Give Your Rebuild A Strong Foundation For The Road Ahead

A quality engine rebuild starts with components you can trust, and the Industrial Injection 24T103 ISB X-Series .020 Piston Kit is built with exactly that goal in mind. Designed for 2007.5-2018 6.7L Cummins 24V ISB engines, this matched piston set provides the confidence needed when rebuilding an engine with a .020 inch overbore. Every kit includes the pistons, rings, wrist pins, and retaining clips, giving you the essential parts required for a complete piston installation. The low friction anti scuff skirt coating helps reduce friction and wear, allowing the pistons to move smoothly through the cylinders during daily operation. Additionally, this kit is an excellent choice for trucks that spend their time towing, hauling, or covering countless highway miles. Its drop in replacement design keeps the rebuild process straightforward while maintaining the dependable performance expected from a stock style piston. When reliability is your priority, this piston kit delivers the quality and fit needed to get your Cummins back to work.

Built For Precision In Every Engine Rebuild

The Industrial Injection X-Series .020 Oversize Piston Kit is engineered specifically for 2007.5-2018 6.7L Cummins 24V ISB engines that have been machined to accept a .020 inch overbore. Each matched piston is manufactured to work with the included piston rings, wrist pins, and clips, helping simplify engine assembly while maintaining proper component compatibility. Furthermore, the low friction anti scuff skirt coating reduces piston skirt wear and promotes smooth movement against the cylinder walls throughout the engine's operating range. The drop in replacement design follows factory specifications for stock replacement applications, making it a practical solution for professional engine builders and experienced enthusiasts alike. Because this is an oversize piston kit, it is intended for rebored engine blocks rather than standard bore cylinders. Before installation, verify the finished bore size and all engine clearances to ensure the pistons match your specific build and provide long term durability.
