Overview

The ACL 6B2455HX-STD is a high-performance engine bearing designed for demanding applications. It features a standard size for a direct fit in stock configurations and includes extra oil clearance to help keep bearing surfaces lubricated. These bearings are built to handle high RPM conditions and ensure dependability.

Constructed with a high-strength overlay plate and hardened steel backs, these rod bearings offer improved support and retention. They also feature increased crush for better grip and elimination of flash plating to enhance heat transfer. The design includes increased eccentricity to compensate for bore distortion at high RPM and to aid in hydrodynamic oil film formation.
