ACL Race Series bearings are designed for performance engine builds where durability and consistent oil clearances are important. When doing rods and pistons, replacing the bearings helps reduce fatigue, failure risk and drivetrain stress.

Race series bearing features include high-strength overlay plating, hardened steel backs, increased crush, improved heat transfer, increased eccentricity for high-rpm oil film formation, and tight consistent wall tolerances.

• Designed to withstand higher RPM conditions
• High strength overlay plate
• Hardened steel backs
