Does this bumper work standalone, or do I need the full wide body kit?

This bumper is designed to be used in conjunction with a complete wide body kit. The proportions and cutouts are engineered around the full kit configuration, so panel alignment and fitment depend on the kit being installed together.

Will the lower valance and bumper line up evenly with the wide body panels?

Yes — this bumper is engineered for the wide body platform. Proper fitment depends on the rest of the kit being installed to spec and all components being mounted at factory reference points. Reference the wide body kit documentation for panel sequencing.

What prep work is required before painting?

Sand the entire surface with appropriate abrasive media and clean thoroughly to remove dust and mold release. Fill any minor imperfections with suitable filler and sand smooth. Once prepped, apply your chosen primer and paint system per the paint manufacturer's instructions.
