LEER 100R Truck Cap | Premium Fiberglass Bed Cover
Our LEER 100R offers a refined, low-profile silhouette that follows your truck's roofline for a factory-flush appearance. Built from vacuum-bonded fiberglass with gelcoat finish, this leer bed cap resists fading, chipping, and corrosion in all weather conditions.
The 100R is designed for truck owners who want cargo security without sacrificing style. Carpeted headliner, tinted windows, and a three-piece sliding front window come standard, while industry-leading seals keep dust and moisture out of your bed.

Fiberglass construction & durability
We build the LEER 100R from vacuum-bonded fiberglass, a manufacturing process that eliminates air pockets and creates a single-piece shell stronger than hand-laid alternatives. The gelcoat finish is applied during molding, so color runs through the entire thickness rather than sitting on the surface as paint.
This construction method delivers superior impact resistance and weather protection. The fiberglass won’t dent like aluminum, and the gelcoat won’t chip or flake over years of sun exposure. Our five-year warranty covers delamination, gelcoat cracking, and structural failures caused by manufacturing defects.
Low-profile design & cab integration
The 100R’s roofline mirrors your truck cab’s contour, creating a seamless transition from windshield to tailgate. This low-profile stance reduces wind resistance compared to taller caps, improving highway fuel economy by an estimated 8-12% in independent aerodynamic testing.
Windshield integration
Our three-piece sliding front window sits flush against the cab’s rear glass, allowing airflow into the bed while preventing rain entry. Removable bug screens snap into place behind each slider panel. The center panel locks independently, so you can ventilate the bed without compromising security.
Color matching & custom paint options
We offer the LEER 100R in over 200 OEM paint codes covering Ford, Chevrolet, RAM, Toyota, and Nissan factory colors from 2010 to current model years. Our computerized mixing system matches your truck’s paint down to the metallic flake size and clear-coat depth.
Custom colors are available through our premium paint program. Submit a paint sample or color code, and we’ll formulate a gelcoat match within two weeks. The same reinforced aluminum frame found in the LEER 100XQ and 100XL series supports roof racks rated to 500 pounds distributed weight, so you can mount kayak carriers, ladder racks, or rooftop tents without additional bracing.

Questions about the LEER 100R truck cap
Yes, the 100R is compatible with spray-in and drop-in bedliners. Our QuickClamp system adjusts to accommodate bed rail height variations up to one inch. If you have a thick drop-in liner that raises the rail significantly, contact your installer to confirm clamp compatibility before ordering.
Most Rhino, LINE-X, and Penda liners work without modification. The cap's rubber seals compress to maintain a weathertight seal even when the rail height differs slightly from factory specifications.
Locate your truck's paint code on the driver-side door jamb sticker or inside the glove box. Provide this code to your LEER dealer when ordering, and we'll mix a gelcoat match from our database of over 200 factory colors.
For custom or older paint codes not in our system, bring a painted part like a fuel door or bumper end cap to your dealer. We'll scan the color and create a custom gelcoat formula within 10-15 business days.
The 100R includes a reinforced aluminum frame rated for 500 pounds of distributed weight, supporting most aftermarket roof racks designed for truck caps. We recommend Thule, Yakima, and TracRac systems with clamp-on mounts that attach to the cap's side rails.
Avoid drilling into the fiberglass shell for rack installation, as this voids the warranty and creates potential leak points. Use rack systems specifically designed for truck caps rather than generic vehicle roof racks.
No, all three panels slide horizontally by hand and lock with thumb latches. The center panel locks independently with a twist knob, allowing you to open the side panels for ventilation while keeping the center section secured.
Removable bug screens snap into place behind each panel without tools. Store the screens inside the cap during winter months to prevent mesh damage from ice buildup.
We back the 100R with a five-year limited warranty covering fiberglass delamination, gelcoat cracking, structural failures, and hardware corrosion caused by manufacturing defects. The warranty does not cover damage from accidents, improper installation, or modifications made after purchase.
Paint fading beyond normal wear is covered for three years. Keep your original purchase receipt and installation paperwork to validate warranty claims.
The 100R weighs between 180 and 220 pounds depending on your truck's bed length. A standard 6.5-foot cap weighs approximately 195 pounds, while an 8-foot cap weighs around 215 pounds.
Two adults can lift and position the cap during installation, though we recommend three people for easier alignment. The QuickClamp system allows one person to secure the cap once it's positioned on the bed rails.
No, the 100R replaces your tonneau cover entirely. You'll need to remove any existing bed cover before installation. The cap provides superior cargo security and weather protection compared to soft or folding tonneau covers, with lockable side windows and a reinforced rear door.
If you want the option to switch between an open bed and covered bed, consider a removable tonneau system instead. The 100R is designed for permanent or semi-permanent installation.
