Frequently Asked Questions
Do these mount to factory holes or do I need to drill?
These bolt to factory rocker mounting points — no drilling required. You'll need basic hand tools and a jack to get underneath safely.
Do I need to paint or seal these before installing?
Inspect for any shipping dings or raw spots. If you plan to match your truck's finish, prep and paint before final installation. Once mounted, touch-ups are harder to access.
What hardware comes in the box?
The assembly ships ready to bolt on. Verify bolt count matches your truck's rocker configuration before you start — extended cab setups can vary slightly between model years.
