Piston Pin Bushing Dodge Cummins B Series

The Piston Pin Bushing Dodge Cummins B Series is a precision-engineered wrist pin bushing designed for the 5.9L Cummins diesel engine found in Dodge B-series trucks. This critical internal component serves as a load-bearing interface between the piston pin and connecting rod, enabling smooth articulation under extreme combustion pressures and engine speeds. Heavy-duty diesel operators and engine rebuilders rely on OEM-quality piston pin bushings to maintain proper bearing clearance, reduce wear, and ensure reliable long-term engine performance.

Manufactured by MAHLE ORIGINAL/CLEVITE, this bushing features a 1.554-inch inner diameter paired with a 1.692-inch outer diameter and 1.510-inch length, precisely machined to factory specifications. The steel construction with natural finish delivers the durability and dimensional accuracy required for proper pin fit and connecting rod alignment. The bushing's low friction characteristics allow the piston pin to rotate freely while distributing combustion loads evenly across the contact surface, preventing galling and premature failure during high-load diesel operation.

Professional engine rebuilders and Dodge Cummins enthusiasts choose this MAHLE component for complete short-block assembly, full overhauls, or bearing wear correction. Installation requires removal of the piston and connecting rod assembly, making this bushing part of a comprehensive rebuild project rather than a standalone service item. The Piston Pin Bushing Dodge Cummins B Series is sold as a single unit and must be properly installed with correct clearance specifications to ensure the durability of your 5.9L engine investment.
