Are you rebuilding a Duramax? Industrial Injection X Series Piston Kits are engineered to provide the strength, reliability, and long-term durability needed for everything from stock rebuilds to performance-focused applications. Available in both standard X Series and Coated De-Lipped X Series configurations, these piston kits are designed to help your engine withstand the demands of towing, daily driving, and high-performance use. With Standard, .020", .030", and .040" oversize options available, finding the right fit for your build is simple while gaining the confidence that comes from using components trusted throughout the diesel industry.
Built as precision-balanced matched sets, each kit includes pistons, rings, wrist pins, and retaining clips for a complete installation. Coated De-Lipped X Series Pistons feature a thermal barrier crown coating that helps keep combustion heat where it belongs, improving efficiency and power output. At the same time, ceramic-coated skirts reduce friction and provide added protection against wear and scuffing. The de-lipped piston design helps reduce heat concentration around the combustion bowl, promoting improved durability under elevated cylinder pressures and temperatures. Select applications also feature premium PVD-coated ring packs that enhance sealing, oil control, and overall longevity. Whether you're restoring reliability or building for more power, Industrial Injection X Series Pistons are designed to handle the demands of serious diesel performance.
What Piston Set Is Right For You?
Stock Piston Kit: Perfect for OEM-style rebuilds while delivering improved reliability and performance over standard replacement pistons.
Coated De-Lipped: Designed for high-performance diesel engines running increased fuel delivery, elevated boost levels, and demanding towing applications.
