Do these mount to my existing fenders or replace them?

These bolt over your original fenders. You keep the factory panels in place — the new pieces extend outward to create the wider stance. Existing fender holes align with factory mounting points for a clean install.

What surface prep do I need before painting?

Sand the surface with medium-grit paper to ensure proper adhesive bond and smooth topcoat lay. Wipe clean and apply your chosen primer before color coat. This step ensures paint adhesion and a professional finish.

Will these affect my wheel fitment or tire clearance?

The extended fender width accommodates wider wheels and lower offsets. Before installation, verify your wheel and tire diameter against the new fender profile — test fit if possible to confirm clearance under full suspension compression.
