Do I need fasteners to install these?

Installation hardware is not included. You'll need to source fasteners appropriate for your mounting points — verify your factory hole locations before ordering hardware so you get the right size and length.

What prep work is required before painting?

Sand the surface and apply your chosen finish system — primer, base coat, and clear are standard. Ensure the surface is clean and dry before applying any coating.

These are designed as over-fenders that bolt on top of your factory panels. Check your current tire and suspension setup against the bulge profile to confirm adequate clearance — oversized tires or lifted suspensions may require verification before installation.
