LEER 100R Truck Cap – Sleek Profile with Raised Roofline
The LEER 100R delivers a raised roofline that adds interior height without compromising the sleek profile pickup owners love. We engineered this cap with a one-piece fiberglass construction for maximum durability and weather resistance, so your cargo stays protected season after season.
Every 100R features frameless, dark-tinted side windows that enhance visibility while reducing glare, and our signature wraparound rear door provides full access to your truck bed. This cap fits flush with your truck's cab and is available in factory-matched paint colors, blending seamlessly with your vehicle's original finish.
100R Construction & Design
Fiberglass Shell & Paint Finish
We build the 100R from a single piece of compression-molded fiberglass, eliminating seams that can crack or leak over time. This manufacturing process creates a shell strong enough to support roof-mounted cargo carriers while maintaining a lightweight profile that won’t strain your truck’s suspension.
Our factory paint-matching service uses your vehicle’s color code to mix automotive-grade paint that precisely matches your truck’s finish. We apply multiple coats in a controlled environment before curing under infrared lamps, ensuring a glossy finish that resists UV fade and road chemicals. The result is a cap that looks factory-installed from every angle.
Raised Roof Design & Interior Space
Why the Raised Roofline Matters
The 100R’s raised roof adds four inches of clearance compared to standard caps, giving you room to stand larger toolboxes upright or stack camping gear without compressing soft items. We designed the roof curve to minimize wind resistance, so you won’t see dramatic fuel economy drops on highway drives.
Inside, the added height makes loading and unloading cargo easier on your back. You can reach items at the front of the bed without crawling, and the extra vertical space accommodates wheeled coolers or standing tackle boxes that won’t fit under low-profile caps.
Window Configuration & Rear Access
Frameless side windows on the 100R slide open independently for ventilation without exposing your entire cargo area. We tint the glass dark enough to keep prying eyes away from valuable tools and equipment, while still allowing you to see out when backing up or changing lanes.
Our wraparound rear door swings open on marine-grade hinges rated for 50,000 cycles. The three-point locking system engages at the top, side, and bottom of the door frame, creating a weather-tight seal that keeps rain and dust out even during off-road trips. A gas strut holds the door open at a 90-degree angle, so you can load heavy items without the door slamming shut.

Common Questions About the 100R
Yes, the 100R works with most spray-in bed liners including Line-X and Rhino Linings. Our mounting clamps adjust to accommodate the added thickness of spray liners, typically up to a quarter inch. You may need slightly longer mounting bolts, which your installer can provide during setup.
If you have a drop-in plastic bed liner, you'll need to remove it before installation since the cap mounts directly to your truck's bed rails. The fiberglass shell creates its own protective barrier, so most customers find they don't need an additional liner once the cap is installed.
The 100R weighs between 180 and 220 pounds depending on your truck's bed length. Short bed models (5-6 feet) are lighter, while long bed versions (8 feet) are at the upper end of that range. Two people can lift and position the cap during installation, though most professional installers use overhead hoists for precise alignment.
The fiberglass construction keeps weight lower than comparable aluminum caps while maintaining superior strength and weather resistance.
The 100R includes factory mounting points for LEER roof racks and crossbars. We reinforce these areas during manufacturing to handle up to 300 pounds of evenly distributed cargo. You can mount ladder racks, kayak carriers, or cargo boxes directly to these points without drilling additional holes.
Third-party racks may require custom mounting solutions. We recommend using LEER-approved accessories to maintain your warranty coverage and ensure proper load distribution across the fiberglass roof.
The 100R features a raised roofline that adds four inches of interior height, while the 100XQ sits lower for a more aerodynamic profile. Both use the same fiberglass construction and locking systems, but the 100R gives you extra vertical cargo space at the cost of slightly increased wind resistance.
Many customers who haul toolboxes or camping gear prefer the 100R's added clearance, while those prioritizing fuel economy and a sleeker look choose the 100XQ. Both models are among the most popular leer toppers we manufacture.
The 100R does not include interior lighting as standard equipment, but we offer LED lighting kits as dealer-installed accessories. These kits wire into your truck's cargo light circuit and mount to the cap's interior roof, providing hands-free illumination when you open the rear door.
Many customers also install battery-powered LED strips as an aftermarket option. The smooth interior surface makes it easy to mount adhesive-backed lighting wherever you need it.
Wash your 100R with the same car wash soap you use on your truck, then dry with a microfiber towel to prevent water spots. We recommend waxing the cap every three to six months using automotive paste wax, which protects the finish from UV damage and road salt.
Avoid automatic car washes with harsh brushes that can scratch the paint. If you notice any chips from road debris, touch them up promptly with factory-matched paint to prevent moisture from penetrating the fiberglass.
You can expect a 1-2 MPG reduction in highway fuel economy due to the added wind resistance of any truck cap. The 100R's raised roof creates slightly more drag than low-profile models, but our aerodynamic design minimizes the impact compared to older box-style caps.
Most customers find the fuel cost is offset by the ability to secure cargo and eliminate the need for separate storage solutions. City driving and stop-and-go traffic show minimal fuel economy changes.
