Valve Features:

• Enhanced Engine Efficiency: Improved airflow leads to better engine breathing, resulting in greater power output and overall engine efficiency in both turbocharged and naturally aspirated setups.
• Back Cut Design: Strategically crafted to optimize air flow, allowing your engine to achieve higher RPMs and improved performance across the powerband.
• Micro-Polished Valve Stems: Minimizes oil retention on the valve stem, significantly reducing friction and drag, ensuring smoother motion within the valve guide for improved efficiency and longevity.
• Stainless Steel Construction: Designed to withstand extreme temperatures, especially in turbocharged and supercharged engines, ensuring consistent performance and durability under high-stress conditions.
• Hardened Valve Tips: The valve tips are reinforced using a mid-stem friction weld process to extend valve life and minimize wear, ensuring optimal contact with the rocker.
• OEM Keeper/Lock Compatibility: Designed to work seamlessly with OEM triple groove keeper/lock systems. While compatible, we recommend not reusing old valve locks in performance applications to avoid the risk of material grooving.
• GSC Power Division Quality: Backed by GSC Power Division's commitment to delivering top-tier quality and performance, ensuring that every valve meets the highest standards in the industry.
