Ford F-150 Truck Cap by LEER
Our LEER 100XQ is the workhorse cap that F-150 owners trust for payload security and all-weather protection. This model is built with reinforced aluminum side panels and a one-piece fiberglass top shell, so your gear stays dry whether you’re hauling tools to the job site or camping gear cross-country. We engineered the 100XQ specifically for F-150 beds — 5.5-foot, 6.5-foot, and 8-foot models — with factory-style paint matching and weather seals that meet OEM standards.
The cap installs over your existing bed rails using an integrated clamp system that distributes load evenly and prevents stress cracks. Front and rear dual-action latches lock independently, and the tinted sliding side windows provide ventilation without compromising security. Whether you’re protecting expensive equipment or creating extra cargo space for family trips, the 100XQ gives you a sealed, lockable enclosure that looks like it rolled off the assembly line with your truck.
What makes this F-150 cap different
Construction and Weather Protection
We build the 100XQ with a hybrid construction method that pairs the strength of aluminum side panels with the seamless finish of a fiberglass top. The side panels resist dents and scratches during loading, while the one-piece top eliminates the seams where water typically leaks in cheaper caps. Every edge is sealed with EPDM rubber gaskets that compress against your bed rails, creating a barrier that keeps dust and moisture out even in highway rain.
The cap’s frame uses extruded aluminum rails that bolt directly to your F-150’s stake pockets, distributing weight across the bed structure instead of concentrating stress at a few points. This design prevents the cracking and warping you’ll see in caps that rely on surface-mounted clamps. We’ve tested the 100XQ at highway speeds in sustained rain and snow, and the seals hold without requiring constant adjustment or replacement.
Sizing and Bed Compatibility
Exact Fit for Your F-150 Bed
The 100XQ is manufactured in three bed lengths to match Ford’s SuperCab and SuperCrew configurations. The 5.5-foot model fits 2015-newer SuperCrew cabs, the 6.5-foot fits SuperCab trucks from 2009-forward, and the 8-foot model covers older SuperCab and regular-cab F-150s. Each cap is cut to the exact bed dimensions, so the rear door sits flush with your tailgate when closed and the front edge aligns with your cab’s rear window.
Clearance and Height
Interior height measures 19 inches at the front edge and tapers to 16 inches at the rear, following the bed’s natural slope. This gives you enough clearance for stacked toolboxes or a spare tire while keeping the cap’s profile low enough to fit in most residential garages. If you need more vertical space for taller loads, we recommend the 180XQ model, which adds 6 inches of interior height with a raised roofline.
Installation and Hardware
The 100XQ installs using a rail-mount clamp system that slides over your truck’s bed rails and tightens with stainless steel bolts. Most owners complete installation in 30-45 minutes with a socket wrench and a helper to position the cap. We include all mounting hardware, pre-cut weather stripping, and color-matched front and rear seals in the box.
Once the cap is clamped down, you’ll secure the front edge with two rubber-coated j-hooks that prevent forward movement during braking. The rear door hinges use continuous piano-style hinges that support the full width of the door, so it won’t sag or bind over time. We route the wiring for the LED dome light through a grommet in the driver-side front corner — you can tap into your truck’s dome light circuit or run it to a separate switched power source.

Common Questions About Your F-150 Truck Cap
The LEER 100XQ fits 2009-newer Ford F-150 models in all three bed lengths. For SuperCrew cabs (four full doors), you’ll need the 5.5-foot or 6.5-foot model depending on your bed. SuperCab trucks (smaller rear doors) use the 6.5-foot or 8-foot cap. If you’re ordering online, verify your bed length by measuring from the inside of the bulkhead to the inside of the tailgate — Ford’s specs list bed length as the exterior measurement, which can cause confusion.
Caps manufactured before 2015 may require minor trimming for trucks with Ford’s integrated tailgate step, but LEER updated the mold that year to accommodate the step’s contour. Check with your dealer to confirm your truck’s build date and any special features that might affect fitment.
The 100XQ’s fiberglass top is not rated for roof-mounted racks because the one-piece shell lacks the internal reinforcement needed to distribute load safely. If you need to carry ladders, kayaks, or rooftop cargo, we recommend the LEER DCC model, which is built with embedded aluminum crossbars rated for up to 300 pounds.
Some owners install aftermarket racks that clamp to the cap’s drip rails, but we don’t warranty the cap against cracking or delamination if you exceed the shell’s weight limit. For occasional light loads like a canoe or small cargo box, distribute the weight with foam padding between the rack feet and the cap surface.
When you order a 100XQ, provide your truck’s paint code (found on the driver-side door jamb sticker) and we’ll spray the cap in our booth using the exact Ford paint formula. Common colors like Oxford White, Agate Black, and Ingot Silver are in stock and ship immediately. Custom colors like Rapid Red or Antimatter Blue require a special order and typically add 7-10 business days to the delivery time.
If your truck has been repainted or you can’t locate the paint code, bring a photo of your truck to a LEER dealer and they’ll use a spectrophotometer to analyze the color and create a custom mix. The cap arrives with a clear coat applied, so it matches your truck’s gloss level right out of the crate.
Both models share the same side panel construction and bed-rail mounting system. The 100XQ has fixed side windows and a top-hinged rear door, while the 100R replaces the rear door with a full-width sliding window. The sliding rear window on the R model is popular with contractors who need to pass long materials (like lumber or pipe) through the bed without removing the entire cap.
The 100XQ’s solid rear door provides better security and insulation, making it the better choice if you’re storing tools or electronics overnight. If you frequently load items longer than your bed, or you want maximum airflow on hot days, the 100R’s sliding window is worth the upgrade.
A properly installed f150 truck cap typically reduces aerodynamic drag compared to an open bed, which can improve highway fuel economy by 1-2 mpg. The 100XQ’s sloped rear roofline is designed to channel air smoothly over the tailgate, reducing the turbulence that forms behind an empty bed.
Some owners report a slight decrease in city mileage due to the added weight (the cap weighs about 180 pounds), but the effect is minimal on modern F-150s with EcoBoost or V8 engines. If you’re hauling cargo that would otherwise fly around in an open bed, the cap’s enclosed design actually improves efficiency by eliminating drag from loose tarps or shifting loads.
Yes, the 100XQ is designed for removal, though you’ll need a helper because the cap weighs around 180 pounds. Loosen the six clamp bolts along each bed rail, disconnect the dome light wiring, and lift the cap straight up. Most owners store the cap on wall-mounted brackets in their garage or on sawhorses in a covered area.
Reinstallation takes about 20 minutes — position the cap over the bed rails, align the front edge with the cab, then tighten the clamps starting at the front corners and working toward the rear. The weather stripping compresses to the correct height automatically as you tighten the bolts, so you don’t need to adjust gaps or shims.
We back the 100XQ with a three-year warranty covering defects in materials and workmanship. This includes the fiberglass shell, aluminum panels, hinges, latches, and weather seals. The warranty does not cover damage from accidents, off-road use, or modifications like drilling holes for aftermarket accessories.
Paint finish is warranted for one year against fading, peeling, or color mismatch when properly maintained. Keep your receipt and register your cap online within 30 days of purchase to activate the warranty. If you have an issue, contact the dealer where you bought the cap — they’ll coordinate with LEER to send replacement parts or schedule a repair.
