Build Your Oversize Cummins Without Holding Back

A performance rebuild is the perfect opportunity to install components that are ready for the extra demands your engine will face, and the Industrial Injection X-Series Fly Cut Coated and Chamfered .020 Piston Kit was designed with exactly that purpose in mind. Built for 2004.5-2007 5.9L Cummins engines that have been machined for a .020 inch oversize bore, this piston kit combines durability, thermal protection, and additional valve clearance in one complete package. The thermal barrier coating helps protect the piston from intense combustion heat, while the low friction anti scuff skirt coating is designed to minimize wear during everyday driving and high load conditions alike. The .100 inch fly cut valve reliefs provide the additional clearance needed for engines equipped with higher lift camshafts, giving you more flexibility when planning your build. Every kit also includes matched pistons, rings, wrist pins, and clips, making it easier to complete your rebuild with confidence. Whether your truck spends its time pulling heavy trailers, making big power on the street, or tackling demanding work every day, these pistons are built to keep up. When reliability and performance matter equally, this Industrial Injection piston kit is a smart investment for your Cummins engine.

Engineered For Modified Oversize Performance Applications

The Industrial Injection 245123 ISB X-Series Fly Cut Coated and Chamfered Piston Kit is engineered specifically for 2004.5-2007 Dodge Ram 2500 and 3500 models equipped with the 5.9L Cummins 24 valve ISB engine that has been machined for a .020 inch oversize bore. Manufactured as a matched piston set, these pistons provide consistent fitment while incorporating several performance oriented design enhancements over a conventional replacement piston. Each piston features a thermal barrier coating on the crown to help manage combustion temperatures, along with a low friction anti scuff skirt coating that reduces friction between the piston and cylinder wall. Additionally, chamfered piston tops are designed to help reduce cylinder wall scuffing, while the .015 inch reduced compression height supports applications operating with increased cylinder pressure and elevated boost. Integrated .100 inch fly cut valve reliefs provide additional piston to valve clearance, making this kit an excellent choice for engines using higher lift camshafts or requiring extra valvetrain clearance. Every kit includes matching piston rings, wrist pins, and retaining clips to simplify installation and ensure component compatibility. For builders looking to maximize the potential of a .020 inch oversize Cummins rebuild, this Industrial Injection piston kit delivers the durability, clearance, and precision needed for demanding diesel performance.
