Return Policy

From delivery, not from your purchase or order date. The clock starts the day the freight carrier delivers your crate, as recorded by the carrier's tracking event. You have 30 full calendar days from that delivery date to request a return. Orders that have not yet been delivered can be cancelled at no charge at any time before the crate ships.

Email with your order number, the reason for the return, and photos if the part arrived damaged or incorrect. You can also call (Mon-Sat, 8:00 AM - 6:00 PM CT). We reply within 1 business day and issue a Return Merchandise Authorization (RMA) number along with the return shipping address and instructions. Do not ship a part back without an RMA number; freight arriving without one may be refused at our dock.

The engine or gearbox must not have been installed, started, or run, and must not have been filled with oil, coolant, or transmission fluid beyond the factory test fill it shipped with. It must be complete with every accessory it shipped with (torque converter, sensors, brackets, dyno certificate, manuals) and returned in its original crate or an equivalent crate providing the same protection. Units that have been installed, started, or are missing parts are not eligible for a standard return; see Section 9 and 10 below for damaged or wrong-item exceptions, which are not affected by this requirement.

If you are returning a part because you changed your mind, ordered the wrong application, or no longer need it, you pay the return freight, and the original outbound freight charge is not refunded. If the return is because we shipped the wrong item, the part arrived damaged or defective, or the part does not match its listed specifications, we pay return freight in full and refund 100% of what you paid, including the original freight charge.

Original outbound freight is refunded only when the return is our error (wrong item shipped) or a covered defect. If you are returning a correctly shipped, undamaged part for a reason of your own (fitment mistake, change of mind), the original freight charge is non-refundable and you are responsible for return freight.

Customer-initiated returns of undamaged, correctly shipped parts carry a 12% restocking fee, deducted from your refund, to cover inspection, re-testing on our dyno, and relisting. There is no restocking fee, and no charge to you at all, when the return is due to our error or a covered defect.

We inspect every returned unit as soon as it arrives at our facility, which typically takes 2-4 business days depending on freight transit time. Once inspection confirms the item meets the condition requirements above, we issue your refund within 5 business days. Refunds are issued to the original payment method used at checkout; if that method is no longer available, we issue a bank transfer or check to the name on the order instead. Bank posting times after we issue the refund typically add 2-7 business days, depending on your bank.

Do not refuse the shipment. Accept the delivery, note any visible damage on the carrier's delivery receipt before the driver leaves, and photograph the crate and the damage. Email us at within 48 hours of delivery with your order number and photos. We handle the freight damage claim directly with the carrier at no cost or effort to you, and we will repair, replace, or fully refund the unit, including all shipping charges, at your choice.

Email with your order number and a photo of the part's tag or label within 7 days of delivery. We will send a prepaid return freight label immediately and ship the correct part as soon as you confirm the incorrect unit is ready for pickup (we do not require you to wait for the wrong part to arrive back before we ship the replacement, in most cases). You pay nothing extra: no restocking fee, no return freight cost, and no charge for the replacement shipment.

If your order included a core credit, return your complete, rebuildable core within 60 days of delivery using the prepaid freight label included with your crate. Cores must be drained of fluids. We inspect cores within 10 business days of arrival and issue the agreed core credit to your original payment method. Core returns are separate from, and do not affect, the standard 30-day return window above.

A return is for a part you want to send back within 30 days of delivery. A warranty claim is for a part that fails after installation, and is covered separately by the 5-year/100,000-mile (engines) or 4-year/80,000-mile (gearboxes) limited warranty described in our Terms of Service. To start a warranty claim, contact us with your order number and a description of the issue; our technicians triage within 2 business days and may request photos, an oil analysis, or inspection by a certified shop.
