Enginetech BC118J25 Main Bearing Set Chrysler Cummins 5.9L 6.7L 0.25mm Oversized

The Enginetech BC118J25 is a crankshaft main bearing set designed for Chrysler and Dodge vehicles equipped with the Cummins 5.9L (359 CID) and 6.7L (408 CID) inline-6 diesel engines, including 12-valve and 24-valve configurations. This set is ground to 0.25mm oversized dimensions, making it the correct choice during engine rebuilds where the crankshaft journals have been reground to the first undersize.

The aluminum-silicon formulation provides excellent conformability, embedability, and fatigue resistance under the high loads characteristic of diesel engine applications.
