Do I need to sand and prep these before painting?

Yes. Sand the surface with appropriate grit to create tooth for your base coat, then wipe clean before applying your chosen finish. This ensures paint adhesion and a professional result.

What fasteners and hardware do I need to install these?

Over fenders typically mount using factory attachment points on your OEM fenders. Verify your vehicle's existing fastener locations and hole patterns before installation. You may need additional fasteners depending on your setup—check your vehicle's service manual or compare with OEM hardware.

Will these interfere with my current wheel and tire setup?

The bulge profile adds visual width but does not increase the actual wheel well opening. Confirm your current tire diameter and offset against the fender profile by test-fitting or consulting your vehicle's clearance specifications to ensure no rubbing at full lock or suspension travel.
