MIA's Description

The ACL Race Series Engine Crankshaft Main Bearing Set is a set of performance bearings designed for specific Buick V6 engines. These bearings utilize ACL's Duraglide™ F780 tri-metal material system for enhanced durability and performance in reconditioned engines.

The F780 material system features a steel-backed, sintered copper-lead-tin lining for superior strength, complemented by a lead-tin-copper overlay for excellent anti-seizure properties. This combination provides engine builders with confidence in their components' ability to withstand demanding applications.
