ACL Bearings 4B610PO/S2-30 Performance Connecting Rod Bearing Set

The ACL Bearings 4B610PO/S2-30 is a high-performance connecting rod bearing set engineered for demanding applications where reliability and precision are critical. This trimetal bearing features advanced metallurgy and design characteristics that deliver superior performance compared to standard replacement bearings.

Key Features:

• High-strength overlay plate with reduced thickness for improved fatigue resistance
• Hardened steel backing on all rod bearings to enhance lining support and bearing retention
• Elimination of flash plating on bearing backs to maximize heat transfer and improve grip in housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist hydrodynamic oil film formation
• Tight, consistent wall tolerances to help maintain precise bearing clearances
• Enlarged inner diameter chamfers on bearing edges to accommodate large fillet radius performance crankshafts

ACL Race Series bearings combine proven design, advanced metallurgy, and precision engineering to deliver the endurance and performance required in high-output engines. These bearings are trusted in motorsports applications ranging from drift racing to professional drag racing competitions.
