Build Your Oversize Cummins For Lasting Strength

Every successful engine rebuild starts with components that are ready to work as hard as the truck they are installed in, and the Industrial Injection X-Series Coated and Chamfered .020 Piston Kit delivers exactly that. Designed for 2003-2004 5.9L Cummins engines machined .020 inch over, this piston kit offers a combination of durability and performance focused enhancements that go beyond a standard replacement. The thermal barrier coating helps control combustion heat, while the low friction anti scuff skirt coating is engineered to reduce friction and promote smoother piston travel over the life of the engine. Chamfered piston tops also help reduce cylinder wall scuffing, giving your rebuild added protection during heavy towing and demanding driving conditions. Every matched piston set includes rings, wrist pins, and clips, making it easier to complete your engine build with confidence and fewer additional parts to source. Furthermore, the reduced compression height makes these pistons well suited for applications running elevated boost and increased cylinder pressure. If you want your .020 inch oversize Cummins rebuild to be prepared for years of dependable performance, this Industrial Injection piston kit is built to deliver.

Precision Designed For Demanding Oversize Applications

The Industrial Injection 244121 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 upgrades intended for performance oriented diesel engine builds. Each piston features a thermal barrier coating on the crown that helps manage combustion temperatures, while the low friction anti scuff skirt coating is designed to reduce piston skirt wear against the cylinder wall. Additionally, the chamfered piston tops help reduce cylinder wall scuffing during demanding operating conditions, improving long term durability. The .015 inch reduced compression height supports applications operating with elevated boost levels, increased cylinder pressure, and heavy towing demands. Every kit includes matching piston rings, wrist pins, and retaining clips to simplify installation and maintain proper component compatibility throughout the rebuild. For builders seeking premium oversize pistons that combine proven fitment with enhanced thermal protection and durability, this X-Series piston kit delivers the performance and reliability expected from Industrial Injection.
