Toyota Tundra Aluminum Truck Bed Cap with Side Windows (2007–2021, 6.5ft Bed)
Full visibility. No rust. Clamps on. Automotive-grade tinted side windows with integrated sliders — built for the 2nd-gen Tundra standard bed.
Built for the 2007–2021 Toyota Tundra, this windowed aluminum truck cap gives you natural light, ventilation, and full bed-side access — without sacrificing weather protection or security.
Once installed, your Tundra looks factory-fitted — purpose-built for the job site, the campsite, or anywhere in between.
Why Choose the Windowed Version?
Tinted Side Windows + Integrated Slider
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. Lockable for job site and trailhead security.
Flush-mount aluminum framing and UV-resistant seals complete the weathertight, low-profile build.
Gull-Wing Side Doors
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.
Dual Full-Length T-Slot Roof Rails
Full-length aluminum T-slot rails run the entire roof — strong, clean, and ready for crossbars, cargo carriers, or a rooftop tent. No drilling. Rated 450 lbs moving, 850 lbs parked.
Interior Mounting Rails
Both side walls pre-drilled. Bolt in a drawer system, shelves, or tool organizers — no modifications needed. Storage modules sold separately.
All-Aluminum. No Rust.
6000-series aluminum with EPDM gaskets on every door and window. Cold-tested in Canada. Your gear stays dry — first winter, tenth winter.
No-Drill Clamp Installation
Clamp System. Secure mounting to your 6.5ft bed without drilling holes in your truck bed rails.
Reversible. Remove it clean — your truck looks stock.
Assembly Time. 1–2 hours for assembly, 30–60 minutes for installation.

Questions
Will this fit my Tundra?
Fits all 2007–2021 Toyota Tundra (2nd Gen) with a 6.5ft standard bed — SR, SR5, Limited, Platinum, 1794 Edition, and TRD Pro.
Can I open the side windows while driving?
Yes — designed for ventilation at low speeds. Close and lock at highway speeds for full weatherproofing.
Will the slider rattle at highway speed?
No. Precision aluminum track with rubber-lined channels eliminates vibration at speed.
Can I lock the side sliders independently?
Yes. Each slider has its own lockable latch, separate from the gull-wing door locks.
Do I need to drill into my truck?
No. The clamp system secures to your bed rails — fully reversible, no permanent modifications.
Can I run a rooftop tent?
Yes. Add crossbars to the T-slot rails. 850 lb static rating when parked.
How long does installation take?
1–2 hours to assemble, plus 30–60 minutes to install on your truck.
Will my gear stay dry?
Yes. EPDM gaskets on every door and window. Tested through Canadian winters.
How does it affect my truck's payload?
At ~220 lbs, it's lighter than steel alternatives — more payload stays in the bed where it belongs.
Questions
Frequently Asked
How long does installation take?
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.
Does it come with side windows, or is it solid?
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.
Will it fit my truck?
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.
Will the aluminum rust or the powder coat fade?
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.
How does shipping and warranty work?
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.
