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

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

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
