Main Bearing Set - Dodge Cummins 5.9/6.7L

The Main Bearing Set for Dodge Cummins 5.9/6.7L engines is a critical rotating component engineered to support crankshaft loads under extreme diesel combustion pressures. This MAHLE ORIGINAL/CLEVITE bearing kit is designed for mechanics and engine builders who demand OEM-quality reliability in high-mileage rebuilds, performance modifications, or catastrophic engine failure repairs. Whether you're restoring a worn 24-valve or 6.7L platform, this bearing set ensures proper journal clearance and oil film integrity throughout the engine's operating range.

Manufactured to MAHLE's precision metallurgy standards, this P-Series bearing set features a 0.500 mm undersize geometry, making it ideal for crankshafts that have been line-bored or previously damaged. The undersize specification allows machinists to restore worn journals without full crankshaft replacement—a cost-effective solution for high-horsepower applications where stock clearances no longer meet tolerances. MAHLE's lead-tin lining and backing material provide superior conformability and embedability, crucial traits when running elevated boost pressures or nitrous oxide systems common in Cummins truck culture. Proper bearing selection prevents catastrophic spalling and maintains hydrodynamic oil pressure critical to long-term engine survival.

This complete kit suits both stock-rebuilt applications and modified engines pushing 500+ horsepower, provided journal work meets specification. Installation requires professional machine shop clearance verification and proper torque sequencing during block assembly. The 2.85 lb package contains all necessary main bearing shells for complete crankshaft support, streamlining the rebuild process and eliminating the risk of mixed-source bearing incompatibility. For Cummins owners serious about engine longevity, MAHLE ORIGINAL bearings represent the benchmark choice trusted by diesel performance shops nationwide.
