Frequently Asked Questions
Do these bolt directly to the truck or do I need to drill holes?
They mount at factory rocker points — no drilling needed. Bolt-on install using existing holes on the frame.
Will I need to paint these or do they come ready to install?
These ship in raw steel finish. Plan on light surface prep and a coat of your choice before install to prevent rust, or powder coat them for a finished look.
What tools do I need to install these myself?
Basic hand tools — socket set, wrenches, and a jack. No special equipment required. Refer to your vehicle's service manual for torque specs on the frame bolts.
