Performance Features:
Constructed from high-grade, heat-resistant stainless steel, these valves are built to withstand the rigors of high RPMs and extreme conditions. The innovative undercut shaft design above the head area not only minimizes weight, enhancing rotational potential, but also significantly boosts airflow to and from the combustion chamber. This results in improved combustion efficiency and overall engine performance.

Each valve undergoes a rigorous machining process, culminating in a spin-polished finish beneath the head. This attention to detail not only enhances aesthetics but also contributes to smoother operation and reduced friction, further optimizing performance.
