ACL Nissan VG30DETT 3.0L-V6 Standard Size High Performance Rod Bearing Set - CT-1 Coated

The ACL 6B2390HC-STD is a standard size high-performance rod bearing set designed for endurance in motorsports. These bearings utilize a unique combination of design, metallurgy, and engineering to provide superior durability and capability for demanding engine applications.

Constructed with tri-metal hardened steel backs, these bearings enhance support for the lining and aid in retention within the housing. They feature increased crush for improved bearing retention and elimination of flash plating on the back to improve heat transfer and grip. The design includes increased eccentricity to compensate for bore distortion at high RPM and assist in forming hydrodynamic oil films. Additionally, the 3/4 grooved main bearings optimize load-carrying surface area and oil flow, while tight, consistent wall tolerances ensure precise clearances.
