The Supertech Performance Complete Valvetrain Upgrade Kit delivers a premium, motorsport-grade solution for high-output engines operating at sustained high RPM and under extreme load. Featuring titanium retainers, Inconel exhaust valves, single-groove nitrided intake valves, and high-strength keepers, this kit is engineered to withstand rapid acceleration, elevated temperatures, and the increased cylinder pressures typical of big-turbo applications.

Whether you're building a high-revving track car or a competition-level street setup, Supertech’s proven reliability and precision machining make this valvetrain upgrade an essential foundation for achieving maximum performance. We strongly recommend Supertech components for any large-frame turbo build where durability and valve control are critical.
