Do these mount using factory bolt holes?

Yes. They bolt directly to the factory attachment points on the frame—no drilling, no custom brackets. Standard hand tools cover the installation.

Will these fit over running boards or rocker moldings?

Test-fit before committing to fasteners. Running boards vary by truck configuration. If you have factory plastic rocker protection, you may need to remove it first for a clean mount.

Do these need paint or coating before install?

They ship ready to bolt on. If you prefer a different finish or paint match, handle that before installation—it's easier to paint bars on a bench than on the truck.
