Do I need fasteners to mount these over fenders?

Mounting hardware is not included with the panels. You'll need to source fasteners appropriate for your vehicle's body mounting system and verify fitment against your original fender attachment points before drilling or bolting.

Should I sand these before painting?

Yes. Sand and prep the surface with appropriate grit before applying basecoat and clear coat. Clean away all dust between steps to ensure proper paint adhesion.

Will these fenders clear my current wheels and suspension setup?

Over-fenders extend the body line outward. Verify tire and suspension clearance against your specific wheel size and offset before installation. Measure the installed height on your vehicle to confirm fitment with your current setup.
