Description

The ACL 5M429H-10 is a set of race series main bearings designed for high-performance race engines. They are constructed with a nominal composition of 80% Copper, 10% Tin, and 10% Lead.

These bearings feature increased eccentricity to improve shape adaptation, which helps compensate for bore distortion during high-speed operation. They are suitable for applications from sport compact to small block race machines and are trusted by champions worldwide.
