GSC P-D Mitsubishi 4G63T Extreme Pressure Conical Valve Spring and Ti Retainer Kit

This is the GSC Power Division 5097 Extreme Pressure Conical Valve Spring and Titanium Retainer Kit, specifically made for the Mitsubishi 4G63T engine. If you're building a high-performance 4G63T and need to handle increased camshaft lift and aggressive RPMs, this kit is a solid choice. It's designed to keep your valves under control even when you're pushing the engine hard.

What sets this kit apart is the extreme pressure design of the conical valve springs. Conical springs are lighter than traditional dual springs, which reduces valve float at higher RPMs. The 'extreme pressure' rating means they're built to handle the demands of aggressive camshaft profiles and higher boost levels without losing their ability to close the valves reliably. This is crucial for preventing engine damage when you're running your engine at its limits. The kit also includes titanium retainers, which are significantly lighter than steel retainers. This weight reduction further helps in reducing valve train stress and allows the springs to perform more effectively at high engine speeds. Titanium is also very strong and resistant to wear, ensuring longevity in a high-stress environment.

When installing this kit, it's important to ensure your valve guides are in excellent condition and properly clearanced for your camshafts. Because this is a performance-oriented component, we recommend consulting the GSC Power Division installation instructions or a qualified engine builder to ensure proper setup and to achieve the best results for your specific build. This kit is a key component for anyone serious about maximizing the performance and reliability of their 4G63T engine.
