ACL is an engine builder’s top choice for its quality and consistency. Buy with confidence; you will find ACL in many cars on the road as they are an Original Equipment supplier. Many racers, especially import racers, swear by both their stock and performance series crankshaft rod and main bearings. ACL premium bearings will not only hold up better and longer than OEM, but the special coating process will also help prevent premature engine bearing failures and expensive engine damage.

ACL Race Series performance bearings are for extreme endurance under harsh conditions. Plan on running high RPMs and big boost? Fatigue, stress wear, and failure are factors you won’t have to worry about when you are running ACL’s top-of-the-line metallurgy.

Please Note When Ordering Bearings:Engine bearings require proper tolerance to be measured before purchase. If you are not sure what size bearings your build requires, please consult a professional engine builder. We are not responsible for incorrectly ordered bearings and can not take returns or provide exchanges on any engine internal components.

ALC’s main bearings are made of a softer metal so that you don’t wear out your crank or engine block. Additionally, a thin layer of oil lubricates the connection between the bearings and the crank allowing the crank to “float” and reduce wear. Proper support via main bearings is crucial to prevent oscillations and wear that can damage the crankshaft and other components as the motor moves further out of balance.Bearings with extra oil clearance will absorb the stress of higher horsepower motors greater, but will see increased wear during start up. We recommend these be purchased by experienced professionals only.
