ACL Bearings 5M2964HC-STD Race Series Coated Main Bearing Set for Nissan SR20DE/SR20DET

The ACL Bearings 5M2964HC-STD is a high-performance coated main bearing set designed for Nissan SR20DE and SR20DET 2.0L engines. This Race Series bearing set combines ACL's proven trimetal bearing technology with Calico's CT-1 dry film lubricant coating for superior protection and performance in high-RPM racing applications.

Key Features:

• CT-1 coating provides reduced friction, abrasive wear protection, and intermittent dry lubrication during startup
• High-strength overlay plate with reduced thickness for improved fatigue resistance
• Micron-tolerance machining ensures consistent wall thickness and reliable crush fit
• 3/4 grooved design optimizes bearing load carrying surface and oil flow to connecting rod bearings
• Increased eccentricity compensates for bore distortion at high RPM and assists hydrodynamic oil film formation
• Elimination of flash plating on bearing backs improves heat transfer and maximizes housing grip
• Standard size (STD) for use with factory crankshaft journal dimensions

ACL Race Series bearings are manufactured to exacting tolerances and are trusted by engine builders in motorsports applications ranging from drift racing to professional drag racing. The HC suffix denotes this bearing set includes the premium Calico coating for added protection in extreme performance builds.
