Do these fenders require drilling into the factory body?

No. These over fenders are engineered to integrate with factory mounting points. Before installation, confirm your vehicle's OEM fender hole locations and fastener pattern to ensure a clean fit.

What prep work is needed before painting?

Sand the surface with appropriate abrasive media to promote paint adhesion, then wipe clean. Apply your chosen primer and topcoat system according to the paint manufacturer's instructions. Proper surface prep ensures long-term durability and finish quality.

Will these affect tire clearance or suspension geometry?

These are over fenders designed to sit above the existing body line. Verify clearance between the fender and your tire size, wheel offset, and suspension setup before final installation. If running lowered suspension or aggressive wheel fitment, mock-fit and confirm adequate gap.
