ACL Race main bearings for Subaru EJ20 / EJ25 / EJ16 …

ACL Race main bearings are trimetal engine bearings designed for higher RPM conditions and demanding engine operation. Their construction uses a high-strength overlay plate with reduced thickness for improved fatigue properties.

Increased eccentricity helps compensate for bore distortion at high RPM and assists in forming hydrodynamic oil films. The set includes ACL Race Series main bearings.

• High-strength overlay plate with reduced thickness
• Increased crush for improved bearing retention
• Flash plating eliminated from the back to improve heat transfer and grip in the housing
• Increased eccentricity to compensate for bore distortion at high RPM
• 3/4-grooved main bearings to optimize load-carrying surface area and oil flow
• Tight, consistent wall tolerances to help maintain consistent clearances

Suitable for: Saab 9-2X I, Subaru Baja I (B12), Subaru Exiga I (YA5), Subaru Forester I (SF) / II (SG) / III (SH), Subaru Impreza I (GC/GF) / II (GD/GG) / III (GE/GV) / III (GH/GR), Subaru Legacy I (BC) / I (BF) / II (BD/BG) / III (BE/BH) / IV (BL/BP) / V (BM/BR), Subaru Outback II (ESTATE/BH) / III (BL/BP) / IV (BR).

Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.

Sizes

STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
