ACL is an engine builders top choice for their quality and consistency. Buy with confidence; you will find ACL in many cars on 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.

ACL Duraglide series bearings are a tri-metal design that provide a combination of high strength and the ability to withstand harsh / demanding operating conditions above casual driving. This makes them ideal for performance engines and rebuilds.

They've survived the rigors of both my workouts and laundry day. Breathability: The material mix allows for excellent breathability. My feet stay dry and cool, reducing the chances of blisters or discomfort during long sessions. Pack Value: Getting six pairs in one go is fantastic.
