Product Details

When you're rebuilding the top end of your 1994-1998 Dodge Ram 2500 with the Cummins B 5.9L L6 engine, getting the right pistons is crucial. This set from Mahle OE gives you six pistons, each .020 inch undersize, complete with their matched rings, pins, and clips. Mahle is a major OE piston manufacturer, so you know these parts are built to the same standards as what came from the factory.

These pistons feature compensated ring grooves, which help ensure the rings load correctly and maintain good oil control. They also have expansion-controlled designs. This means they're made to fit with minimal clearance, which helps reduce engine noise, wear, and emissions, all while improving how well the engine manages its oil. Having the rings pre-mounted, along with the included pins and clips, means these pistons are ready to go right out of the box, saving you time and hassle during your rebuild.

This set is designed as a direct replacement for your Cummins B 5.9L engine. Remember that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
