What does the .020 oversize mean for my engine?

The .020 oversize indicates that these pistons are slightly larger than the original factory size by 0.020 inches. This is typically used when the engine cylinders have been machined (bored) to remove wear or damage, allowing for a fresh, tight seal.

Does this set include everything needed for the pistons?

Yes, this set comes complete with both the pistons and the necessary rings. This means you'll have the core components ready for installation into your engine block.

Can I use these pistons if my engine hasn't been bored?

These pistons are specifically designed for engines that have been bored to a .020 inch oversize. If your engine cylinders are still at standard bore size, you would need a standard size piston set instead.

About this part

Product Details

If you're rebuilding the engine in your 2003-2004 Dodge 5.9L Cummins, getting the right pistons is key to a solid rebuild. This set from Industrial Injection is designed to replace your original pistons with a .020 inch oversize, perfect for engines that have been bored out to correct wear or damage.

These pistons are made to OEM specifications, meaning they'll fit right and perform as expected. They come complete with rings, so you have everything you need to get your engine back in running order. The .020 oversize is a common choice when the cylinder walls have seen some miles and need a little extra clearance to seal properly. This helps ensure good compression and oil control, which are crucial for the longevity and performance of your Cummins engine.

When you're putting an engine back together, especially a powerful diesel like the Cummins, using well-made components is important. This piston and ring set is a solid option for anyone looking to restore their engine's performance and reliability. Make sure to check your engine's bore size before ordering to confirm the .020 oversize is the correct fit for your specific rebuild needs.
