1989-2018 5.9L & 6.7L Cummins Clevite 20 Undersize Main Bearing Set

Running a 6.7L Cummins and need to grind the crank undersize to clean it up? We don't recommend it, they like to break.
Try to find yourself a new crank shaft instead. 

20 under is equal to .50mm

Part# MS-2328P-.50mm or MS2328P-.50mm

Lame California Prop 65 Notice
