ACL Bearings 5M2964HXC-STD Race Main Bearings Coated Extra Clearance Nissan SR20

The ACL Bearings 5M2964HXC-STD is a high-performance coated main bearing set engineered for Nissan SR20 engines including SR20DE, SR20DET, SR18DE, and SR20VE applications. This standard size bearing set features ACL's advanced CT-1 dry film lubricant coating combined with extra oil clearance (HXC designation) for enhanced performance in high-RPM racing applications.

Advanced CT-1 Coating Technology:

• CT-1 dry film lubricant coating reduces friction and abrasive wear during operation
• Provides intermittent dry lubrication protection during startup and extreme conditions
• Coating is unaffected by dust or dirt contamination
• Specifically engineered to withstand extreme conditions in high-performance engines

Race Series Performance Features:

• Extra oil clearance (HXC) design optimized for high-RPM racing applications
• High-strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backing for superior lining support and bearing retention
• Manufactured to micron-level tolerances for consistent wall thickness and crush
• Increased eccentricity compensates for bore distortion at high RPM
• Improved heat transfer through elimination of flash plating on bearing backs
• 3/4 grooved design optimizes load-carrying surface area and oil flow

ACL Race Series bearings combine decades of motorsports experience with advanced metallurgy and precision manufacturing. These bearings are proven in championship-winning race engines from drift racing to NASCAR, IHRA, and NHRA competitions.
