Chevy Silverado Camper Shell — LEER Truck Cap
Our LEER 100XL camper shell transforms your Silverado bed into secure, weatherproof cargo space. We build each cap with one-piece fiberglass construction, eliminating seams that invite leaks or wind noise. Full-perimeter bulb seal and dual-action rear door latches keep rain, snow, and road dust outside while you carry tools, camping gear, or fragile cargo.
This cap pairs the Silverado's OEM paint codes with a durable gel-coat finish, so the shell matches your truck's color from the factory. We integrate the 100XL's profile to sit flush with the cab roof line, preserving the Silverado's aerodynamics and sight lines. Three side windows with flush-mount latches deliver natural light and cross-ventilation when you need it.
What makes this LEER cap ideal for your Silverado
Fiberglass construction and paint-match finish
We mold each 100XL cap from a single fiberglass shell, eliminating the seams found in aluminum or composite designs. That one-piece construction resists flex and vibration even on rough roads, so the seal stays tight year after year.
The factory gel-coat finish is available in dozens of OEM Silverado color codes — Summit White, Black, Silver Ice Metallic, and every factory hue from 1999 forward. Our mixing process matches GM’s paint formula so the cap blends into the truck’s body line. UV inhibitors in the gel-coat prevent fading and chalking through sun exposure and frequent washing.
Weather sealing and secure cargo protection
Full-perimeter bulb seal
A continuous rubber bulb seal runs the entire perimeter of the cap base, compressing against the Silverado bed rail when the cap is clamped down. This seal sheds rain at highway speeds and keeps dust out during off-road use.
Dual-action rear door
The 100XL rear door uses a two-point latch system with paddle handles inside and out. Each latch engages a striker mounted to the fiberglass frame, pulling the door tight against its own dedicated seal. Screened vents in the rear corners let moisture escape without inviting insects or debris inside.
Side windows and ventilation
Three frameless side windows — driver, passenger, and rear passenger — slide open on bronze-anodized tracks. Each window locks with a flush-mount latch that sits even with the fiberglass surface, eliminating snag points and maintaining clean body lines.
When the windows are cracked open, air flows through the cab and out the screened rear vents, preventing condensation on damp mornings or after a rainstorm. The carpeted headliner absorbs minor moisture and insulates the cargo area from summer heat.

Camper shell questions for Silverado owners
The LEER 100XL is manufactured for all three Silverado bed sizes: 5.8 ft short bed, 6.6 ft standard bed, and 8 ft long bed. When you order, specify your Silverado's model year and bed length so we can confirm the correct cap dimensions. Each cap is generation-specific to ensure the mounting points and cab-height profile match your truck exactly.
We use GM's OEM paint codes to mix the gel-coat finish. You provide your truck's color name or paint code (found on the door jamb sticker), and we match it to the factory formula. Common Silverado colors like Summit White, Black, Silver Ice Metallic, and Red Hot are kept in stock. Custom or special-order colors may add one to two weeks to production time.
We recommend two people for installation because the cap weighs approximately 150 pounds and requires alignment over the bed rails. One person can steady the cap while the other tightens the mounting clamps. The entire process takes 30 to 60 minutes with basic hand tools. All hardware and step-by-step instructions are included.
No. The 100XL sits on the bed rails and does not extend past the tailgate, so your factory backup camera and parking sensors remain fully visible and functional. The cap's rear window is positioned above the tailgate, maintaining your sight lines when reversing.
The cap mounts directly to the Silverado bed rails, so spray-in or drop-in bed liners do not affect installation. You will need to remove any existing tonneau cover before installing the cap, as both accessories occupy the same mounting points. If you want partial bed coverage, consider our folding tonneau models that install forward of the tailgate.
LEER's limited lifetime warranty covers the fiberglass shell against cracks, delamination, and structural defects for as long as you own the truck. The gel-coat finish is warranted against fading and chalking for five years. Hardware, latches, and glass are covered for one year. The warranty is transferable if you sell the truck with the cap installed.
Yes. The 100XL fiberglass roof is rated to support aftermarket roof racks and crossbars. We recommend racks designed specifically for truck caps, with mounting feet that clamp to the cap's drip rails. Check the rack manufacturer's weight rating and ensure even load distribution to avoid stressing the fiberglass.
