Do these fenders require installation hardware, or is that included separately?

This kit includes the four FRP panels only. You'll need to source fasteners and mounting hardware separately based on your wide body kit's mounting points and your chosen installation method. Refer to your complete wide body kit's instructions for hardware specifications.

What prep work is needed before painting?

Sand the surface with appropriate sandpaper and clean thoroughly to remove dust and debris. Apply your chosen primer and paint system according to the manufacturer's instructions. Proper surface prep ensures even color match and long-term finish durability.

Are these designed to work standalone, or must they be part of a full wide body kit?

These over fenders are engineered to function as part of a complete wide body system. They're designed for gap consistency and panel alignment with the full kit, so they should be installed alongside all other wide body components for proper fitment.
