Main Bearing Set Mopar 5.7L/6.1L Gen III Hemi

The Main Bearing Set Mopar 5.7L/6.1L Gen III Hemi from KING BEARINGS is designed for builders and enthusiasts who require reliability in both stock and modified street applications. This bearing set serves as a critical foundation that supports the crankshaft under load, making it essential for engine rebuilding and performance upgrades.

Manufactured with precision-engineered bearing material and geometry tailored to the Hemi's journal specifications, this set ensures proper fitment and clearance tolerances. The MB5840XPC STDX designation indicates that it is a standard-bore main bearing set, designed to maintain adequate oil flow while minimizing deflection during operation.

Builders restoring 5.7L Hemi engines or upgrading 6.1L stroker platforms will find this bearing set invaluable during long-block assembly and crank installation. Proper main bearing selection is crucial when upgrading fuel injection, cam profiles, or supercharger packages, as these modifications increase crankshaft stress and require reliable support.
