Bearings - There are asbolutely no returns on bearings that have been opened. Bearing clearances are a tricky part of engine building and sometimes the bearings you purchase will not yield your desired clearances. We have offered to exchange bearings in the past with a good amount of them showing back up damaged. For that reason, we will not longer offer any return, refund or exchange on any bearings. 

Pistons - Absolutely no returns or exchanged on custom pistons or pistons with options added on such as Gas Ports or Coatings. Please check the bore of your block or have your machinist check the bore before ordering pistons so you can make sure you are getting the correct size. Also, do not have the final hone done until the pistons are in your hands. All pistons come undersized for proper piston to wall clearance but that can vary a few thousanths. We have had way too many people trying to return pistons recently for the simple fact that they ordered the incorrect size. For this reason, there will be a firm 20% restocking fee.

Cylinder Heads - All Cylinder Head Packages are made to order with the options you choose. There will be no returns on any Cylinder Head Packages.

Rotating Assemblies - There will be no returns on Rotating Assemblies that have been balanced. If there is an issue with something we will be glad to work with you to resolve the issues as quickly and efficiently as possible.
