Do these mount at the factory holes or do I need to drill?

Mount at factory anchor points — no drilling. Use the existing fastener locations on your fenders.

Can I paint these right out of the box or do they need prep?

Primer-ready means they've been prepped for paint. Light scuff with 400-grit, wipe down, and prime before color coat. No stripping or heavy sanding needed.

What hardware comes with these flares?

The flares ship without fasteners — you'll use your existing factory bolts at each mounting point. Confirm bolt condition before install.
