Engineered for high-performance Ford and Mazda Duratec applications, the Supertech SPRK-TS-DUR-DS single valve spring kit provides the necessary tension to maintain valvetrain stability at high RPM. By increasing seat pressure to 55 lbs at a 35.0mm install height, these springs effectively eliminate valve float, ensuring precise valve timing during aggressive camshaft operation or increased boost levels.

Each spring is manufactured from premium chrome silicon steel for exceptional fatigue resistance and long-term durability under extreme racing conditions. This kit is designed to replace factory components, offering a significant upgrade for street and track builds alike.
