Do these fenders require drilling or modification to the existing body?

No drilling required. Over-fenders bolt directly over your factory panels using existing or new fastener points. Verify your vehicle's OEM fender mounting locations before assembly to confirm hole alignment with your specific setup.

What prep work is needed before paint?

Sand and prep the surface thoroughly before applying your chosen topcoat. A clean, properly abraded surface ensures best paint adhesion and finish quality. Follow your paint manufacturer's surface preparation guidelines for optimal results.

Will these fit over a lifted or lowered suspension?

Over-fenders are designed to sit above the factory panel line. If your vehicle has significant suspension changes that alter fender-to-tire clearance, measure the final height and distance from the tire bulge to confirm adequate fitment before final installation.
