ACL Race Series Standard Size Rod Bearings are engineered for high-performance Subaru EJ engines. Designed to handle increased loads, RPM, and heat, these trimetal bearings offer exceptional fatigue resistance and consistent oil film for improved durability under extreme conditions.

Key Features

• Trimetal race-grade construction for enhanced strength and load capacity

• High-strength overlay with reduced thickness for improved fatigue properties

• Hardened steel backing improves structural integrity and bearing retention

• Increased crush and eccentricity to compensate for high RPM bore distortion

• Flash plating eliminated on the backing for superior heat dissipation

• Precision wall tolerances for consistent bearing clearances

• Suitable for both naturally aspirated and turbocharged EJ engines

• Drop-in fit – no machining required

Vehicle Fitment
Compatible with a wide range of Subaru and Saab models equipped with EJ-series engines and 52 mm crank rod journals, including:

• Subaru Impreza (WRX, WRX STI, RS, Outback Sport) – various models 1990s–2021

• Subaru Legacy & Legacy GT – multiple EJ engines

• Subaru Forester, Exiga, Baja – EJ20, EJ22, EJ25 variants

• Subaru Outback (non-H6 variants) – EJ253, EJ251, EJ255

• Saab 9-2X – EJ253 and EJ255 engines

Includes compatibility with EJ151, EJ161, EJ18E, EJ20E, EJ20G, EJ20K, EJ20T, EJ205, EJ207, EJ208, EJ22E, EJ22G, EJ22T, EJ253, EJ255, EJ257, EJ25D engines.

Important: Confirm journal size before purchase. This bearing set only fits EJ engines with 52 mm rod journals. Subaru EJ engines may also use 48 mm journals — measuring is required to ensure proper fitment.
