Warranty on Used Auto Parts

Warranty & Return Policy

Warranty Overview

All orders are processed on the same day the customer is charged. Standard delivery is 7 to 10 business days for freight parts and 5 to 7 business days for non-freight parts.

Buying used auto parts carries some risk, so every part is inspected before it leaves our warehouse. Our parts rarely fail, but if one does, Fastrack Car Parts backs used OEM parts with an industry-leading warranty of up to 30 / 60 / 90 days on light-duty parts, counted from the delivery date.

We also offer Optional Service Agreements (OSA) for additional coverage.

If you no longer need a part: a 25% restocking fee and the one-way shipping fee apply. The rest is refunded.
If a part is defective: Fastrack Car Parts does not pay return shipping, and no labor costs are covered.

In the Event of Failure

The customer pays all costs of examination, diagnosis, testing, and repair if no failure has occurred or the failure is outside this warranty's scope.
