If it's in stock and ready to roll, your order usually hits the road within 1–3 business days.
For made-to-order or specialty items (like carbon fiber parts or custom builds), the turnaround can take up to 8 weeks — perfection takes time.
Either way, we'll keep you updated so you know exactly when your parts are leaving the pit lane.
Absolutely! Once your order ships, you'll get an email with a tracking link so you can follow its journey from our shop to your doorstep.
If your order ships via freight, you'll get a separate email with a direct link to the carrier's tracking page — easy and stress-free.
Things happen on the road — even to boxes. If your order arrives damaged, snap a few clear photos of the box and product and send them our way right away.
If your shipment is lost, just email or call us — we'll help track it down and guide you through the next steps to make it right.
Simple — spread the horsepower! Follow us on Instagram, YouTube, and Facebook, and most importantly, drop us a review on Google or Yelp to let others know about your experience.
Your feedback helps us grow, create more content, and keep bringing performance-driven parts to the community. 🏁
