Will this bolt to the factory rocker panel holes?

Yes. This mounts at factory rocker attachment points — no drilling or welding needed. Use the existing holes and fasteners appropriate for your vehicle's frame.

Do I need to prime or paint this before installation?

That's your call. The bar ships unpainted — you can install it as-is or prep and paint it to match your truck. Apply primer and topcoat if you want a finished look.

Is there a return window if it doesn't fit?

Test-fit before permanent mounting. If it's not right for your setup, contact ModSupply within 30 days of purchase to discuss options.
