LEER Silverado Truck Topper

We use your truck's factory paint code to mix the finish. You can find this code on the driver's door jamb sticker—it's usually a three-character code like WA8555 (Black) or GAN (Red Hot).

Provide that code when you place your order and we'll match it in our spray booth using the same paint suppliers GM uses. The topper ships with a color card showing the code we mixed. If the match isn't within acceptable OEM variance when you receive it, we'll refinish the affected panels at no charge.

The topper weighs between 140-165 lbs depending on bed length, so you'll need at least two people to safely lift it onto the truck. Installation itself is straightforward and takes 45-60 minutes with basic hand tools—no drilling required.

We include detailed instructions with torque specs and installation tips. The C-channel mounts bolt directly to your bed's stake pockets and adjustable clamps let you level the unit and compress the weather stripping. Many buyers install it themselves, but our dealer network offers professional installation if you prefer. Dealers typically include a water test and butyl sealant application as part of their service.

Standard-height toppers measure 18" from the bed floor to the interior ceiling at the rear, tapering forward to match the Silverado's cab roofline. This profile maintains aerodynamics and works well for most cargo needs.

High-roof models add 6" of vertical clearance, giving you 24" of headroom at the rear door. This extra space lets you store bicycles upright without removing wheels, stack taller bins, or set up a sleeping platform with sitting room. The high-roof design creates slightly more wind resistance but remains stable at highway speeds. Choose high-roof if you regularly haul tall items or plan to use the bed for camping.

The full-perimeter weather stripping creates a compression seal when the topper is properly mounted and the clamps are torqued to spec. Flush-mount hinges and frameless glass eliminate gaps where water typically enters.

Most dealers perform a water test during installation, running a hose over the topper while checking for drips inside the bed. We also recommend applying butyl tape sealant along the bed rails before mounting for extra protection. Thousands of these toppers are in daily use in rainy climates without leaking. If you do experience leaks, check that the mounting clamps are tight and the weather stripping hasn't been compressed unevenly.

No, the three-point locking rear door or liftgate gives you full access to the bed without removing the topper. You can load and unload cargo through the rear opening just like using your tailgate.

Optional sliding side windows provide access to items near the front of the bed without walking around to the rear. Some buyers add aftercut side doors for even easier access to tools and equipment. The topper is designed to stay mounted unless you need to haul something taller than the interior clearance or want to return the truck to its original open-bed configuration.

Yes, the fiberglass roof supports up to 150 lbs of static weight when paired with aftermarket crossbars or rack systems. You'll need to useracks designed for topper installation—these typically clamp to the topper's drip rails or use adhesive-mount feet.

Popular options include Thule, Yakima, and Rhino-Rack systems. Make sure the rack distributes weight evenly across the roof rather than concentrating load at specific points. This capacity is sufficient for kayaks, lumber racks, rooftop cargo boxes, or light construction materials. Avoid driving at highway speeds with heavy, tall loads as wind resistance can stress the mounting points.
