Main Bearing Set - Mopar 6.4L Gen III Hemi

The Main Bearing Set for the Mopar 6.4L Gen III Hemi is engineered for operators and enthusiasts who demand reliability in extreme-duty applications where engine integrity is non-negotiable. Built by MAHLE ORIGINAL/CLEVITE, this bearing set restores critical load-carrying capacity at the crankshaft, where peak combustion pressures concentrate during high-performance operation. Whether you're rebuilding after catastrophic failure or upgrading to handle increased boost or nitrous demands, this component is the foundation upon which engine longevity depends.

Main bearings function as precision load-bearing interfaces between the rotating crankshaft and the engine block, maintaining critical clearance tolerances while dissipating heat and distributing oil film under extreme pressures. The MS2296HX set utilizes OEM-spec materials and precise geometry to meet the exact journal diameters and thrust requirements of the Gen III Hemi platform, ensuring proper fit and oil flow characteristics. Each bearing is manufactured to eliminate run-out and concentricity issues that compromise durability, and the set accounts for the specific block architecture and crank profile of Mopar 6.4L engines, preventing premature wear and catastrophic bearing knock.

This bearing set is essential for complete engine rebuilds on 6.4L Gen III Hemi platforms used in high-performance trucks, muscle cars, and tactical mobility platforms requiring absolute dependability. Installation demands proper block preparation, accurate torque sequencing, and verification of crankshaft runout to ensure maximum service life. Use this set in conjunction with matching rod bearings, gasket sets, and fresh oil to restore factory performance or support modified engine combinations pushing beyond stock output levels.
