How do I send my wheels in?
Tell us the grit you want back
Same grit or a different one, your choice, no extra cost. Write it on a note in the box or put it in the order.
Order online first
Add the sizes and grits you are sending to your cart and check out. That is how we match your box to your order when it arrives.
Wheels only
No boxes, no bushings, no arbors. They add weight to your shipping cost and we do not need them.
Pack them so they cannot move
A wheel loose in a box arrives with a damaged edge. Wrap each one.

Resurface vs buy new
| Size | Resurface (your worn wheel) | New SuperNova (ours) | New Nova (Diamond Pacific) | Save vs new SuperNova | Save vs new Nova |
|---|---|---|---|---|---|
| 4" | $34.95 | $69.95 | $123.33 | $35 (50%) | $88 (72%) |
| 6" | $39.95 | $79.95 | $144.00 | $40 (50%) | $104 (72%) |

2.5": $29.95. No new 2.5" wheel is sold, so there is no comparison.

How long does resurfacing take?
About a week from the day your wheels reach us.
Which wheels can you resurface?
We resurface
- Soft resin-bond wheels, any manufacturer
- Nova, SuperNova and unbranded wheels alike
- 2.5", 4", 6" and 8" diameters
- Wheels worn smooth with the core intact
We cannot
- Hard wheels: sintered, nickel bond and electroplated, including Galaxy

Not sure what you have? Call 714-771-7007 before you ship and we will tell you.
Can I change the grit?
Yes. Tell us the grit you want back and we will resurface it to that grit, at no extra cost. Same wheel, different grit.
What if I am not happy with it?
Mailing a wheel across the country to a company you have not used before is a leap. So the risk is ours. If you are not happy with a wheel we resurfaced, send it back for a full refund including your shipping.
