Ensure valvetrain stability at high RPMs with the Supertech Dual Valve Spring Kit for Ford Duratec and Mazda MZR engines. Designed to support aggressive camshaft profiles and forced induction setups, this kit provides the necessary seat pressure to prevent valve float and maintain precise engine timing during high-performance use.

Engineered for the 2.0L, 2.3L, and 2.5L powerplants, these dual springs offer superior harmonic dampening compared to single-spring configurations. By utilizing a dual-coil architecture, this kit provides an added layer of safety; the secondary spring helps prevent the valve from dropping into the combustion chamber in the event of a primary spring failure.

  • Compatible with Ford Duratec and Mazda MZR 2.0L, 2.3L, and 2.5L engines
  • Designed for high-lift camshafts and increased redline applications
  • Reduces harmonic resonance and improves valvetrain durability
  • Manufacturer Part Number: SPRK-TS-DUR-D1
