What does '.020 oversized' mean for these pistons?

'.020 oversized' means these pistons are 0.020 inches larger in diameter than the original factory specification. This size is used when the engine's cylinders have been machined (bored and honed) to remove wear or damage and achieve a fresh, clean surface for the new pistons.

Are the piston rings included with this set?

Yes, this set includes the necessary piston rings that are specifically matched to the .020 oversized pistons. Proper ring installation is critical for engine performance and oil control.

What other parts are typically needed for a piston replacement job?

Beyond the pistons and rings, a complete engine rebuild often requires new bearings (rod and main), gaskets and seals, oil pump, coolant, and potentially cylinder head work. It's recommended to consult your vehicle's service manual or a professional mechanic for a full parts list.

About this part

Product Details

This is a set of .020 oversized pistons and rings from Industrial Injection, specifically made for the 2003-2004 Dodge Ram 2500 and 3500 models equipped with the 5.9L 24V Cummins engine. If you're rebuilding the top end of your engine, whether due to wear or to achieve a specific bore size, these pistons are designed to fit right into the cylinders with a .020 inch overbore. This size is often chosen when the original cylinder walls have been honed or machined to remove imperfections and restore proper sealing.

Industrial Injection is known for its focus on diesel performance and repair parts. These pistons are cast and then machined to precise tolerances, ensuring they meet the demands of a heavy-duty diesel engine. The set includes the necessary rings, which are crucial for proper cylinder sealing, oil control, and heat transfer. Having the correct size rings matched to the pistons is essential for optimal engine performance and longevity after a rebuild. This kit is intended for a direct replacement scenario where the cylinders have already been bored to the .020 inch oversize specification.

When undertaking an engine rebuild of this magnitude, it's important to have all necessary components ready. Ensure your machine shop has confirmed the correct cylinder bore measurement before ordering. This piston and ring set is a solid option for restoring the integrity of your 5.9L Cummins engine's combustion chambers.
