Ferrea engineers high-quality automotive parts and accessories trusted by enthusiasts and shops across North America. At GGCRACING we stock the full Ferrea lineup with fast shipping and expert fitment support — order with confidence.
The Mitsubishi 4G63 and 4G63T engines are known for their high-output potential, but they also place heavy demands on the cylinder head components. The Ferrea 6.55mm Viton Hi-Temp Exhaust Valve Stem Seal kit is designed to handle the extreme heat generated by the exhaust valves in these turbocharged powerplants. Unlike standard rubber seals that can harden and fail under intense heat, Ferrea’s Viton material remains supple and provides a consistent, leak-free seal for the life of your engine build.
A cylinder head rebuild is incomplete without fresh valve seals. As the 4G63 is often subjected to aggressive tuning and high boost pressures, ensuring your valve stem seals are up to the task is a critical step in engine longevity. Ferrea is a trusted name in the racing industry, and these seals offer the peace of mind that your valvetrain is protected against oil contamination. Whether you are building a street-strip monster or a dedicated track car, these seals are an essential upgrade. Find all your performance engine components at GGCRACING.
