• Precision manufacturing tolerances for consistent fit and performance
• Designed specifically for Chrysler 345 5.7L Hemi V8 engines (2003+)
• Improved oil film retention to protect against metal-to-metal contact
• Compatible with high RPM and high load environments

Construction & Design:

ACL Race Series con rod bearings are constructed using a tri-metal layering process that combines a steel backing with a durable copper-lead alloy and a thin overlay of a soft metal such as babbitt. This combination provides a balance of strength, conformability, and embeddability to handle the stresses of high-performance engines. The oversized design accounts for crankshaft grinding or modifications, ensuring a perfect fit and optimal oil clearance.

Each bearing is precision-machined and finished to exacting standards, guaranteeing uniform thickness and surface smoothness. This meticulous engineering reduces friction and heat generation, which are critical factors in maintaining bearing integrity during intense engine operation.

Installation & Fitment:

This bearing set is designed for Chrysler 345 5.7L Hemi V8 engines from 2003 and later, specifically for applications requiring a .025" oversized bearing to match modified crankshaft journals. Installation should be performed by a qualified engine builder or mechanic familiar with high-performance engine assembly. Proper measurement and clearance checks are essential to ensure optimal bearing performance and engine reliability.

No additional modifications beyond crankshaft sizing are typically required, but always verify compatibility with your specific engine build and machining specifications before installation.
