ARE Aluminum Truck Cap – Premium Lightweight Protection
Our aluminum truck cap represents decades of engineering expertise in lightweight bed protection. We built this cap for truck owners who refuse to compromise between strength and efficiency.
Every panel is precision-formed from marine-grade aluminum alloy, creating a weather-tight shell that weighs 40% less than comparable fiberglass models. The aircraft-style rivet construction delivers a lifetime of service while maintaining your truck's payload capacity and fuel economy. Powder-coated finish options match every major truck manufacturer's color palette.
- Marine-grade aluminum alloy construction resists corrosion in salt and moisture environments
- Weighs 40% less than fiberglass equivalents – preserves payload capacity
- Aircraft-style riveted seams provide superior structural integrity
- Powder-coated finish available in 12 OEM-matched colors
- Carpeted headliner with LED dome lighting included
Aluminum construction advantages
We chose aluminum for our truck caps because physics doesn’t negotiate. A full-size aluminum truck cap weighs between 110-140 pounds depending on bed length, while fiberglass alternatives routinely exceed 200 pounds. That weight difference translates directly to better fuel economy and increased payload capacity.
The material’s natural corrosion resistance means our caps survive decades of exposure without the gel-coat cracking and UV degradation common in composite materials. Aluminum forms a protective oxide layer immediately upon exposure to oxygen, creating a self-healing barrier against rust. Contractors working near saltwater or in snow-belt states see this benefit within the first winter season.
Installation and truck compatibility
We manufacture our aluminum caps with truck-specific mounting systems for every major full-size platform. Ford, Chevy, RAM, GMC, Toyota, and Nissan trucks from 2000-forward have dedicated mounting rails that attach directly to factory stake pockets and bed bolt locations.
Installation requires no drilling on most applications. Our C-channel clamp system distributes clamping force across eight contact points, eliminating the stress concentrations that crack bed rails. Two people can safely install a cap in 20-30 minutes using basic hand tools. We include all mounting hardware, rubber bed rail gaskets, and a torque specification chart with every cap.
Window systems and ventilation
Every aluminum truck cap leaves our facility with frameless tempered glass windows on three sides plus a sliding front window for cab access. We use the same glass tempering process that automotive manufacturers specify for side windows – four times stronger than standard annealed glass and designed to fragment into small granules rather than jagged shards if broken.
The sliding front window features a dual-track system with separate screens. You can slide the glass panel independently of the screen for ventilation without bug intrusion, or remove both panels completely for maximum airflow during summer months. Tinted glass options reduce interior heat buildup by 35% compared to clear glass in direct sunlight.

What people are saying
Common questions about our aluminum truck caps
Our aluminum truck caps weigh between 110-140 pounds depending on your bed length. A 5.5-foot short bed cap weighs approximately 110 pounds, a 6.5-foot standard bed weighs around 125 pounds, and an 8-foot long bed weighs about 140 pounds.
This represents 40% less weight than comparable fiberglass models. The reduced weight preserves your truck's payload capacity and improves fuel economy by an average of 1-2 MPG compared to heavier cap alternatives.
Marine-grade aluminum naturally resists corrosion through a self-healing oxide layer that forms immediately upon air exposure. Our caps use the same alloy specifications found in offshore marine applications where saltwater exposure is constant.
The powder-coated finish provides additional protection against environmental factors. We warranty our aluminum caps against corrosion perforation for the life of your vehicle ownership. Customers in coastal and snow-belt regions report zero corrosion issues even after five-plus years of service.
Our aluminum truck cap is light enough that two people can safely remove and reinstall it in about 15 minutes using the factory clamp system. One person can technically handle it alone on short-bed models that weigh 110 pounds, though we recommend having a helper to avoid awkward lifting angles.
The C-channel clamps require only a socket wrench to loosen and tighten – no drilling or permanent modifications to your truck bed. Many customers remove their caps seasonally to switch between secure storage in winter and open-bed capacity during summer construction projects.
We provide a limited lifetime warranty against structural failure and corrosion perforation for as long as you own your truck. This covers the aluminum panels, frame assembly, and rivet joints against manufacturing defects and material degradation.
The warranty also includes three years of coverage on windows, locks, hinges, and gas struts. Paint and powder-coat finish are warranted for three years against fading, peeling, or chalking under normal use conditions. Commercial fleet applications receive modified warranty terms based on annual mileage.
Adding an aluminum truck cap does not reduce your truck's rated towing capacity. Towing capacity is determined by your vehicle's frame, engine, transmission, and axle specifications – not by cargo weight in the bed.
However, the cap's 110-140 pound weight does count toward your payload capacity, which is separate from towing. If your truck has a 2,000-pound payload rating, the cap leaves you with 1,860-1,890 pounds of remaining bed capacity. This rarely impacts real-world use since most towing scenarios involve minimal bed cargo.
We offer powder-coating in 12 factory-matched colors for Ford, Chevrolet, RAM, GMC, Toyota, and Nissan trucks at the time of order. Powder coating is applied before assembly and provides superior durability compared to spray paint.
If you need a custom color match for an older truck or aftermarket paint job, the cap can be professionally painted using standard automotive paint systems. The aluminum surface accepts paint excellently after proper preparation. Many body shops are familiar with painting our caps and can color-match to your truck's existing finish.
Our caps include a sliding front window with an independent screen track that allows airflow between the truck cab and cap interior even when the glass is closed. This creates natural convection that prevents moisture buildup and keeps interior temperatures closer to ambient.
For additional ventilation, we offer optional side vents that mount in the forward corners of the cap. These vents use a louver design that allows air movement while blocking rain entry. The combination of front window and side vents provides adequate airflow for most climates without requiring powered ventilation systems.
