Rivian R1T
Aluminum Truck Bed Cap
Hard shell truck topper. Lightweight. No-drill. Built for electric.
Full aluminum truck bed cap purpose-built for the 2022–2026 Rivian R1T electric pickup truck.
The R1T is unlike any other truck — and your truck cap should match. 6000-series aluminum keeps weight minimal so your range stays maximal. No-drill clamp system preserves the R1T’s clean lines and leaves zero permanent marks. Solid aluminum side panels for maximum security and weather protection.
Why Aluminum for Your R1T?
Weight Matters on an EV
Every pound counts on an electric truck. Our 6000-series aluminum cap weighs significantly less than steel alternatives — protecting your range while protecting your gear. Lighter than fiberglass. Stronger than plastic. Built to last as long as your R1T.
No-Drill. No Damage. No Regrets.
The R1T’s bed rails are precision-engineered. Our clamp system attaches without drilling a single hole — your truck stays factory-clean. Remove it in 30 minutes and it looks like it was never there.
Features
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. Works alongside the R1T’s existing bed storage access.
T-Slot Roof Rails
Dual full-length tracks, front to back. Mount crossbars, a rooftop tent, or a cargo basket — anything T-slot compatible. 450 lbs dynamic. 850 lbs static.
Interior Mounting Rails
Both side walls pre-drilled. Bolt in a drawer system, shelves, or tool organizers. No drilling required. Modules sold separately.
All-Aluminum. No Rust.
6000-series aluminum construction with EPDM gaskets on every door. Cold-tested in Canada. Your gear stays dry — first winter, tenth winter.
No-Drill Clamp Install
6-piece flat-pack. Assemble in 1–2 hrs. Clamp to your bed rails in 30 min. Remove it clean — your R1T looks stock.

FAQ
Will this truck bed cap fit my Rivian R1T?
Yes. Designed specifically for the 2022–2026 Rivian R1T with its 4.5 ft (54 in) bed — Adventure, Explore, Launch Edition, Quad-Motor, and Dual-Motor configurations.
Will this affect my R1T’s range?
Aluminum is significantly lighter than steel alternatives. We’ve minimized weight without compromising strength — the impact on range is minimal compared to heavier topper options.
Does it interfere with the R1T’s gear tunnel or pass-through storage?
The cap covers the open bed area. The R1T’s gear tunnel (front of bed) and pass-through storage remain accessible via the gull-wing side doors. We recommend confirming clearance with your specific configuration before ordering.
Do I need to drill into my R1T?
No. The clamp system attaches to your bed rails without drilling. Remove it and your R1T looks completely stock — no holes, no marks.
Can I mount a rooftop tent?
Yes. Add crossbars to the T-slot roof rails. 850 lb static load rating when parked.
How long does installation take?
Most installs are done in under 2 hours — assembly and mounting included.
Will my gear stay dry?
Yes. EPDM gaskets seal every door. Tested through Canadian winters.

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. If you ever have a structural concern, contact us at info@tkmauto.com and we'll work with you directly.
How does shipping 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. A phone number is required at checkout so the freight carrier can reach you to schedule delivery.
Built with 6061-T6 aluminum shell and stainless steel hardware. If you ever have a structural concern with your cap, contact us at info@tkmauto.com and our California team will work with you directly.
