Core Return Required

Your old, used cylinder head is what we refer to as a "core".

With every order, unless explicitly specified otherwise, we require the core(s) to be returned within 21 days, starting from the date of delivery. To make the process easy, we will provide all the core return materials necessary to ensure your experience is seamless.

Attached to the outside of the box, there will be a yellow plastic pouch titled "Return Documents", which will contain a prepaid return label for each package. If the return labels did not make it to you, please contact us so we may send copies to you via email.

You can reuse the same box and packaging material in which the rebuilt head(s) comes in since we use heavy duty, double wall boxes. We ask that you tape the box thoroughly before shipping the core.

Once you have the core(s) packaged, you will need to remove the old shipping label from each box and place the prepaid return label on the package. It is imperative you remove all old labels to ensure there isn't any confusion with FedEx.

Once you have your box(es) ready to ship, all you have to do is drop it off at your nearest FedEx location, its that simple!

Please note we recommend dropping off the packages at an actual FedEx store and not a 3rd party shipper. We also highly recommend obtaining a receipt for your records.

We do not charge upfront for cores (meaning there wouldn't be a refund upon receipt of your core(s) and there wouldn't be any additional charges as long as the complete core is returned. If you don't have core(s), or believe your core is not in acceptable return condition, feel free to contact us.
