LEER Truck Topper – Premium Fiberglass Caps for Work & Adventure

★★★★★4.8/5· thousands of reviews

The LEER 100XQ represents our most popular fiberglass truck cap, combining aerodynamic styling with legendary durability. We engineered this topper with a low-profile design that complements modern truck lines while maximizing interior headroom.

Every 100XQ features one-piece construction for superior weather sealing, eliminating the leaks common in multi-piece designs. The fiberglass shell resists dents, rust, and UV degradation, maintaining its appearance for decades. We include tinted sliding side windows with screens, a rear door with automotive-grade weatherstripping, and a custom-matched factory paint finish.

Ideal for tradespeople who need secure storage and weekend adventurers alike, the 100XQ transforms your truck bed into a protected cargo area. Installation takes under an hour using our integrated clamp system that requires no drilling.

Fiberglass Construction & Weather Sealing

Fiberglass Construction & Weather Sealing

Every LEER topper begins with hand-laid fiberglass composite, a material we’ve refined over five decades of manufacturing. Our one-piece shell construction eliminates the seams and joints that cause leaks in aluminum caps.

We apply multiple layers of marine-grade gelcoat, then cure each shell in controlled climate chambers to prevent warping or cracking. The result is a rigid structure that maintains its seal through temperature extremes, highway speeds, and off-road conditions. Automotive-grade weatherstripping lines every opening, creating compression seals that block rain, snow, and dust.


Interior Features & Cargo Management

Interior Features & Cargo Management

Lighting & Visibility

We install LED dome lights with three-position switches in every topper, providing instant illumination when you open the rear door. Tinted side windows allow natural light while maintaining cargo privacy and reducing interior heat buildup.

Accessory Integration

Our reinforced roof panels support roof racks, kayak carriers, and rooftop tents without additional reinforcement. Interior mounting tracks accept shelving systems, tie-down anchors, and custom dividers. We pre-wire select models for aftermarket accessories, simplifying installation of work lights, power inverters, and tool organizers.


Sizing & Vehicle Compatibility

Sizing & Vehicle Compatibility

LEER toppers fit virtually every full-size and mid-size pickup manufactured since 1985. We maintain over 200 unique molds to ensure precise fitment for Ford, Chevrolet, GMC, Ram, Toyota, and Nissan trucks.

Measure your truck bed from inside the bulkhead to inside the tailgate to determine your bed length. Standard sizes include 5.5-foot short beds, 6.5-foot standard beds, and 8-foot long beds. Our sales team verifies your exact truck year, make, model, and bed configuration before manufacturing your custom topper.

Perfect fit on my 2022 F-150
I ordered the 100XQ for my F-150 and the color match is flawless. Installation took about 40 minutes with my son helping. We've had heavy rain and zero leaks. The sliding side windows are a great feature I use constantly.

Best investment for my work truck
I've had the LEER 180 on my Silverado for three years now. It's been to job sites in every weather condition and still looks like new. The security gives me peace of mind leaving tools overnight. Worth every penny.

Quieter than I expected
I was worried about wind noise on the highway but the aerodynamic design is impressive. I cruise at 75 mph and barely notice it's there. The improved gas mileage compared to my old aluminum cap was a nice surprise too.

Game changer for camping trips
We mounted a rooftop tent on the reinforced roof and use the interior for all our gear. The weatherproofing is excellent even in mountain storms. The dome light is bright enough for organizing equipment at night.

Superior quality and craftsmanship
I compared several brands before choosing LEER. The fiberglass construction and attention to detail are evident immediately. The paint finish is indistinguishable from my truck's factory paint. Very impressed with the build quality.

Easy on and off when needed
I occasionally need to haul tall equipment so I remove my 100XQ a few times a year. The clamp system makes this simple with just two people. Reinstallation takes 20 minutes and everything seals perfectly again.

Common Questions About LEER Truck Toppers

LEER manufactures toppers for specific truck makes, models, years, and bed lengths. You'll need your truck's exact year, make, model, cab configuration, and bed length measurement.

Measure from the inside of your bed at the bulkhead to the inside of your tailgate to determine bed length. Common sizes are 5.5 feet, 6.5 feet, and 8 feet. Our dealers use this information to order the correct mold and mounting hardware for your specific truck.

Every LEER topper is custom-painted to match your truck's factory color code before shipping. We use computerized color-matching and apply the same multi-stage painting process your truck manufacturer uses.

The paint finish comes with a three-year warranty and includes UV-protective clear coat. If you repaint your truck later, professional auto body shops can repaint the topper using standard automotive techniques since it's the same fiberglass and paint system.

Most LEER fiberglass toppers weigh between 150 and 200 pounds depending on size and model. The 100XQ typically weighs 160-180 pounds, while heavier commercial models like the 180 can reach 200-220 pounds.

Two adults can lift and install a topper without special equipment. The weight is well within your truck's payload capacity and has minimal impact on fuel economy due to the aerodynamic design.

LEER toppers feature one-piece fiberglass construction with no seams or joints where water can penetrate. We seal every opening with automotive-grade weatherstripping that creates compression seals when doors and windows close.

The front bulkhead includes a formed seal that compresses against your truck's cab. While no topper is 100% waterproof in extreme conditions, LEER caps provide excellent weather protection that keeps cargo dry in rain, snow, and car washes when properly installed and maintained.

Yes, LEER toppers feature reinforced roof panels designed to support aftermarket roof rack systems. The fiberglass structure can handle kayaks, cargo boxes, rooftop tents, and ladder racks without additional reinforcement.

We recommend using rack systems specifically designed for truck cap installation with mounting feet that distribute weight across the roof. Most racks attach using the cap's rain gutters or through-bolted mounting points. Check your specific model's weight capacity in the owner's manual.

The universal clamp system allows removal with basic hand tools. Loosen the clamp bolts around the perimeter, then lift the topper straight up with a second person helping.

Most owners remove their toppers once or twice a year for hauling tall items. The process takes about 15 minutes to remove and 30 minutes to reinstall. Store the topper on padded sawhorses or hanging wall brackets to protect the finish when not in use.

LEER provides a limited lifetime warranty on the fiberglass shell against structural defects, cracks, and delamination. This warranty is transferable to subsequent owners if you sell your truck.

Paint finish, glass, locks, hinges, and weatherstripping carry a three-year warranty from the date of purchase. We maintain parts inventory for models dating back 30 years, ensuring long-term serviceability even after the warranty period expires.
