Couldn't load pickup availability
Fiberglass rear diffuser engineered to add visual aggression and aerodynamic presence to your setup. Requires Surface Prep, ready for your choice of finish. Single-piece construction keeps installation straightforward and maintains clean panel lines.
Will this scrape on driveway approaches or steep inclines?
The SP-N diffuser extends beyond the stock bumper line. Test clearance on your typical approach angles and driveway grade before final installation. Adjusting your suspension ride height or avoiding extreme inclines will prevent contact.
Does this diffuser have functional downforce or is it cosmetic?
The SP-N design is primarily aesthetic. It enhances rear-end visual balance and complements aero-forward builds, but does not produce measurable downforce on its own. Pair it with other aero elements if you're targeting performance gains.
What prep and finish should I apply before installing?
Sand the surface with appropriate grit to scuff the primer, then apply your chosen paint or clear coat. FRP absorbs UV over time, so a quality topcoat protects against fading and keeps the finish fresh longer than bare primer.

It's designed for the fitment listed on this page. If your model has multiple bumper options (M Sport, GT, RS), confirm which one you have before ordering — these are specific to the bumper style.
Composite lips usually ship unpainted or in primer. The spec sheet on this page tells you what to expect.
Yes — most lips and diffusers are bolt-on or 3M tape-on, 30-90 minutes with basic tools. Some require drilling, which is permanent, so check the spec sheet for the mounting method before you start.
Most lips and splitters ship standard parcel (UPS/FedEx). Larger one-piece splitters may ship freight. Inspect your part before you sign for it and note any damage on the delivery receipt. Then email support@k2-industries.com with photos within 48 hours of delivery. Our team handles it with the carrier and the supplier, so you don't have to.

Yes. Duraflex parts are engineered for professional prep, prime, and paint. They're built for builders doing a proper custom finish. Your body shop has almost certainly worked with Duraflex before, it's the most widely used fiberglass aero brand in the aftermarket.
Your shop will sand, test-fit, smooth any minor imperfections, prime, and paint to your exact color spec. Minor waves or uneven edges on raw fiberglass are completely normal and are addressed during prep, this is standard for any custom aero build.
Duraflex parts are designed to fit within acceptable custom aero tolerances. Because they're flexible fiberglass rather than OEM plastic, minor adjustments during fitting are normal and expected. Your body shop will dial in the gaps during the test-fit stage before paint.
Inspect your part before you sign for it and note any damage on the delivery receipt. Then email support@k2-industries.com with photos within 48 hours of delivery. Our team handles it with the carrier and the supplier, so you don't have to.
