What exactly is included in this piston and ring set?

This Mahle OE set includes six pistons, six sets of matched piston rings, six piston pins, and six sets of piston pin clips. Everything needed to install the pistons in your engine's cylinders is provided.

What does the '.040' designation mean for these pistons?

The '.040' indicates that these pistons are 0.040 inches larger in diameter than the standard factory size. This means they are intended for use in engine cylinders that have been bored out to a 0.040 inch oversize to clean up wear or damage.

Are these pistons ready to install right away?

Yes, Mahle OE pistons come with the piston rings already mounted on the pistons. The set also includes the necessary piston pins and clips, making them ready for installation by the engine builder.

Product Details

When you're rebuilding the engine in your 1994-1998 Dodge Ram 2500 or 3500 with the Cummins B 5.9L L6, getting the right pistons and rings is crucial. This set from Mahle OE gives you everything you need to get those cylinders sealed up tight. You'll receive six pistons, each with compensated ring grooves for proper ring loading and oil control, along with the matched piston rings. Mahle also includes the piston pins and clips, so these are ready to install right out of the box, saving you time and hassle during your build.

Mahle OE pistons are built to the same standards as the original equipment, meaning they have features like expansion-controlled designs. This helps them maintain small fitting clearances, which can reduce engine noise, wear, and emissions, while also improving oil control. As one of the largest OE piston manufacturers globally, Mahle has a deep understanding of what it takes to make a reliable engine component. This set is specifically sized at .040 inch undersize, which is important if you're re-boring your cylinders to that specific dimension.
