Do these fenders require fastening hardware?

Hardware is not included in this set. You'll need to source fasteners suitable for FRP-to-body mounting. Consult your wide body kit documentation for recommended fastener specifications and mounting point locations.

What prep work is needed before painting?

Sand the surface with appropriate abrasive to ensure paint adhesion, then clean thoroughly to remove dust and debris. Apply your chosen primer and topcoat following the paint manufacturer's instructions. Proper surface prep directly impacts finish durability.

Will these fit if I'm not running the complete wide body kit?

These flares are engineered as part of a complete wide body system. Using them standalone may result in panel gaps or fitment issues. Install them alongside the matching wide body kit for proper alignment and visual integration.
