What does '.040 oversized' mean for these pistons?

'.040 oversized' means these pistons are 0.040 inches larger in diameter than the original factory pistons. This indicates they are intended for an engine block that has been bored out by 0.040 inches to accommodate them, typically done during an engine rebuild to restore cylinder integrity or increase displacement.

Does this piston set come with everything needed for installation?

This set includes the pistons and the matching piston rings. It does not include other engine components like bearings, gaskets, or seals, which are typically replaced during an engine rebuild and should be sourced separately.

Can these pistons be shipped to California?

No, these pistons are 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 with rings for your 2003-2004 Dodge Ram 2500 or 3500 equipped with the 24V Cummins engine. Industrial Injection is known for making solid engine components, and this piston set is built to handle the demands of a Cummins diesel. If you're rebuilding the top end of your engine, whether it's due to wear or you're looking to bring it back to factory specifications with a slight bore increase, these pistons are a well-made option.

These pistons are cast from high-quality aluminum and are precisely sized at .040 inches larger than stock. This means they are designed to be installed in an engine block that has been bored out by .040 inches. The included rings are matched to the pistons to ensure a proper seal between the piston and the cylinder wall, which is critical for compression and oil control. Having a good seal helps maintain engine performance and longevity. This set is designed as a direct replacement for OEM specifications, but with the oversized bore, it's important to ensure your engine block is properly machined to the correct tolerance before installation.

When undertaking an engine rebuild of this magnitude, it's always recommended to consult the manufacturer's installation instructions and ensure all related components, such as bearings, gaskets, and seals, are also in good condition or replaced. This piston and ring set is a key component for restoring or enhancing the performance of your 24V Cummins engine.
