All used parts include a 6-month warranty from the date of purchase.
- If your part fails within 6 months, we will send a replacement
- Refunds are only issued if we cannot provide a suitable replacement
- Warranty covers defects — not installation errors, misuse, or damage after installation
Note: Warranty is for replacement, not refund. A part failing on day 80? We'll replace it. But the return window for refunds is 30 days.
Damaged in Shipping?
If your part arrives damaged:
- Stop immediately — do not install the part
- Keep all original packaging and boxes
- Take clear photos of the damage and packaging
- Contact us within 48 hours of delivery
We will handle the carrier claim. You are not responsible for shipping damage — we just need your help documenting it.
Order Cancellation
Orders can be cancelled before shipment for a full refund. Once shipped, cancellations follow our return policy.
