6 Truck Lines Supported
Ford · Toyota · GMC · Chevrolet · RAM · Jeep — year-specific fitment.
Hard shell. No rust. Clamps on. Full aluminum topper canopy built for the 2nd-gen Tundra standard bed.
Built specifically for the 2007–2021 Toyota Tundra, this aluminum truck cap delivers the strength and durability you need without the weight penalty of traditional steel toppers.
Once installed, your Tundra looks factory-fitted — purpose-built for the job site, the campsite, or anywhere in between.
Gas struts hold them open hands-free. Full reach to the front of your bed. Keyed locks on both sides, weather-sealed for all conditions.
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. Rated 450 lbs moving, 850 lbs parked.
Both side walls pre-drilled. Bolt in a drawer system, shelves, or tool organizers directly to both interior walls — no modifications needed. Storage modules sold separately.
6000-series aluminum construction with EPDM gaskets on every door. Cold-tested in Canada. Your gear stays dry — first winter, tenth winter. Corrosion resistance several times greater than steel.
Clamp System. Secure mounting to your 6.5ft bed without drilling holes in your truck bed rails.
Reversible. Can be removed without leaving permanent modifications to your Tundra.
Assembly Time. 1–2 hours for assembly, 30–60 minutes for installation.
6-piece modular design allows efficient shipping and easy assembly with basic hand tools. Individual panels can be replaced if damaged.

No. The clamp system secures to your bed rails — fully reversible, no permanent modifications.
Yes. Add crossbars to the T-slot rails. 850 lb static rating when parked.
1–2 hours to assemble, plus 30–60 minutes to install on your truck.
Crossbars, cargo carriers, bike racks, rooftop tents — anything with a standard T-slot mount. No drilling required.
Yes. Pre-drilled mounting points on both interior side walls accept bolt-on shelving, tool organizers, and gear trays. Storage modules sold separately.
Yes. EPDM gaskets on every door and window. Tested through Canadian winters 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.
