Do these require drilling into my factory fenders?

No. Over-fenders bolt directly to existing body mounting points, eliminating the need to drill into or modify OEM panels. Verify your vehicle's mounting hole locations before assembly.

What prep and paint should I use before installation?

Sand and prep the surface with appropriate grit to achieve your desired finish profile. Use your chosen primer, primer-filler, or paint system. Installation can happen before or after color coat depending on your preference — just ensure the panels are fully cured before mounting.

Will these fit with my existing wheel and suspension setup?

Over-fenders are designed to clear stock ride heights. If you run lowered suspension or larger-diameter wheels, verify clearance by test-fitting or measuring wheel diameter against the inner fender lip before final assembly.
