What prep work do I need to do before painting?

Sand the primed surface with 220–320 grit to scuff the finish, then wipe clean with a tack cloth. This ensures your paint or clear coat bonds properly. Follow your paint manufacturer's surface prep guidelines for best results.

Does this include mounting hardware or fasteners?

The diffuser arrives as the raw panel only. You'll need to verify existing mounting points on your vehicle and source fasteners based on your attachment method — whether bolting to the bumper assembly or using adhesive tabs. Reference your vehicle's rear bumper structure before finalizing your install plan.

Will this fit if I've modified my rear bumper?

This piece is engineered for factory rear bumper geometry. If you've already installed aftermarket bumpers, splitters, or diffusers, check clearance and mounting hole alignment with your existing setup before ordering. A test fit or digital mockup saves install time.
