The ACL Race Series Rod Bearings are engineered to support high-RPM, high-stress engine environments. Featuring a tri-metal construction and hardened steel backing, these standard-size bearings provide excellent oil film control, increased fatigue resistance, and reliable bearing retention for demanding street or motorsport builds.

Key Features

• Trimetal construction with high-strength overlay for enhanced fatigue properties

• Standard size with additional undersizes available (.025, .25, .50)

• Hardened steel backing for improved support and housing retention

• Increased crush and eccentricity to adapt to high-RPM bore distortion

• Elimination of flash plating to enhance heat dissipation and housing grip

• Precision-machined for consistent wall tolerances and oil clearance

• Enlarged chamfer to accommodate large fillet radius crankshafts

• Designed with one oil hole and notch

• Direct fit; no machining required
