ACL Bearings 4B1930-STD Connecting Rod Bearing Set Standard Size

The ACL Bearings 4B1930-STD is a high-performance connecting rod bearing set engineered with tri-metal construction for superior durability and load capacity. This standard size bearing set is designed for Honda 4-cylinder 1342cc engines from 1987 applications, delivering the reliability and performance demanded by both street and racing applications.

Key Features:

• Tri-metal copper-lead construction with hardened steel backing for maximum strength and heat dissipation
• High strength overlay plate with reduced thickness for improved fatigue resistance
• Hardened steel backs improve bearing lining support and retention in the housing
• Elimination of flash plating on bearing backs maximizes heat transfer and housing grip
• Increased eccentricity compensates for bore distortion at high RPM conditions
• Tight consistent wall tolerances maintain precise clearances
• Standard (STD) size for OEM crankshaft journal dimensions

ACL Race Series bearings feature advanced metallurgy and engineering designed to withstand higher RPM conditions where standard bearings fail. The copper-lead tri-metal design provides excellent load carrying capacity and seizure resistance, making these bearings ideal for performance builds, forced induction applications, and racing engines that demand superior bearing performance.
