Looking for a piston upgrade that can handle the demands of your Duramax without sacrificing reliability? Industrial Injection X Series Piston Kits are designed for builders who want confidence, whether they're refreshing a high-mileage engine or assembling a performance-focused build. Available in both standard X Series and Coated De-Lipped X Series options, these piston kits provide the durability needed to withstand increased cylinder pressures, elevated boost levels, and demanding towing conditions. With Standard, .020", and .040" oversize options available, they're an excellent choice for everything from routine rebuilds to engines built for significantly more power than stock.
Each X Series Piston Kit is manufactured as a precision-balanced matched set and includes pistons, rings, wrist pins, and retaining clips. Coated De-Lipped variants feature advanced thermal barrier crown coatings that help improve combustion efficiency by retaining heat within the combustion chamber. At the same time, the ceramic-coated skirts reduce friction and help protect against wear during heavy-duty operation. The de-lipped piston design helps distribute heat more effectively, reducing stress in critical areas of the piston under extreme operating conditions. Select applications also include premium PVD-coated ring packs that offer improved sealing, superior oil control, and increased durability. Engineered to meet the demands of hardworking diesel trucks, Industrial Injection X Series Pistons deliver the strength and protection needed for years of dependable performance.
