LEER 100XQ Truck Cap – Premium Commercial-Grade Topper
The LEER 100XQ represents the pinnacle of commercial truck cap engineering, combining aerospace-grade aluminum construction with enhanced security features designed for professionals who carry valuable equipment. We built this cap for contractors, tradespeople, and fleet operators who need absolute reliability in every weather condition.
Every 100XQ features a reinforced frame, integrated three-point locking system, and our proprietary weather seal technology that’s been tested in the harshest climates. The cap’s smooth exterior profile minimizes wind resistance, improving fuel economy while maintaining the rugged durability commercial operators demand. Our advanced paint process delivers a factory-matched finish that resists chipping, fading, and corrosion for years of hard daily use.

- Integrated three-point locking system with concealed hinge design
- Proprietary weather seal technology – tested to -40°F and 120°F
- Aerodynamic profile reduces drag and improves fuel efficiency
- Factory-matched automotive paint with UV-resistant clear coat
Premium aluminum construction & reinforced frame
We engineer every LEER 100XQ with a fully welded aluminum frame that eliminates the flex and stress cracks common in competitor designs. The corner posts receive additional reinforcement plates, distributing load forces across the entire structure rather than concentrating stress at vulnerable junction points.
Our manufacturing process begins with aerospace-grade 6061-T6 aluminum extrusions, chosen for their superior strength-to-weight ratio and corrosion resistance. Each frame member is precision-cut on CNC equipment, then TIG-welded by certified technicians who’ve undergone our proprietary training program. The result is a truck cap that maintains structural integrity even after years of heavy payload cycling and extreme temperature swings.
Three-point locking system & enhanced security
Professional contractors carry thousands of dollars in tools and equipment, which is why we designed the 100XQ’s locking system to exceed insurance carrier requirements for commercial vehicle security. The integrated three-point lock engages hardened steel rods at both rear corners and the centerline, creating a perimeter-secured enclosure that resists pry attacks.
Unlike padlock-dependent systems that expose vulnerable hasps, our concealed hinge design eliminates external access points entirely. The lock cylinder is recessed into the handle assembly and protected by a weatherproof boot that prevents ice buildup and corrosion. Each lock is keyed to match your truck’s ignition, eliminating the need to carry separate keys on job sites.
Factory-matched paint & finish quality
Our paint process begins with a multi-stage phosphate wash that removes all manufacturing oils and creates a chemically bonded surface for maximum paint adhesion. We then apply a two-part epoxy primer, followed by a basecoat color-matched to your truck’s factory paint code using spectrophotometer analysis.
The final step involves a high-solids urethane clear coat that’s baked at 180°F for 45 minutes. This thermal cure creates a cross-linked molecular structure that resists UV degradation, acid rain, and automatic car wash abrasion. We guarantee color-match accuracy within Delta E 1.0 – a threshold visible only under laboratory conditions.

What people are saying
Common questions about the LEER 100XQ
Yes, the 100XQ includes extended mounting brackets specifically designed for spray-in liner applications. The brackets account for the liner’s added thickness (typically 1/8″ to 1/4″) and maintain proper seal compression against the bed rail. We provide model-specific hardware for Rhino Liner, LINE-X, and other major spray-in brands.
For drop-in bed liners, you’ll need to remove the liner during installation so the cap mounts directly to the truck’s metal bed rail. This ensures proper load distribution and prevents the liner from shifting under the cap’s weight.
The 100XQ’s aluminum frame and dual-durometer seal system are engineered specifically for extreme temperature cycling. We’ve validated the design through chamber testing from -40°F to 120°F, running 10,000 thermal expansion cycles without seal failure or structural stress.
Aluminum’s thermal expansion coefficient closely matches modern truck bed steel, so the cap expands and contracts at nearly the same rate as your truck bed. This prevents the seal compression loss that plagues steel-framed caps in temperature swings. The EPDM primary seal remains pliable below zero, while the silicone secondary barrier prevents moisture migration even during rapid freeze-thaw cycles.
Yes, the 100XQ’s reinforced aluminum frame includes integrated mounting points for aftermarket roof racks and ladder racks. We offer LEER-branded rack systems that bolt directly to these factory provisions without requiring additional drilling or modification.
The cap’s roof panel is reinforced with internal crossmembers that distribute rack loads across the frame structure rather than concentrating weight at isolated mounting points. We’ve tested the roof assembly to 500 pounds dynamic load, which exceeds typical ladder and material rack requirements for commercial applications.
The 100XQ requires minimal maintenance beyond regular washing. We recommend lubricating the lock cylinder with graphite powder twice annually, and inspecting the weather seals for debris accumulation every few months. Clean the seal surfaces with mild soap and water – avoid petroleum-based cleaners that can degrade the EPDM compound.
The aluminum frame requires no rust prevention treatment, but we suggest applying automotive wax to the painted surfaces twice yearly to maintain the UV-resistant clear coat’s longevity. Check the mounting clamp tension after the first month of use, then annually thereafter. All hardware is stainless steel and requires no additional corrosion protection.
Yes, when paired with our optional front access panel, the 100XQ accommodates both fifth-wheel and gooseneck hitch installations. The access panel replaces the standard front window with a hinged assembly that opens to provide clearance for the hitch kingpin during coupling.
We engineer the access panel with the same reinforced frame construction as the main cap structure, so opening it doesn’t compromise weather sealing or security. The panel locks independently and uses the same key as your main rear door. This configuration is popular with contractors who tow equipment trailers while maintaining secure tool storage in the truck bed.
We provide a three-year warranty on the 100XQ’s paint finish against fading, peeling, and delamination under normal use conditions. This coverage includes protection against UV degradation, acid rain damage, and automatic car wash abrasion.
The warranty requires reasonable maintenance – regular washing and semi-annual waxing. It does not cover damage from accidents, chemical spills, or abrasive cleaning methods. We’ve documented 100XQ units maintaining excellent finish quality well beyond the warranty period when owners follow basic care protocols.
Yes, our paint shop can match virtually any color using spectrophotometer analysis. Provide us with your truck’s paint code or a body panel sample, and we’ll create a custom basecoat formula that matches within Delta E 1.0 color accuracy.
For custom colors, tri-coat finishes, or metallic paints, we recommend providing a physical sample rather than relying on paint codes alone. Factory paint formulas can vary slightly between production runs, and a spectrophotometer reading from your actual truck ensures perfect integration. Custom color matching adds 2-3 weeks to production time.
