LEER 100R Truck Cap – Sleek Fiberglass Topper with Paint-Matched Finish
The LEER 100R sets the standard for sleek, low-profile truck caps with its aerodynamic design and factory-matched paint finish. We engineered this fiberglass topper to complement your truck's lines while delivering secure, weather-tight cargo protection.
Ideal for drivers who demand both style and function, the 100R features frameless, curved side glass for unobstructed visibility and a sculpted roofline that reduces wind resistance. Our proprietary LEER Secure Locking System keeps your cargo safe, while premium gas struts ensure smooth, effortless lift gate operation every time you access your truck bed.
LEER 100R construction & design highlights
Fiberglass Construction & Paint-Matched Finish
We build every LEER 100R from a single seamless fiberglass shell, eliminating weak points and creating a rigid, weather-resistant structure that stands up to years of use. Our manufacturing process applies automotive-grade primers and topcoats matched precisely to your truck’s factory color code.
The paint finish undergoes the same multi-stage process used in automotive production, ensuring consistent gloss, UV resistance, and color accuracy. Whether you drive a Ford, Chevy, Ram, Toyota, or GMC, the 100R integrates seamlessly with your truck’s aesthetic. Our LEER truck caps maintain their finish integrity through extreme temperatures, road salt exposure, and intense sunlight without fading or cracking.
Aerodynamic Profile & Glass Configuration
Sleek Roofline Design
The 100R’s sculpted roofline follows your truck cab’s contours, creating a continuous flow that minimizes wind turbulence and improves fuel efficiency. We shaped the cap’s profile using computational fluid dynamics to reduce drag while maintaining maximum interior cargo height.
Frameless Side Glass
Frameless curved side glass panels provide unobstructed sight lines and a modern, refined appearance. Each window comes factory-tinted to reduce interior heat buildup and protect your cargo from UV exposure. The front sliding window allows ventilation control and easy access to cargo without opening the rear door.
Security & Access Features
Our proprietary LEER Secure Locking System integrates a flush-mounted, rotary-style lock into the rear door handle assembly. The system operates with the same key as your truck’s ignition, eliminating the need for multiple keys on your keychain.
Premium stainless steel gas struts handle the full weight of the rear lift gate, allowing one-handed operation even when loading heavy equipment. The struts are rated for 50,000+ cycles and feature corrosion-resistant coatings for long-term reliability. Internal release handles provide emergency exit capability and meet all federal safety standards for enclosed cargo spaces.

Common Questions About the LEER 100R Truck Cap
The LEER 100R is our low-profile model with 18-20 inches of interior height, designed to minimize wind resistance while providing secure storage for most cargo types. If you need more vertical clearance, the 100XL offers 22 inches, while the 180 and 122 models provide progressively taller workspaces.
The 100R maximizes aerodynamic efficiency and fuel economy, making it ideal for highway driving and daily commuting. Interior width and length match your truck bed dimensions exactly, providing full bed coverage without wasted space.
Yes, we match every LEER 100R to your truck's specific OEM paint code using automotive-grade primers and topcoats. Our paint process replicates the multi-stage application your truck manufacturer uses, ensuring consistent color, gloss level, and texture.
We maintain an extensive database of current and legacy paint codes for Ford, Chevy, Ram, Toyota, GMC, Nissan, and other manufacturers. If your truck has a custom or aftermarket paint job, we can color-match using physical samples to achieve seamless integration.
The standard 100R features a smooth fiberglass roof designed for aerodynamics, but we offer the 100RCC model with an integrated roof rack system engineered specifically for kayaks, bikes, ladders, and cargo boxes. The RCC version includes reinforced mounting points and load distribution rails.
If you already own a 100R, we offer retrofit rack systems that attach through the cap's internal structure without compromising the fiberglass shell. These aftermarket racks support up to 150 pounds when properly installed and distributed.
Wash the 100R with the same soap and methods you use on your truck's painted surfaces, avoiding abrasive cleaners that can dull the finish. Apply automotive wax or sealant every 3-4 months to protect against UV damage and maintain gloss.
Inspect the bulb seal and side curtains twice yearly, cleaning debris from the channels and applying silicone lubricant to maintain flexibility. Check gas strut mounting bolts annually and tighten if needed. With basic care, your 100R will maintain its appearance and function for 15-20 years.
The 100R installs directly onto your truck's bed rails using adjustable clamp assemblies that work with most spray-in and drop-in bed liners. We include rubber gaskets that seal against textured liner surfaces without gaps.
If you have tonneau cover rails installed, you'll need to remove them before cap installation, as the 100R's clamp system occupies the same mounting points. We recommend keeping your tonneau hardware if you plan to switch between cap and cover configurations seasonally.
The 100R can be removed by two people in approximately 15-20 minutes using basic hand tools. The clamp system uses hex bolts accessible from inside the bed, and the entire cap weighs 140-180 pounds depending on your truck model.
We recommend marking the clamp positions before removal so reinstallation aligns perfectly without adjustment. Many owners build simple A-frame storage racks in their garage to safely store the cap when not in use. Removal doesn't damage the cap or truck bed, allowing unlimited install/removal cycles.
The LEER 100R includes our 3-year limited warranty covering manufacturing defects in fiberglass construction, paint finish, glass components, and hardware. We also provide a separate 3-year warranty on all locking mechanisms and gas strut assemblies.
Warranty coverage requires professional installation by an authorized LEER dealer and normal maintenance as outlined in your owner's manual. Paint warranty excludes damage from accidents, environmental contamination, or improper cleaning products. Extended warranty options are available through participating dealers at time of purchase.
