Fits all 2019–2026 RAM 1500 with a 5'7" short bed — Tradesman, Big Horn, Laramie, Rebel, Limited, and TRX.
No. Clamps to your bed rails. Take it off and your truck looks stock.
Yes. Add crossbars to the T-slot rails. 850 lb static rating when parked.
Most guys finish in under 2 hours — assembly and mount included.
Yes. EPDM gaskets on every door. Tested through Canadian winters.
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.
