Race Rod Bearing Set, 52mm Journal

The ACL Race Rod Bearing Set is engineered for demanding high-performance applications, specifically for Subaru EJ20, EJ22, and EJ25 engines with a 52mm journal size. Key features include a high-strength overlay plate with reduced thickness for enhanced fatigue properties, and hardened steel backs to improve lining support and bearing retention. The design incorporates increased crush for better retention, and the elimination of flash plating on the back enhances heat transfer and ensures maximum grip between the bearing and its housing. To maintain consistent clearances, tight wall tolerances are maintained throughout the manufacturing process. Additionally, enlarged ID chamfers on the bearing edges accommodate large fillet radius on performance crankshafts. Installation of these bearings does not require machining, making them a straightforward replacement part for engine rebuilds. ACL bearings are a top choice for engine builders focused on high-horsepower builds, offering a blend of design, metallurgy, and engineering for reliable performance.
