Construction & Design:
ACL bearings are crafted using premium materials and advanced manufacturing processes to meet the rigorous demands of high-performance engines. The bearing shells feature a multi-layer design, including a steel backing for strength, a copper-lead intermediate layer for load carrying, and a durable overlay that resists scoring and wear. This combination ensures excellent conformability and embeddability, allowing the bearing to adapt to minor imperfections in the crankshaft while protecting it from debris.
The extra oil clearance design improves oil flow around the bearing surface, reducing friction and heat buildup during high RPM operation. This design consideration is critical for maintaining bearing integrity in performance applications where engine stresses are significantly higher than stock conditions.
Installation & Fitment:
This bearing set is a direct fit replacement for Chrysler 345 5.7L Hemi V8 engines from 2003 and later. Installation requires standard engine rebuild procedures, including proper cleaning of bearing surfaces and precise measurement of bearing clearances using plastigage or micrometers. The extra oil clearance design means installers should verify compatibility with their specific engine build and oiling system to ensure optimal performance.
Professional installation is recommended to guarantee correct bearing alignment and clearance, which are critical for engine reliability and longevity.
