ACL Bearings 8B1633P-STD Performance Connecting Rod Bearing Set

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, designed for high-performance and racing applications. This connecting rod bearing set features advanced tri-metal construction engineered to withstand extreme conditions.

Performance Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing
• Increased crush for improved bearing retention
• Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing
• Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films

The STD designation indicates this bearing set is designed for standard-size crankshaft journals. The unique combination of design, metallurgy and engineering provides Race Series performance bearings with the endurance and capability to perform where others cannot, making them ideal for engine builds requiring superior durability and precision.
