road salt, rain and snow are not a corrosion problem. Stainless steel doors, 40/60 rear doors and a 40" LED light bar come on all three models.

The result is an enclosed, lockable workspace. Tools and parts stay dry, organized and out of sight, which an open utility bed cannot offer. If you are weighing the two styles, read open vs enclosed service body and utility bed vs service body. Many contractors call it a work cap: see our commercial truck caps.

Will a SpaceKap fit my truck?

Every SpaceKap model fits full-size pickups with a 6.5' or 8' bed. The body pairs with 4WD pickups, so you keep the traction you bought the truck for.

To check your exact truck, use the truck compatibility checker or ask a SpaceKap dealer or representative.

Moving the body to your next truck

Trucks get replaced long before a fiberglass body wears out. Because a SpaceKap slips into the bed instead of bolting to the chassis, it moves with you. The full transfer takes about 90 minutes, and lifting the body off the old truck with a forklift takes about 5 minutes of that.

For a fleet, the body becomes an asset you keep across several vehicle cycles instead of paying for a new upfit with every truck. See why SpaceKap bodies are service units that stand the test of time.
