Do these fenders require the complete wide body kit to install?

Yes. These over fenders are engineered as part of a full wide body conversion and must be used in conjunction with the complete kit. The mounting points and alignment are designed around the full assembly.

What prep work should I do before painting?

Sand the primer surface with appropriate grit to promote paint adhesion, clean off all dust and debris, and apply your chosen primer or base coat system. FRP requires proper surface preparation just like any panel before final topcoat.

What fasteners or hardware do I need to install these?

Verify the mounting points on your vehicle's OEM fenders and reference your wide body kit documentation for the correct fastener type and count. Installation hardware requirements vary by kit configuration.
