Main Bearing Set Ford 6.0L Diesel

The Main Bearing Set Ford 6.0L Diesel is engineered for mechanics and diesel enthusiasts who demand factory-backed reliability in their PowerStroke rebuild. Whether you're restoring a high-mileage engine or upgrading after catastrophic bearing wear, this MAHLE ORIGINAL/CLEVITE kit delivers OEM-quality performance that matches Ford's exacting standards. The 6.0L PowerStroke—notorious for bearing stress under aggressive tuning and towing—requires precision bearing geometry to maintain crankshaft clearances and oil film integrity.

This bearing set features a 0.750 mm undersize specification, which corrects crankshaft journals that have been polished or are worn beyond standard tolerance. The P-series design incorporates tri-metal bearing construction—a steel backing layer, copper-lead intermediate layer, and babbit overlay—that distributes load evenly while resisting micro-welding under extreme combustion pressures. MAHLE ORIGINAL's precision manufacturing ensures tight tolerances on both bore and back diameter, critical for preventing bearing spin and maintaining adequate oil clearance; improper clearance leads to starvation or excessive blow-by.

This bearing kit is essential for any 6.0L PowerStroke rebuild, whether you're addressing factory defects or recovering from tune-induced bearing failure. Installation requires proper crankshaft polishing to the 0.750 mm undersize specification and adherence to Ford torque specs during assembly; mixing bearing sizes or reusing old crankshafts invites early failure. Pair this set with quality oil analysis and maintenance intervals to maximize bearing life in stock or lightly modified engines.
