One often overlooked part when building an engine is the bearings. Getting a quality set of bearings can directly determine the longevity of your engine.
ACL has various types of bearings. This is their RACE bearing which is meant for engines that will be reving higher than stock, and see more abuse than they were meant to from the factory. This is a performance bearing, not a factory oem-replacement bearing.
These are ".025", they are .025mm THICKER than stock. Use this when you need .001" less oil clearance.
Always consult with your machine shop before buying bearings to determine which size would be optimal for your proposed use.
