GSC Power Division 4B11T Valvetrain Upgrade

Take your Mitsubishi 4B11T engine to the next level with the GSC Power Division High Pressure Single Conical Valve Spring and Titanium Retainer Kit. Specifically developed for the Evolution X platform, this kit is designed to handle the extreme pressures and high RPMs associated with high-horsepower turbo builds.

Key Features

• High Pressure Springs: Conical design provides increased seat pressure to prevent valve float under high boost conditions.
• Titanium Retainers: Lightweight construction minimizes valvetrain mass for improved engine response and durability.
• Precision Fitment: Engineered specifically for the 4B11T cylinder head for a perfect, hassle-free installation.
• Boost-Ready: Designed to maintain valve control even when running aggressive boost levels and high-lift camshafts.

When you increase the boost on your 4B11T, the stock valve springs often become the weak link, leading to valve float and potential engine damage. The GSC High Pressure kit eliminates this risk, providing the stability and control your engine needs to make consistent power. The conical spring design offers progressive rate benefits, ensuring that your valvetrain remains stable throughout the entire RPM range. Whether you are drag racing, road racing, or building a high-performance street car, this kit is an essential component for reliability.
