6 Truck Lines Supported
Ford · Toyota · GMC · Chevrolet · RAM · Jeep — year-specific fitment.
Built for work and adventure — automotive-grade tempered glass, integrated side sliders, and gull-wing access in a lightweight aluminum build.
Built for the 2015-2025 Ford F-150, this aluminum truck cap delivers the strength and durability you need without the weight penalty of traditional steel toppers.
Once installed, your F-150 looks factory-fitted — purpose-built for the job site, the campsite, or anywhere in between.
Full-panel automotive-grade tempered glass on every side door — wide-view, impact-resistant, and tinted for privacy without sacrificing natural light. An integrated slider panel opens on demand for direct bed-side access or ventilation — no need to open the rear door.
Lighter than steel. Tougher than fiberglass. Won't rust, won't crack — built to outlast your truck.
Full-panel automotive-grade tempered glass spans each side door — wide-view, impact-resistant, and tinted for privacy without sacrificing natural light.
An integrated slider panel opens on demand for direct bed-side access or ventilation — no need to open the rear door. Lockable for job site and trailhead security.
Flush-mount aluminum framing and UV-resistant seals complete the weathertight, low-profile build.
Full-length aluminum T-slot rails run the entire roof — strong, clean, and ready for crossbars, cargo carriers, or a rooftop tent. No drilling. Compatible with most universal T-slot systems.
Factory pre-drilled side walls let you mount shelving units, tool organizers, or gear trays directly to both interior walls — no modifications needed. Storage modules sold separately.
Easy Access. Large gull-wing side doors with tinted tempered glass windows and gas struts allow full access to the front of your truck bed.
Lockable System. Each door has weather-sealed locks with a unified key system for security.
Clamp System. Secure mounting to your 5.5ft bed without drilling holes in your truck bed rails.
Reversible. Can be removed without leaving permanent modifications to your F-150.
Flat-Pack Shipping. 6-piece modular design allows efficient shipping and assembly with basic hand tools.
Assembly Time. 1-2 hours for assembly, 0.5-1 hour for installation to truck bed.
Replaceable Panels. Individual panels and windows can be replaced if damaged.
Static Load (Parked). 850 lbs (385 kg) — Rooftop tent compatible when parked.
Dynamic Load (Moving). 450 lbs (205 kg) — Safe load capacity while driving.
Weather Sealing. A multi-point sealing system with precision-fitted EPDM gaskets around all windows and doors creates a fully enclosed, weather-tight interior — keeping cargo dry through heavy rain, car washes, and prolonged moisture exposure.
Rust-Resistant Build. High-strength aluminum alloy construction delivers corrosion resistance several times greater than steel, eliminating rust at the structural level and standing up to road salt, snow, and harsh seasonal cycles.
Cold-Weather Tested. Validated in extreme cold across Canada, maintaining full seal integrity and structural performance in sub-zero temperatures — built for year-round reliability in the most demanding climates.

Yes — designed for ventilation at low speeds. Close and lock at highway speeds for weatherproofing.

Yes. A multi-point EPDM sealing system on all windows and doors, combined with an all-aluminum rust-proof structure, keeps water and dust out in all conditions.
At ~190 lbs, it's lighter than steel alternatives — more payload stays in the bed where it belongs.
Most customers complete the install in 75–90 minutes with two people. No drilling is required — the cap secures to your existing bed rail holes with our stainless clamp kit. A printed install guide with torque specs is in the box.
We build both versions on the same 6061-T6 aluminum shell — same load rating, same bolt-on install. The difference is only the side panels:
Windows — tempered sliding glass on the driver and passenger sides. Better for overlanding, camping, pets, or any time you want airflow and outward visibility.
Solid — fully enclosed aluminum panels. Better for job-site tool security or gear you want out of sight and keyed-locked.
This cap is cut for the specific year, make, model, and bed length listed in the fitment box at the top of the page. If your truck matches that spec, the cap is engineered to bolt right on. Short-bed and long-bed versions are not interchangeable.
The shell is 6061-T6 aluminum — corrosion resistance is inherent to the material, so the structure won't rust. The exterior is finished in powder-coated black for UV protection. Even if the powder-coat gets scuffed at a job site, the aluminum underneath stays sound. The shell is backed by our lifetime structural warranty.
Free freight shipping in the continental US, from our California warehouse via LTL carrier. Delivery requires a signature; the carrier will schedule a window once it reaches your local terminal.
The aluminum shell carries a lifetime structural warranty against defects in material and workmanship. Glass, gaskets, locks, and gas struts carry a 1-year warranty. Fitment support is direct from our California team.
