ACL Bearings 1B927H-01 Race Series Connecting Rod Bearings

ACL Bearings Race Series Connecting Rod Bearings deliver motorsport-proven performance for high-RPM, high-load engine builds. Engineered with advanced tri-metal construction and precision metallurgy, these connecting rod bearings are trusted in record-setting race engines across sport compact, NASCAR, IHRA, and NHRA competitions.

Key Features:

• High-strength overlay plate with reduced thickness for superior fatigue resistance
• Hardened steel backing improves bearing retention and support under extreme conditions
• Elimination of flash plating on bearing backs maximizes heat transfer and grip in housing
• Increased eccentricity compensates for bore distortion at high RPM
• Enlarged ID chamfers accommodate performance crankshafts with larger fillet radii
• Tight, consistent wall tolerances ensure reliable clearances and reduced wear
• Increased crush for improved bearing retention in housing

The -01 designation indicates this bearing set features 0.001" extra oil clearance on standard journal sizing, ideal for optimizing clearances in performance applications. ACL Race Series bearings combine innovative design with exacting tolerances to deliver unmatched endurance and capability where standard bearings fail.
