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

- 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
