What is a Refundable Core Deposit?
A “core” is what the industry calls your old defective part. We want cores to rebuild, recycle and/or resell.

Many of our parts have refundable core deposits. This means you pay a temporary deposit at the time you buy a part. Then, we fully refund the deposit once you send us your old part.

Here's how it works:

  • You purchase the part you need to fix your vehicle.
  • You pay a temporary refundable core deposit. Don’t worry, you’ll get this back!.
  • You ship us your old part (the core).
  • When we receive your old part (the core), we refund you the full amount.

If you have any questions about core deposits, please feel free to give us a call at (888)-907-7225 and we will be happy to assist you.

How long do I have to send back my core?
-Cores must be returned within 90 days from purchase to ensure full credit.
