Product Description

The MAHLE 2243523WR is a standard-bore piston set designed for specified 5.9L 12-valve Cummins B-Series diesel applications in 1991-1993 Dodge D250, D350, W250, and W350 trucks. The piston uses an aluminum construction and bowl-style crown designed for the applicable Cummins engine configuration. Its standard-bore specification makes it appropriate for engines that remain at the original bore dimension and meet the required piston-to-cylinder clearances.

This MAHLE piston set incorporates compensated ring-groove geometry and an expansion-controlled design to support proper ring loading, oil control, operating clearances, and long-term durability. The package includes pistons, rings, wrist pins, and retaining clips, providing the primary piston components needed during an engine rebuild. Verify cylinder bore, piston bowl configuration, wrist-pin dimensions, and engine specifications before assembly to ensure complete compatibility.
