Do I need fasteners to mount these to my vehicle?

These panels use factory mounting points, but fasteners are not included in this set. Source stainless steel bolts and washers that match your OEM hole diameter and pitch — your vehicle's service manual specifies the correct fastener size. Verify hole alignment on your specific bumper frame before final tightening.

What prep work is required before painting?

Sand the primer surface with appropriate automotive sandpaper and clean thoroughly to remove all dust and debris. Apply any epoxy primer or filler as needed to achieve your desired finish quality. These panels are ready to accept paint once prepped — no additional surface treatment is required.

Can I install just one fender, or must I buy both?

Each panel is independent — install the left, right, or both. There is no functional dependency between sides, so you can stage your build or replace a single panel without committing to the full set.
