Questions
Frequently Asked
How long does installation take?
Most TKMAUTO parts install in about one to two hours using hand tools. No drilling is required in the majority of cases — we use factory mounting points or bed-rail clamps. A printed install guide with torque specs is in every box.
Will it fit my truck?
Check the fitment box near the top of this page. Vehicle-specific parts list exact year/make/model/bed. Universal-fit parts use adjustable clamps that fit the major full-size and mid-size trucks.
What is it made of?
We build with marine-grade aluminum (does not rust) or cold-rolled steel (for load-critical parts like roll bars and bumpers) — always with a two-stage corrosion-resistant finish. See the spec grid above for exact material on this product.
Shipping and warranty?
Free U.S. shipping from our California warehouse. If it doesn't fit your truck, our California team will work with you to make it right.
