Product Description
The MAHLE MS-2328H H-SERIES MAIN BEARING SET is a premium performance bearing solution designed for 1989-2018 Dodge Ram and Ram 5.9L/6.7L Cummins diesel engines. Built for high-load diesel applications, H-Series bearings are engineered to provide improved fatigue resistance, superior embeddability, and enhanced durability for towing, racing, street performance, and heavy-duty engine builds.
MAHLE/Clevite H-Series bearings are commonly used in high-performance diesel engines because they feature a hardened steel backing and performance-oriented bearing construction designed to withstand elevated cylinder pressure, higher RPM, and increased crankshaft loading. These standard-size main bearings are ideal for engine rebuilds, performance builds, and competition Cummins applications.
Compared to standard replacement bearings, the H-Series design offers tighter crush control and improved load-carrying capability for demanding diesel engine environments.
