Product Details

This Supertech single valve spring kit for Ford and Mazda Duratec engines includes all the necessary components to upgrade your valve springs. You'll get a set of single valve springs, designed to provide 55lbs of pressure at 35mm installed height. These springs are a popular choice for builders looking to handle more aggressive camshaft profiles or higher RPM limits than stock springs can safely manage.

Supertech is known for making well-built valvetrain components, and these springs are no exception. They are constructed from high-strength spring steel, ensuring they can withstand the repeated stress of opening and closing valves at high engine speeds. The single spring design is straightforward, making it a solid option for many performance builds where extreme lift or dual spring setups aren't required. When installing these, pay close attention to the manufacturer's recommended installed height to ensure you achieve the correct seat pressure, which is crucial for proper valve control and engine performance.

If you're rebuilding the top end of your Duratec engine for a performance application, these springs are a critical component. They work in conjunction with your camshafts and retainers to control valve motion accurately. Make sure you have the correct retainers and valve seals to go with them, as these are typically sold separately. Proper installation is key to unlocking the full potential and reliability of this upgrade.
