ACL Bearings 5M7299H-001 Race Series Main Bearing Set

The ACL Bearings 5M7299H-001 is a high-performance main bearing set designed for Chevrolet V8 LS Gen III/IV engines. This Race Series bearing set features .001 inch crankshaft undersize dimensions, making it ideal for precision engine builds and racing applications.

Key Features:

• Multi-layered tri-metal copper alloy construction for high strength and excellent seizure resistance
• 120-degree groove design for improved oil flow and distribution
• Manufactured to exact tolerances ensuring reliable fit and consistent clearances
• Increased crush to lock bearings securely into housing for better heat dissipation
• Enhanced bearing eccentricity for improved shape adaptation under high-speed operation
• Enlarged I.D. chamfers and extended grooves for optimal lubrication

ACL Race Series bearings are precision-engineered with micron-tolerance machining to deliver the performance and durability demanded by racing applications. The tri-metal construction combines a high-tensile steel backing, copper-lead-tin lining for fatigue strength, nickel barrier layer, and lead-tin-copper overlay for superior abrasion resistance and low friction operation.
