Fiberglass Construction & Paint Matching

We manufacture every LEER Ram 1500 bed cap using hand-laid fiberglass reinforced with composite resins that create a shell both lighter and stronger than steel alternatives. The seamless molding process eliminates leak-prone joints while maintaining structural rigidity across the entire cargo area.

Our paint-matching technology uses spectrophotometry to analyze your Ram’s factory finish, then applies identical basecoat and clearcoat layers in a controlled booth environment. The result is a color match indistinguishable from the original paint, with UV-resistant clearcoat that prevents fading even after years of sun exposure. Each cap receives a multi-stage cure process that bonds the paint at the molecular level for chip resistance that outlasts powder-coat alternatives.

Locking System & Security Features
Sizing & fit

Locking System & Security Features

The 100XL employs a three-point rotary locking mechanism that engages stainless steel strike plates mounted along the bed rail perimeter. When you turn the exterior handle, hardened steel rods simultaneously lock at the front corners and rear center, creating a theft-deterrent barrier that resists pry attempts.

We offer keyed-alike cylinder options that let you operate your bed cap and truck tailgate with a single key, eliminating the frustration of managing separate key sets. The lock housings are sealed against moisture intrusion, and all moving components receive a lifetime lubrication treatment during assembly to prevent binding in freezing conditions.

Glass Configuration & Ventilation

Tempered Glass Safety

Every side and rear window uses fully tempered glass that meets DOT safety standards for automotive applications. If impact does occur, the glass fractures into small granules rather than dangerous shards, protecting you and your cargo.

Sliding Rear Window

The rear window slides horizontally on corrosion-resistant aluminum tracks, providing ventilation that prevents moisture buildup inside the cap. The locking tab secures the window in any position, letting you fine-tune airflow based on weather conditions and cargo requirements. Tinted glass reduces interior heat gain by up to thirty percent compared to clear alternatives, keeping temperature-sensitive items cooler during summer transport.

Perfect fit for my 2021 Ram
I ordered the 100XL for my 6'4" bed and the fit is absolutely flush with the cab. Paint match on my Billet Silver is flawless—I can't tell where the truck ends and the cap begins. Installation took me and my neighbor about an hour and a half, and the instructions were clear. The sliding rear window gets daily use for ventilation.

No more wet tools after rain
I've had this cap for eight months through a brutal winter and a soaking spring. Not a single drop has made it past the seals. My cordless tools and compressor stay bone-dry, and the lock system gives me peace of mind when I park at job sites overnight.

Worth every penny for camping trips
We use our Ram for weekend camping and this cap has been a game-changer. Sleeping bags, coolers, and gear stay protected from weather and theft. The tinted glass keeps the interior cooler during summer days, and the tempered glass feels solid when we're loading heavy bins.

Aerodynamics improved my fuel economy
I was skeptical about adding weight, but my highway mileage actually improved by about half a mile per gallon after installing the 100XL. The seamless design must cut down on drag compared to my old aluminum cap. Build quality is excellent—no rattles or flexing even on rough roads.

Keyed-alike option is brilliant
I ordered mine with the keyed-alike cylinder so one key operates my truck, tailgate, and cap. It's such a simple feature but makes daily use so much smoother. The three-point lock feels substantial, and I appreciate that the handle doesn't freeze up in cold weather like my previous cap did.

Professional installation was fast
My dealer installed this in under two hours and walked me through all the features. The weather-stripping looks serious compared to cheaper caps I considered. I haul landscaping equipment and the fiberglass has held up to constant loading without cracking or showing wear after six months of heavy use.

Common Questions About LEER Ram 1500 Bed Caps

Yes, the 100XL accommodates both spray-in and drop-in bed liners. The mounting clamps adjust to account for liner thickness up to half an inch. If you have a particularly thick liner or bed rail covers, let us know during ordering so we can provide extended clamp hardware. The weather-stripping compresses to maintain a seal even with liner material present along the bed rails.

Absolutely. The clamp-based mounting system allows complete removal without leaving permanent marks or holes in your bed rails. Most owners can remove and reinstall the cap in about forty-five minutes with a second person assisting. We recommend storing the cap on padded sawhorses or a dedicated rack to prevent stress on the fiberglass during off-season months. All mounting hardware can be reinstalled multiple times without degradation.

Provide your truck's paint code during ordering—you'll find this on the driver's door jamb label, usually listed after "PNT" or "PAINT." LEER maintains formulas for all current and recent Ram factory colors. If you have a custom paint job or older color, send us a painted panel or door edge photo and we'll create a custom match using spectrophotometry. Metallics and pearls receive extra clear-coat layers to match the factory depth.

LEER provides a three-year limited warranty covering fiberglass structure, paint finish, and hardware against manufacturing defects. Glass carries a one-year warranty, and weather-stripping is covered for two years. The warranty requires professional installation or strict adherence to our DIY instructions. We also offer extended warranty options at purchase that cover accidental damage and UV fading for up to seven years.

No, the 100XL is designed to preserve full function of factory backup cameras and parking sensors. The cap sits low enough that camera sightlines remain unobstructed. If you have an aftermarket camera mounted on the tailgate, it will continue to operate normally. The integrated third brake light wiring harnesses into your truck's existing lighting system without splicing or cutting factory wires.

Yes, LEER offers compatible roof rack systems that mount directly to reinforced areas in the cap's fiberglass structure. These racks distribute weight across multiple mounting points and are rated for up to 150 pounds of evenly distributed cargo. We recommend professional rack installation to ensure proper placement and sealing of mounting bolt penetrations. Aftermarket racks not designed for LEER caps may void your warranty if they cause stress cracks.

The 100XL weighs approximately 180 pounds for a 6'4" bed configuration, varying slightly with bed length. This weight counts against your Ram 1500's payload capacity but represents less than ten percent of the typical payload rating. Fiberglass construction keeps weight lower than comparable aluminum caps while maintaining superior strength. The aerodynamic benefit often offsets the weight penalty during highway driving, as reduced drag improves fuel efficiency.
