Policies

Shipping & Handling

• Standard shipping: 3-7 business days via UPS Ground
• Parts are carefully packaged to prevent damage during transit

Returns (30 Days)

We accept returns within 30 days of delivery for this part.

• Defective parts: We will replace the part or issue a refund at our discretion
• Electronic parts: Must be returned with the sealed inspection bag unopened. The clear bag allows full visual inspection before opening. Once opened, electronic parts can only be exchanged for a replacement if defective — no refunds
• Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
• Return shipping: We cover return shipping as part of our 100% money-back guarantee
• Parts must be returned in original packaging and unmodified condition
• Poorly packaged returns that arrive damaged will not be credited

6-Month Warranty

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.
