Will I need new fasteners to bolt these on?

These mount at factory rocker points using existing bolt holes. Bring your own hardware to spec — your truck's service manual lists the right fastener size and torque spec.

Do the bars come pre-finished or do I need to paint them?

They arrive in black powder-coat finish — ready to bolt on without any sanding, priming, or paint work.

How do I know if these will fit my specific extended cab year?

Fitment is locked to extended cab models within that generation span. Cross-check your exact year and cab style against the product listing to confirm compatibility before checkout.
