ACL Bearings 3B1012-STD Connecting Rod Bearing Set Standard Size

ACL Race Series Connecting Rod Bearings bring race-tested durability, precision engineering, and state-of-the-art metallurgy into your high-performance build. Their trimetal design features a high-strength overlay plate with reduced thickness for improved fatigue resistance, backed by hardened steel for enhanced support and retention under extreme conditions.

Key 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
• 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
• Tight consistent wall tolerances to help you maintain consistent clearances

ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world. These bearings deliver when the going gets tough—on the street, the strip, or the racetrack. The STD designation indicates standard journal size for stock or standard-ground crankshafts.
