What does the .040 sizing mean for these pistons?

The .040 sizing indicates that these pistons are larger in diameter than the original factory pistons by 0.040 inches. This is typically used when the engine cylinders have been bored out to match this larger size during an engine rebuild.

Are these pistons suitable for a stock rebuild or a performance build?

These cast pistons from Industrial Injection are a well-built option that can be used for both stock-replacement rebuilds and many performance applications. Their .040 sizing is common for engines that have had their cylinders bored out.

What else might I need when installing these pistons?

When installing new pistons, it's essential to have your engine block professionally machined to the correct bore size. You will also need new piston rings, connecting rod bearings, and potentially new wrist pin bushings, along with all necessary gaskets and seals for a complete engine overhaul.

About this part

Product Details

This is a set of .040 inch oversized cast pistons from Industrial Injection, specifically made for the 2004 through 2007 Dodge Ram 2500 and 3500 models equipped with the 24-valve Cummins engine. If you're rebuilding the top end of your engine, whether due to wear or to achieve a specific performance goal, a quality piston set is fundamental to the entire build. These pistons are designed to replace your original equipment pistons, but with an increased bore diameter to account for machining or to slightly increase displacement.

Industrial Injection has been in the diesel performance game for a long time, and they know what it takes to build reliable components. These cast pistons are a solid option for many rebuilds. The .040 inch sizing means they are intended for use after the cylinders have been bored out to match this dimension, ensuring a proper seal and optimal performance. This set includes all the pistons you'll need to complete your engine's cylinder work, providing a well-built foundation for your diesel's power plant.

When undertaking an engine rebuild of this magnitude, it's crucial to have all your components ready. Ensure you have the correct machining done on your engine block to accept these oversized pistons. Always refer to the manufacturer's detailed installation instructions and torque specifications to ensure a successful rebuild. This piston set is a key component for getting your 24-valve Cummins back in top running condition.
