ACL Duraglide 780 Series Bearings are made from extremely high quality multi-layered materials. A steel backing to provide supporting strength for the lining with Copper-lead (Tri-Metal). These are leaded bronze alloys, and are strong and adaptable. They provide the bearing with good fatigue strength, as well as good anti-seizure properties.

For crankshaft bearings this lining is combined with a softer electroplated lead based overlay to give the bearing better conformability and improved anti-seizure tolerance. ACL Duraglide Engine Bearings are a must for your performance or stock engine.
