Sterling’s V375 full size premium fiberglass truck capsule is the only full-coverage truck toppers made with split molding process. That mean’s, there’s no seams filled with rubber that will later dry out and later leak. This capsule is essentially made of one mold and is completely sealed from the elements, eliminating condensation entry points. Able to be transferred between trucks by lifting from the inside roof, it’s the most durable fiberglass capsule on the market. The v375 premium full size capsule is our premium full-height slide-in unit that offers the most usable space and is compatible with most 8′ domestic truck beds. This slide-in cap comes in our Fiber Optic Splicing Cap Package or unaltered and is customizable to your preferences.

The premium full size capsule is slightly larger, and is a newer design from the V365 , giving you more head room.

To maximize storage, efficiency and accessibility some popular additions are:
• Shelving on the passenger side
• A workbench on the driver’s side
• A window on the driver’s side (above the workbench)
• A hitch access step
• A grab handle(s)

Our Truck Caps are the best alternative to a Service Body as they are more reliable, transferable and the turn-around time is far shorter. Contact Us today to learn how fast we can turn these around, or have them delivered straight to your door. These slide in capsules are a perfect addition to your pick-up.

By choosing Sterling’s commercial truck equipment, you’re choosing the most durable and versatile product and install available. We are set up to service full fleets, or one-offs! We are solution orientated and want to add value to your pick up.

Please contact us to choose your build and ask to see how this cap looked after one of our customers hit black ice and rolled onto the capsule!
