Why Buy Used OEM Parts?

Checked & Tested

We check and test every used part before we sell it. It may show some wear, but it works and is ready to install.

Original Equipment

This is the same part your vehicle came with from the factory. It fits and works just like the original — because it is one.

Works Like New

A few marks on the outside don't change what's inside. The part works the way it should.

Big Savings

Pay 50–80% less than buying new. Same factory part, much lower price.

Policies, in plain English.

Shipping & Handling

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

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.

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

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.
