Take your Cummins valvetrain to the next level. This kit is designed for built and higher-horsepower Cummins applications where the factory valvetrain can become a limiting factor.
Upgrading the head and valvetrain helps support higher RPM, increased boost, and higher power levels while providing improved valvetrain stability and reliability. Whether you're building a strong street truck, tow rig, or competition setup, this package gives you the upgraded components needed when pushing your Cummins beyond stock power levels.
