Complete Piston Kit for 5.9L Cummins

When you’re rebuilding a 12-valve Cummins and want it to not only survive but thrive under serious power, the Industrial Coated Pistons are exactly the kind of upgrade you want in your engine. Built for 1989–1998 RAM 2500 and 3500 trucks, these .040 oversized pistons are designed to handle high horsepower, high heat, and the kind of abuse that would leave a stock setup begging for mercy. Right out of the box, you’ll notice a few key features that set these pistons apart. First, the tops are chamfered—a small but critical detail. By tapering the piston edges, Industrial helps reduce swelling at high temperatures, which cuts down on the risk of scuffing the cylinder walls during heavy loads and high RPMs. It’s a smart, preventative design move that helps extend both piston and cylinder life in performance applications.

High-Quality Construction & Design

Then there’s the serious coating work. The tops are treated with a thermal barrier coating, specifically designed for engines running lots of fuel, high compression, nitrous, superchargers, or big turbo setups. This coating helps keep more heat inside the combustion chamber where it belongs, rather than letting it bleed into the piston and cylinder walls. The result is better combustion efficiency, stronger torque, and more horsepower across the board—perfect for a truck that’s built to make power and work hard. The skirts aren’t overlooked either. Each piston features a ceramic skirt coating that’s made to handle extreme pressure and friction—up to 350,000 PSI and temperatures over 1600°F. This coating creates a tough, low-friction surface that reduces wear and keeps your pistons moving smoothly even in the harshest environments. It’s the kind of protection that pays off in longevity and reliability, especially if you're planning to run your truck hard or push it into competition territory.

Complete Kit

Each kit comes complete with six pistons, plus rings, wrist pins, and clips, making it a true drop-in solution for a full rebuild. Whether you’re freshening up an old workhorse, building a competition truck, or just making sure your Cummins is ready for the next decade of hard use, the Industrial PDM-03513CC.040 Coated Pistons give you the peace of mind that only comes with top-tier parts.
