What does the .040 sizing mean for these pistons?

The .040 sizing indicates that these pistons are 0.040 inches larger in diameter than the standard bore size for your engine. This is typically used when an engine block has been bored out to correct wear or to increase displacement.

Do these pistons come with everything needed for installation?

Yes, this set includes six pistons with the piston rings already mounted. It also comes with the necessary wrist pins and clips, making them ready for installation into your engine.

Are these pistons suitable for all 5.9L Cummins engines?

This specific piston set is designed for the 5.9L ISB diesel engine found in the 2001-2002 Dodge Ram 2500 and 3500 models. Always confirm your engine's exact model and year to ensure compatibility.

Product Details

If you're rebuilding the engine in your 2001 or 2002 Dodge Ram 3500 with the Cummins 5.9L ISB diesel, this Mahle OE piston and ring set is a solid choice. These are the same type of pistons that came from the factory, designed to meet the specific demands of that 6-cylinder engine. They are built to ensure proper ring loading and effective oil control, which helps reduce engine noise and emissions while improving overall oil management.

Mahle is a major OE piston manufacturer, so you know you're getting parts that are made to the original specifications. This set includes six pistons, each already fitted with its rings, along with the necessary pins and clips. This means they are ready to install right out of the box, saving you time and hassle during your engine build. The pistons are also designed with expansion control, allowing for tight clearances that further minimize noise and wear.

Because these are OE-quality replacements, they are designed to fit right and perform as expected in your Cummins 5.9L ISB engine. The .040 sizing indicates these are 0.040 inches larger than standard bore size, which is important to note if you've already had machine work done on your block. Remember that this set is not CARB approved and cannot be shipped to California.
