Do these bolt straight to the truck or do I need welding?

These mount at factory rocker points — no drilling or welding needed. Standard hand tools and a socket set get the job done.

Will I need to prep or paint these before bolting on?

No prep required. They ship in black finish ready to install. Just clean the mounting area on your truck and bolt them on.

Are all the fasteners and brackets included?

Mounting hardware specifics aren't listed — contact support or do a test fit against your vehicle before ordering fasteners separately if needed.
