ACL Bearings 4B583P-STD Standard Size Connecting Rod Bearing Set

The ACL Bearings 4B583P-STD is a precision-engineered connecting rod bearing set designed to deliver reliable performance in demanding automotive applications. ACL Race Series bearings are recognized throughout the motorsports industry for their exceptional quality and durability, from sport compact drift racing to professional NASCAR, IHRA, and NHRA competitions.

Key Features:

• High-strength steel backing provides superior tensile strength for improved rod bearing retention and support
• Increased crush improves bearing retention through higher radial contact pressures and enhanced heat dissipation
• Increased eccentricity compensates for bore distortion at high RPM and assists in the formation of hydrodynamic oil films
• Elimination of flash plating on bearing backs maximizes heat transfer and grip between bearings and housing
• Tight, consistent wall tolerances help maintain precise bearing clearances
• Standard size (STD) specification for original equipment crankshaft journals

ACL's unique combination of advanced metallurgy, precision engineering, and race-proven design provides connecting rod bearings with the endurance and capability to perform where others cannot. Each bearing set is manufactured to exacting tolerances to ensure optimal performance and longevity in both street and racing applications.
