Do I need fasteners to install these, or are they included?

Fasteners are not included. You'll need to source bolts and hardware that match your vehicle's OEM fender attachment points. Verify your existing mounting hole locations before purchasing to ensure proper fitment.

Should I sand the primer before painting?

Yes. Sand and prep the surface with appropriate abrasive before applying your chosen primer or paint. This ensures proper adhesion and a clean finish. Use the prep method recommended by your paint supplier.

Will these panels fit over my factory fenders?

These are over fenders designed to mount above the OEM units. Check your vehicle's existing fender contour and mounting points to confirm fitment with your setup. If your factory fenders have been modified or replaced, verify hole alignment before final purchase.
