1989-2017 Cummins 5.9L/6.7L Mahle Main Bearing Set - Standard (MS-2328P)

1989-2017 Cummins 5.9L/6.7L Mahle Main Bearing Set (MS-2328P)

The Mahle MS-2328P P-Series Main Bearing Set (Standard) provides you with top quality engine bearings for your 1989-2017 Dodge Ram 5.9L/6.7L Diesel. The Mahle P-Series are the oldest series of Mahle high performance bearings. Most P-Series main sets are full grooved to maximize oil flow to the bearings. The P-Series has a high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue, sometimes referred to as hen tracking.

Use P series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings. Rod bearing oil starvation is typically indicated by polishing and smearing of the bearing surface, possibly accompanied by discoloration predominantly concentrated at the axial center of the bearings.
