ACL 5M8309H-.25 Subaru EJ20, EJ22 and EJ25 High Performance Main Bearing

ACL Subaru EJ20/EJ22/EJ25 (For Thrust in #5 Position) 0.25mm Oversized High Performance Main Bearing

The ACL 5M8309H-.25 high performance main bearing is designed for Subaru EJ20, EJ22 and EJ25 engine applications requiring additional clearance correction in the thrust bearing location. This bearing is manufactured 0.25 mm oversized to accommodate a properly prepared engine block and crankshaft assembly. It is specifically intended for thrust in the number five position, making it important to verify engine configuration and machining specifications before installation.

Built for performance-oriented Subaru engine projects, this ACL main bearing supports reliable crankshaft positioning and consistent bearing operation under demanding conditions. Its high-performance construction is suitable for rebuilt, modified and competition-focused engines when installed with correct oil clearances, bearing orientation and assembly procedures. Always inspect the block, crankshaft journals and bearing saddles for wear or damage, and confirm the required oversize specification with measured components.

This application fits select Subaru Forester models equipped with compatible EJ-series engines, including 1998, 2000, 2001 and 2002 model years. Because engine configuration and thrust-bearing location can vary, confirm the vehicle, engine code and machining requirements before ordering. The ACL part number 5M8309H-.25 should be matched against the engine builder’s specifications to ensure correct fitment and performance.
