ACL Bearings 4B1216P-STD Performance Connecting Rod Bearing Set Standard Size

The ACL Bearings 4B1216P-STD is a high-performance connecting rod bearing set engineered for demanding applications. ACL Race Series Engine Bearings feature high strength overlay plate with reduced thickness for improved fatigue properties, making them ideal for engines operating under increased stress and higher RPM conditions.

Key Features:

• 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
• Standard (STD) size for stock crankshaft journals
• Tri-metal construction for superior durability

Quality bearings can directly determine the longevity of your engine, and ACL's Race Series bearings are designed for engines that exceed factory specifications. Whether you're building a performance street engine or a full competition motor, these bearings provide the reliability and precision fit required for demanding applications.
