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

Fasteners are not included in this set. You'll use the existing factory bolt holes to secure the over fenders to your vehicle. Verify your mounting point hardware is in good condition before installation.

What prep work is needed before painting?

Sand the surface with appropriate grit to scuff the finish, then clean thoroughly to remove dust. This ensures proper paint adhesion. Follow your chosen paint manufacturer's recommendations for primer and topcoat application.

Will these interfere with my suspension or wheel setup?

These over fenders are designed to clear factory suspension geometry. For significantly lowered vehicles or wheels with aggressive offsets, dry-fit and verify clearance before final installation—roll the wheel lock-to-lock to confirm no contact.
