GSC POWER-DIVISION Stainless Steel Exhaust Valves [HEAD DIAMETER 28.5MM | TOTAL LENGTH 97.5MM | STEM DIAMETER 5.46MM] (NISSAN 3.0L VR30DDTT V6)

When creating our valves we set out to create the best performance, longest lasting valves available to the aftermarket. Using advanced 3D design and simulation software, we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available on the market. With the materials used, we have less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve.

Valve Features:

• Enhanced Engine Efficiency: Improved airflow leads to better engine breathing, resulting in greater power output and efficiency.
• Back Cut Design: Strategically improves air flow, enabling higher RPMs,
• Micro-Polished Valve Stems: Minimizes oil retention on the stem, reducing drag for a smoother motion within the guide.
• Premium Material: Exhaust valves are crafted from modified 23-8n stainless steel for exceptional strength and performance.
• Valve Tips: Hardened or fused with a stellite wafer tip, ensuring extended life and minimal wear, maintaining proximity to the rocker or valve tappet.
• Compatibility: Our valves seamlessly work with OEM keeper/lock systems. While not mandatory, we advise against reusing any valve locks on performance applications due to potential material grooving.
• Quality: Backed by GSC Power-Division's commitment to quality and performance.
