Advanced Piston Technology For Oversize Engine Rebuilds

The Industrial Injection 245119 ISB X-Series Coated and Chamfered Piston Kit is engineered 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 .040 inch oversize bore. Manufactured as a matched piston set, these pistons provide consistent fitment across every cylinder to support balanced engine operation during assembly. The thermal barrier coating applied to the piston crown is designed to help manage combustion temperatures, while the low friction anti scuff skirt coating reduces contact between the piston and cylinder wall. Additionally, the chamfered piston tops help reduce cylinder wall scuffing during demanding operating conditions. Each piston features a .015 inch reduced compression height, making this kit well suited for increased boost levels, higher cylinder pressure, and heavy towing applications. The complete kit also includes piston rings, wrist pins, and retaining clips, eliminating the need to source those critical components separately. For builders looking to pair a .040 inch oversize rebuild with enhanced durability and proven engineering, this Industrial Injection piston kit delivers the performance and reliability needed for demanding diesel applications.
