Do these over fenders come with mounting hardware?

The set includes the FRP panels only. You'll need to source fasteners and brackets appropriate for your mounting method. Check your vehicle's service manual or a dedicated installation guide for the correct fastener size and torque specifications.

What prep work do I need to do before installation?

Sand and prep the mounting surface on your factory fenders to ensure proper fitment and adhesion. The panels arrive in raw FRP condition, so you can paint them once mounted or before, depending on your preference and installation sequence.

Will these affect my wheel clearance or suspension geometry?

Over fenders add minimal extension to the wheel opening. Verify your wheel and tire dimensions against the new fender line before committing to fitment. If you've modified suspension or run wider wheels, test-fit or consult a performance shop to confirm no contact points occur.
