Description
If you're running your engine hard at high RPM, OEM valve and spring components become a limiting factor—they simply weren't engineered to handle sustained extreme conditions. The PROX 28.SIS4341-2 Kit replaces those weak points with purpose-built steel valves and premium spring geometry that work together to eliminate valve float, reduce wear, and unlock the full potential of your build. Whether you're on the track or pushing limits on the dyno, this kit delivers the durability and reliability that separates a well-engineered engine from one that fails.

- Increased durability/wear resistance
