LEER Modular Truck Cap – Customizable Storage & Security
Our LEER modular truck cap redefines versatility for full-size pickups. Built on an all-aluminum frame with reinforced composite side panels, this cap transforms your truck bed into a secure, weatherproof workspace. Configure up to six accessory mounting points for roof racks, ladder racks, interior LED strips, and sliding side windows—all without drilling.
Designed for contractors, outdoor enthusiasts, and fleet operators who demand adaptability, the modular truck cap features quick-release clamps that install in under 20 minutes. The dual-locking rear door with integrated gas struts ensures smooth operation and theft deterrence. Every cap ships with color-matched automotive paint and a limited lifetime warranty on structural components.

Modular Design & Accessory Integration
The LEER modular truck cap features six factory-installed mounting points along the roof and side rails, eliminating the guesswork of aftermarket installations. Mount a Thule or Yakima roof rack system using the forward and aft anchor points rated for 165 pounds dynamic load. Side-rail T-slots accept LED light bars, utility hooks, and interior shelving without compromising the cap’s structural integrity.
We machine every mounting port with corrosion-resistant stainless steel inserts and include rubber grommets to prevent water intrusion. The rear door accepts optional third-party vents and secondary locks. Our design team tested 47 accessory configurations during development to ensure compatibility with leading truck bed organizers and cargo management systems.
Installation & Bed Compatibility
Quick-Release Clamp System
Our patented quick-release clamps secure the modular truck cap to factory bed rails in 20 minutes using standard hand tools. Eight stainless steel clamps distribute clamping force evenly across the perimeter, preventing stress concentration that causes warping in traditional bolt-through designs. Adjustable height brackets accommodate spray-in bed liners up to 0.25 inches thick without custom modifications.
The cap fits Ford F-150, Chevy Silverado 1500, Ram 1500, Toyota Tundra, and Nissan Titan models from 2015-present with 5.5-foot, 6.5-foot, or 8-foot beds. We maintain dimensional tolerances within ±2mm to ensure flush alignment with cab profiles. For older trucks or custom bed modifications, contact our technical support team for compatibility verification.
Weather Sealing & Durability
Every LEER modular truck cap undergoes pressure testing equivalent to highway speeds in freezing rain. We use marine-grade EPDM rubber gaskets along all sealing surfaces, bonded with 3M automotive adhesive rated for temperatures from -40°F to 250°F. The composite side panels resist UV degradation, stone chips, and chemical exposure from road salt and agricultural materials.
Our powder-coat finish process applies two layers of automotive-grade paint over zinc-phosphate primer for maximum chip resistance. The rear door’s triple-seal design—perimeter gasket, threshold sweep, and latch compression seal—prevents dust infiltration in desert environments and moisture in coastal climates. We back this with a 3-year finish warranty and lifetime structural coverage.

Modular Truck Cap Questions
Our LEER modular truck cap fits Ford F-150, Chevy Silverado 1500, Ram 1500, Toyota Tundra, and Nissan Titan models from 2015 to present. We manufacture caps for 5.5-foot, 6.5-foot, and 8-foot bed configurations. During checkout, select your truck's year, make, model, and bed length to ensure proper fitment.
The adjustable clamp system accommodates spray-in bed liners up to 0.25 inches thick without modifications. For older truck models or custom bed modifications, contact our technical team with your truck's VIN for compatibility verification.
Installation takes approximately 20 minutes using the included quick-release clamp system and standard hand tools. The cap weighs 110 pounds for short-bed models and 135 pounds for long-bed models, so we recommend two people for safe handling.
Eight stainless steel clamps secure the cap to your truck's factory bed rails without drilling or permanent modifications. Removal requires loosening the clamps with a ratchet wrench—the entire process reverses in under 15 minutes. Detailed installation videos and printed instructions ship with every cap.
The cap features six pre-drilled accessory ports along the roof and side rails, compatible with Thule, Yakima, and Rhino-Rack roof systems. The T-slot side rails accept LED light bars, utility hooks, interior shelving, and cargo nets without drilling additional holes.
Maximum roof load capacity is 165 pounds dynamic (while driving) and 300 pounds static (parked). The rear door accepts third-party vents, secondary locks, and ladder stops. We provide rubber grommets and stainless steel inserts with every mounting port to prevent water intrusion and corrosion.
Every LEER modular truck cap undergoes pressure testing equivalent to 70 mph in freezing rain before leaving our facility. We use marine-grade EPDM rubber gaskets along all sealing surfaces, rated for temperatures from -40°F to 250°F.
The rear door features a triple-seal design with perimeter gasket, threshold sweep, and latch compression seal. Customers report successful pressure washing and automated car wash use without leaks. Our weatherproofing carries a 3-year warranty covering seal integrity and water intrusion issues.
All LEER modular truck caps ship with automotive-grade powder coat in common truck colors: black, white, silver, and gray. For exact OEM color matching, select our Custom Color Match Service during checkout. We match over 200 Ford, GM, Toyota, Ram, and Nissan factory paint codes using a two-stage powder coat process.
Custom color orders add 7-10 business days to production time. We apply zinc-phosphate primer followed by two layers of color-matched powder coat for chip resistance. The finish carries a 3-year warranty against fading, peeling, and oxidation.
The LEER modular truck cap includes a limited lifetime warranty on the aluminum frame and structural components against defects in materials and workmanship. The powder coat finish carries a 3-year warranty covering fading, peeling, and corrosion.
Gas struts, locks, and weatherstripping are warranted for 3 years from the original purchase date. The warranty transfers to subsequent owners if you sell your truck. Claims require proof of purchase and photos documenting the issue. We cover replacement parts and shipping for valid warranty claims.
The dual-locking rear door system uses a rotary paddle lock with internal deadbolts that extend 1.5 inches into reinforced strike plates on both side rails. Stainless steel latch pins resist pry-bar attacks and cutting tools.
For fleet applications, we offer keyed-alike cylinders compatible with your truck's OEM door locks, eliminating the need for multiple keys. The cap's aluminum frame and composite panels resist forced entry better than fiberglass designs. Optional third-party alarm systems integrate with the interior courtesy light circuit for motion-sensing capabilities.
