ACL Race Series bearings are triple-layered metal in order to withstand the high-RPM conditions, high stress loads, and high temperatures experienced in race motors.
Race Series bearings features:
• larger chamfer to fit crank journal radii • 75% grooved to optimize bearing load carrying capacity and oil flow to rod bearings • increased crush and tighter wall tolerance for better seating • improved overlay and reduced thickness for increased fatigue strength • hardened steel backing to maintain crush under high loads and temperatures
