The Supertech SPRK-M1007D dual valve spring kit is engineered for high-performance Mitsubishi 4G63 engines that require increased seat pressure and lift capacity. This kit is a critical valvetrain upgrade for builds featuring aggressive aftermarket camshafts and high-boost configurations where valve float can compromise engine safety and power delivery.

By utilizing a dual-spring design, Supertech provides a higher spring rate and improved harmonic damping compared to factory single-spring setups. This ensures precise valve control at high RPM, allowing for a safer redline and consistent performance under extreme racing conditions. These springs are manufactured from high-quality chrome silicon vanadium steel alloy for maximum durability and fatigue resistance.

  • Engineered for the Mitsubishi 4G63 valvetrain
  • Dual spring configuration for superior high-RPM stability
  • Prevents valve float in high-lift and high-boost applications
  • Manufactured from high-tensile chrome silicon vanadium steel
  • Manufacturer Part Number: SPRK-M1007D
