Warranty

All pieces carry a one-year manufacturing warranty from date of purchase. This covers defects in materials, workmanship, and construction faults. This does not extend to normal wear and tear, or improper care. This warranty applies only to purchases made directly through our site.

For any claim, reply to your order confirmation email or write to info@rule28.cc with your order number and clear photos. We’ll handle it the same day.

Crash Replacement

If the worst happens and your kit is damaged beyond repair in a crash, send us clear photos of the damage along with your original order details.

We’ll sort a discounted replacement the same day we receive them. Like-for-like where possible.

This sits alongside the standard one-year manufacturing warranty and doesn’t cover normal wear or misuse.

Just email info@rule28.cc — we’ve got your back when the road doesn’t.
