Prepare Your Cummins For The Next Level Of Performance

When your engine rebuild calls for more than factory replacement parts, the Industrial Injection X-Series Coated and Chamfered .020 Piston Kit is ready to step up. Designed for 1998.5-2002 5.9L Cummins 24V engines that have been machined for a .020 inch oversize bore, this piston kit combines proven durability with performance focused upgrades. The thermal barrier coating helps control piston temperatures under demanding conditions, while the low friction anti scuff skirt coating promotes smoother operation and reduced wear over thousands of miles. Additionally, the chamfered piston tops help reduce cylinder wall scuffing, making these pistons an excellent choice for trucks that tow heavy or operate under increased boost. The .015 inch reduced compression height provides added flexibility for more demanding engine combinations without sacrificing the reliability expected from a quality rebuild. Every matched piston kit includes rings, wrist pins, and clips, giving you the essential components needed to complete your project with confidence. Whether your truck is built to haul, tow, or make reliable power every day, this piston kit is designed to help your Cummins perform at its best.

Built With Upgrades That Support Demanding Engine Builds

The Industrial Injection X-Series Coated and Chamfered .020 Piston Kit is engineered for builders who need an oversize piston with features that support higher cylinder pressures and elevated boost levels. Manufactured specifically for 1998.5-2002 5.9L Cummins 24V 6BT engines requiring a .020 inch overbore, each matched piston is designed to deliver consistent fitment throughout the engine. Furthermore, the thermal barrier coating on the piston crown helps reduce heat transfer into the piston, while the anti scuff skirt coating minimizes friction between the piston and cylinder wall. Chamfered piston tops further improve durability by helping reduce the potential for cylinder wall scuffing during demanding operation. The .015 inch reduced compression height makes this piston well suited for performance oriented diesel builds that require additional combustion chamber clearance. Every kit is supplied with matching rings, wrist pins, and retaining clips to simplify engine assembly and ensure component compatibility. Before installation, verify your final bore size, compression height requirements, and overall engine specifications to ensure this piston kit matches your rebuild plan.
