ACL 4B8320H-.25 High Performance Rod Bearing Set

The ACL 4B8320H-.25 is a precision-engineered high-performance rod bearing set designed specifically for the Subaru EJ20, EJ22, and EJ25 engines. Crafted with a unique blend of metallurgy and design, these bearings are built to handle the demands of higher RPM conditions, making them a solid choice for both daily drivers and performance enthusiasts alike.
