What does the .040 oversized specification mean for my engine?

The .040 oversized specification means these pistons are larger than the original factory size by 0.040 inches. Your engine's cylinders will need to be machined (bored) to this exact size to ensure a proper, tight fit for optimal performance and sealing.

Does this set include everything I need for the pistons?

Yes, this set includes both the pistons and the matching rings. This ensures that the rings are designed to work correctly with the pistons for proper cylinder sealing and oil control.

Can this part be shipped to California?

No, this piston set is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

This is a set of .040 oversized pistons and rings from Industrial Injection, specifically made for the 2003-2004 Dodge 5.9L 24V Cummins engine. If you're rebuilding the top end of your Ram 2500 or 3500 from these years, these pistons are a solid choice to get your engine back to spec, or even slightly larger if you're looking for a minor displacement increase during a rebuild.

Industrial Injection is known for their work with diesel engines, and this piston set is built to OEM specifications, but with a .040 inch oversize. This means they're designed to fit precisely into the cylinders of your Cummins engine, assuming the cylinders have been bored out to match this size. The set includes the pistons and the necessary rings, which is crucial for proper sealing and oil control. Having the rings included saves you a step and ensures compatibility with the pistons themselves. These are cast pistons, a common and reliable choice for many diesel applications, offering a good balance of performance and durability for everyday use and towing.

When you're undertaking an engine rebuild on your 2003-2004 Cummins, using parts that fit right and are made by a reputable diesel specialist like Industrial Injection can make a big difference. Remember that these pistons are .040 inches oversized, so your engine block cylinders will need to be machined to this dimension for a proper fit. This set is not CARB approved and cannot be shipped to California.
