Shipping policy
Processing time
In-stock items ship within 1–2 business days. Business days are Monday–Friday, excluding US holidays.
Backorders
Out-of-stock items ship within the lead time shown at checkout. Payment is collected in full when you order. We will email you if the lead time changes. You can cancel a backordered item any time before it ships for a full refund.
Delivery times
Delivery times below start once your order ships. They are estimates from the carrier, not guarantees.
| Service | Region | Estimated delivery |
|---|---|---|
| Ground | Western US | 1–2 business days |
| Ground | Central US | 2–4 business days |
| Ground | Eastern US | 4–6 business days |
| Ground | Canada | 7–14 business days |
| Next Day / 2 Day / 3 Day | US | 1 / 2 / 3 business days |
Choosing an expedited service shortens transit time only. It does not speed up processing or backorder lead times.
Shipping restrictions
We cannot ship air intake kits, charge pipes, oil catch can kits or turbo resonators to California addresses. Orders for these items to a California address will be cancelled and refunded in full.
Tracking, insurance and signature
Every order ships with tracking. Orders over $500 ship insured and require a signature on delivery. You can request a signature on any order by contacting us before it ships.
Please make sure your shipping address is complete and correct at checkout, including any unit or suite number.
Lost, stolen or delivered-but-not-received packages
If tracking shows your order as delivered but you cannot find it:
- Check around the delivery location, with neighbors, your building office or mailroom, and anyone at the address who may have accepted it.
- Allow one business day. Carriers sometimes mark packages delivered before they arrive.
- Contact us within 14 days of the carrier's delivery scan by phone, email or our web form.
We will open an investigation with the carrier the same business day. You do not need to file anything with the carrier yourself. Within 7 business days of your report, we will send a replacement. If the item is out of stock, or you prefer, we will issue a full refund instead.
We may ask you to confirm in writing that you did not receive the package. If the package turns up later, please let us know so we can arrange its return.
Packages returned to us
If the carrier cannot deliver your package after its delivery attempts and returns it to us, we will contact you. We can reship it once you pay the shipping again, or refund the merchandise. Original shipping charges are not refunded in that case.
Cancellations
There is no cancellation fee. Orders cancelled before they ship are refunded in full. To cancel, contact us by phone, email or web form as soon as possible. Once an order has shipped, it can no longer be cancelled and is handled as a return under our Refund Policy.
International orders
All orders ship from the United States. You are responsible for all import and export duties, taxes, tariffs and brokerage fees charged by your country. Shipping charges at checkout do not include them, and we cannot estimate them in advance.
If you refuse a shipment or do not pay these charges and the package is returned to us, we will either reship it after you pay the shipping again, or refund the merchandise less the original shipping, the carrier's return charges and a 20% restocking fee.
