ACL Bearings 6B2390HC-.025 Race Series Rod Bearing Set 0.025" Oversize CT-1 Coated

The ACL 6B2390HC-.025 is a high-performance connecting rod bearing set designed for Nissan VG30DETT 3.0L and VG33E V6 engines, featuring a precision 0.025" oversize for machined crankshafts. These coated bearings combine ACL's tough Race Series lining and overlay metallurgy with Calico's well-renowned CT-1 coating, delivering the ultimate protection for extreme performance applications.

CT-1 Calico Coating Technology:

• CT-1 Dry Film Lubricant coating helps reduce friction and abrasive wear, provides intermittent dry lubrication and is not affected by dust or dirt
• CT-1 coated bearings have shown a reduction in oil temperatures as much as 15°F - 20°F
• Provides reliable dry film lubrication, protecting the engine from temporary oil shortages and foam formation, ensuring secure lubrication even during lubrication interruptions
• Professional engine builders enjoy increased embeddability, strength and durability with Calico coated engine bearings

Race Series Performance Features:

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve support of the bearing lining and assist with bearing retention
• Increased crush for improved bearing retention
• Elimination of flash plating on bearing backs to improve heat transfer and maximize grip between bearings and housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• Tri-metal construction combining copper-lead alloy with steel backing and electroplated babbitt overlay

ACL Race Series performance bearings are engineered for extreme endurance under harsh conditions, making them ideal for high-RPM, high-boost turbocharged applications. ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world, with Race Series rod and main bearings serving as standard components in race engines that have set records and won championships.
