The ACL 5M8309HX-STD high-performance main bearing set is designed for Subaru EJ20, EJ22 and EJ25 engines requiring standard-size main bearings with thrust control in the number 5 position. Engineered for demanding street, performance and competition applications, these bearings provide dependable crankshaft support and improved durability under increased loads and operating temperatures.

ACL HX-Series bearings feature an enhanced performance design with extra oil clearance to help support improved lubrication in high-performance engine builds. The tri-metal construction and carefully engineered bearing geometry promote reliable load distribution, resistance to fatigue and consistent operation when paired with a properly prepared crankshaft and accurately measured housing bores.

These bearings are suitable for select Subaru Forester applications from 1998 through 2002, including vehicles equipped with EJ-series engines. Always verify the engine code, crankshaft journal measurements, thrust-bearing location and required clearance before installation. Professional engine measurement and assembly practices are recommended to confirm compatibility and achieve the intended performance.
