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.

Verify before ordering — please confirm your vehicle's year, make, model and sub-model specifications before placing your order. If anything is unclear, our customer service team is available to help.
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.
