Prepare Your Oversize Cummins For Serious Work

A properly machined engine deserves pistons that are ready for the demands of modern diesel performance, and the Industrial Injection X-Series Coated and Chamfered .020 Piston Kit is built with exactly that purpose in mind. Designed for 2003-2004 5.9L Cummins engines bored .020 inch over, this kit combines proven stock replacement fitment with upgrades that help support tougher operating conditions. The thermal barrier coating helps protect the piston crown from intense combustion heat, while the low friction anti scuff skirt coating is engineered to reduce wear and promote smooth piston movement. Chamfered piston tops provide an additional layer of protection by helping reduce cylinder wall scuffing during demanding use. Every kit includes matched pistons, rings, wrist pins, and clips, making it easier to complete your rebuild with confidence and fewer additional parts to source. Furthermore, the reduced compression height makes these pistons an excellent choice for trucks running elevated boost, heavy towing loads, or performance focused engine combinations. If your goal is a durable .020 inch oversize rebuild that is ready to work as hard as your truck does, this Industrial Injection piston kit is an outstanding choice.

Advanced Piston Design For Oversize Performance Builds

The Industrial Injection 244116 ISB X-Series Coated and Chamfered Piston Kit is engineered specifically for 2003-2004 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 install as direct drop in replacements while incorporating several performance oriented enhancements beyond a conventional stock 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 is designed to reduce friction between the piston and cylinder wall during operation. Additionally, the chamfered piston tops help reduce cylinder wall scuffing, contributing to improved durability under higher cylinder pressures. The .015 inch reduced compression height makes this piston kit well suited for engines operating with elevated boost and demanding towing conditions. Every kit includes matching piston rings, wrist pins, and retaining clips to simplify installation and ensure proper component compatibility throughout the rebuild. For builders looking to combine a .020 inch oversize engine restoration with proven performance upgrades, this X-Series piston kit delivers the durability, thermal protection, and precision expected from Industrial Injection.
