Build Your Bottom End With Strength You Can Trust

When you're building a Cummins for real-world power, you can't afford to cut corners on pistons. The Industrial PDM-3732CC.020 Oversized Coated Piston Set is designed to handle the kind of heat and pressure that stock parts just can't survive. Whether you're running high boost, nitrous, or simply pushing the truck harder than factory specs ever intended, these pistons give your engine the reliability and performance edge it needs. The thermal barrier coating helps keep heat where it belongs, in the combustion chamber, so you get more energy out of every stroke. Add in a ceramic-coated skirt that reduces friction and wear, and you've got a setup built to thrive under extreme conditions. These pistons drop in with no extra machining required and come complete with rings, wrist pins, and clips, taking the guesswork out of the install. If your truck sees towing, tuning, or track time, this is the kind of upgrade that pays off in both power and peace of mind.

Coated To Withstand Heat Load And High Stress

The PDM-3732CC.020 piston set is engineered for Cummins owners who demand more from their builds. Designed for 2007.5 to 2016 6.7L engines, these pistons feature a .020 oversize for rebuilds that require a fresh bore. Each piston includes a thermal barrier coating on the crown, specifically developed for engines using forced induction or high fuel volumes. This coating keeps combustion heat in the chamber longer, improving torque and overall efficiency. The skirt is coated with a ceramic film capable of handling over 350,000 PSI in load while maintaining lubricity at temperatures exceeding 1600 degrees Fahrenheit. These coatings are just one part of the equation, the pistons are also flycut with .100 valve reliefs to accommodate high-lift camshafts and chamfered at the top to reduce swelling and prevent scuffing during high-load operation. Despite the advanced design, the coated film is thin enough to maintain OEM piston-to-wall clearance, making installation straightforward for engine builders. This kit provides a serious internal upgrade for Cummins trucks running more power, more heat, and more stress than stock.
