Do I need fasteners to install these, or are bolts included?

These mount via factory bedside bolt locations. Bring your own fasteners or reuse your existing hardware if compatible. Verify bolt size and length against your vehicle's original specifications before installation.

Can I paint these before bolting them on, or should I install first?

Sand and prep the FRP surface before painting, then install. This lets you finish-paint at your own pace without masking around the truck body. raw FRP condition means the surface is prepped and waiting for your color coat.

Will these work with my factory taillights, or do I have to swap them?

These fenders are sized for 2009-2014 F-150 taillights. If you're keeping original fixtures, verify your current taillight housing dimensions and cutout locations match before purchase. A mock-up with cardboard templates will confirm fit without commitments.
