ACL Bearings 6B1238P-30 Performance Connecting Rod Bearing Set

The ACL Bearings 6B1238P-30 is a precision-engineered connecting rod bearing set designed for high-performance and racing applications. Manufactured by ACL Race Series, these bearings combine advanced metallurgy with race-proven design to deliver superior durability under extreme operating conditions.

Key Features:

• Tri-metal construction with high-strength overlay plate for improved fatigue resistance
• Hardened steel backing on all rod bearings to enhance support and bearing retention
• Reduced overlay thickness optimizes fatigue properties and load capacity
• Increased eccentricity compensates for bore distortion at high RPM and promotes hydrodynamic oil film formation
• Elimination of flash plating on bearing backs improves heat transfer and maximizes grip in housing
• Tight, consistent wall tolerances help maintain precise bearing clearances
• Enlarged inner diameter chamfers accommodate large fillet radius performance crankshafts

ACL Race Series bearings are trusted by engine builders worldwide and have proven themselves in competitive motorsports environments from drag racing to road racing. These bearings deliver the reliability and performance demanded by high-output engines operating under severe loads and sustained high RPM conditions.
