After you have made your purchase, please follow the steps listed below to receive your refundable Core charge. This process must be completed within 60 days of receiving your product(s). Failure to send us the core(s) within the 60 day timeframe will result in you only receiving a partial refund amount of the core deposit. 

1) On the outside of the ORIGINAL box, please write "Core Return" and your Original Invoice Number/Order Number.

2) Ship your core with tracking to:

Unit 6 - 1060 Stevens Road, West Kelowna BC Canada V1Z1A3 

3) Once we receive the Core here at the shop, it will be inspected to ensure that it is rebuildable. After the inspection is passed, your core charge will then be refunded (giving you more money for truck parts!).
