Build With Confidence When Every Detail Matters

When you are putting together a serious Cummins engine, every component needs to support the power and reliability you expect. The Industrial Injection X-Series Fly Cut Coated and Chamfered .020 Piston Kit is designed for 1998.5-2002 5.9L Cummins 24V engines that have been machined for a .020 inch overbore, giving you a piston that is ready for demanding applications. The .100 inch fly cut valve reliefs provide valuable piston to valve clearance for builds using higher lift camshafts or upgraded valvetrain components. Additionally, the thermal barrier coating helps control combustion heat while the low friction anti scuff skirt coating reduces friction and promotes long term durability. Chamfered piston tops help minimize cylinder wall scuffing, making this kit a smart choice for trucks that spend their lives towing heavy loads or producing increased horsepower. Every matched piston kit includes rings, wrist pins, and clips, so you have the essential components needed to complete your rebuild with confidence. If your goal is to build an engine that is prepared for both performance and durability, this piston kit offers the upgrades to help make it happen.

Purpose Built Components For High Output Diesel Engines

The Industrial Injection X-Series Fly Cut Coated and Chamfered .020 Piston Kit combines advanced piston design with features intended for performance focused 1998.5-2002 5.9L Cummins 24V 6BT engine builds. Manufactured as a matched piston set for engines requiring a .020 inch oversize bore, these pistons provide consistent fitment and balanced operation throughout the rotating assembly. Furthermore, each piston features a thermal barrier coated crown that helps reduce heat transfer into the piston during high load operation, while the anti scuff skirt coating minimizes friction against the cylinder walls. The .015 inch reduced compression height provides additional clearance for elevated boost and increased cylinder pressure, making these pistons well suited for more demanding engine combinations. Integrated .100 inch fly cut valve reliefs provide the extra piston to valve clearance needed when running higher lift camshafts or modified valvetrain components. The kit also includes matching rings, wrist pins, and retaining clips, helping streamline assembly with components engineered to work together. Before installation, verify that your engine has been machined for a .020 inch overbore and confirm all clearance requirements to ensure compatibility with your specific engine build.
