Do these require fasteners, or are they bolted at factory points?

They mount at factory rocker points using existing holes — no drilling needed. Bring basic hand tools and your torque wrench. Hardware not included; you'll use your truck's factory fasteners or pick up grade 8 bolts to spec.

Can I drive on these bars to reach the roof, or are they just a step?

They're designed as a running board and approach step for cab entry. Test-fit and inspect your mounting before heavy use. If you plan to stand full weight on them during ladder work, confirm installation torque and contact our support line to verify load rating for your application.

Do I need to paint or seal these before installation?

Raw aluminum can oxidize over time. You can install first and finish later, or prep with a light sanding and spray primer before mounting — either way works. If you're in a high-salt environment, primer and paint will extend life significantly.
