Product Details

When you're rebuilding the heart of your 1994-1998 Dodge Ram 2500 with the Cummins B 5.9L L6 engine, starting with well-made pistons is crucial. These Mahle OE piston sets come with compensated ring grooves, a design that helps ensure the rings seat properly and control oil effectively. This attention to detail means you're getting a part that's built to the same standards as the original equipment your truck came with.

Mahle has engineered these pistons with expansion-controlled designs. What this means for your engine is tighter fitting clearances, which helps reduce noise during operation, lowers wear on internal components, and contributes to better emissions control and oil management. You'll receive a complete set of six pistons, each ready for installation with the piston rings already mounted. The necessary pins and clips are also included, saving you time and hassle when you're putting your engine back together. Mahle is one of the largest original equipment piston manufacturers globally, so you can be confident in the quality and fit.

This set is designed for a standard bore, meaning it's intended for engines where the cylinders haven't been significantly overbored or worn down. Always refer to your engine's service manual for specific installation procedures and torque specifications. Please note that this part is not CARB approved and cannot be shipped to California.
