Do these mount to factory holes, or do I need to drill?

These bolt directly to factory mounting points — no drilling. Locate the factory anchor points on your rocker and you're ready to bolt down.

Will the chrome finish hold up to road salt and mud?

Chrome plating handles normal weather exposure well. Regular rinsing after winter driving or trips near saltwater keeps them looking sharp longer.

What tools and fasteners do I need to install these?

You'll need a socket set and basic hand tools. Verify bolt size and torque specs in your truck's service manual before installation.
