Do these bolt directly to factory points or do I need to drill new holes?

They mount at factory rocker and bed-side attachment points—no drilling. Verify hole alignment during test-fit before final torque.

What prep is needed before installation?

Clean the mounting surfaces with degreaser and let dry completely. The textured finish is ready to bolt on as-is; no priming or painting required unless you choose to match a custom color.

Are fasteners included or do I source my own?

Hardware is not included. Use grade 8.8 bolts and locknuts that fit your factory mounting holes—refer to your service manual for torque specs and bolt sizing to match your truck's original spec.
