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 a solid shell?
The TKMAUTO bed cap is a solid aluminum shell — no side windows. This keeps the structure stiff, the interior dark for gear security, and the weight down. If you need a window version, contact us for a custom build.
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 powder coat rust, fade, or chalk in the sun?
No. The shell is marine-grade 5052 aluminum (which does not rust), and the powder-coat is UV-stabilized automotive grade — the same process used on Rough Country and ARB components. We back the finish with our lifetime structural warranty.
How does shipping and warranty work?
Free shipping to all 50 U.S. states. Every order ships from our California warehouse via freight carrier. Every bed cap carries our lifetime structural warranty, with fitment support direct from our California team.
