Do these over fenders require special installation hardware?

Over fenders typically bolt to existing body mounting points or bolt to the door jamb area. Verify your vehicle's OEM fastener locations before ordering hardware separately — many builders use stainless steel bolts and backing plates for corrosion resistance in high-vibration areas.

Should I sand and prime these before painting?

Sand the surface with appropriate grit to remove gloss and prep for adhesion, then apply your chosen primer and finish. FRP responds well to standard automotive paints once the surface is properly prepared — no special primers required.

Will these fenders affect tire clearance or suspension travel?

Over fenders extend the body outward. Measure your wheel and tire width, then verify fitment against the fender profile before installation — wider wheels may require test fitment or fender rolling depending on your suspension setup and ride height.
