Supertech High Performance Valve Springs

Precision Control. Proven Performance.

Supertech valve springs are engineered for maximum valvetrain stability and high-RPM reliability. Using Superclean Chrome Silicon Vanadium alloy, every spring is computer-designed to ensure optimal wire stress and harmonic balance. These advanced materials and processes deliver unmatched fatigue resistance and consistent seat pressure under the most demanding conditions..

 

Performance-Driven Engineering

  • High-tensile Chrome Silicon Vanadium construction for extreme strength and fatigue life.
  • Computer-modeled coil design to optimize harmonic control and spring pressure.
  • Gas nitriding and shot-peening process enhances surface hardness and durability.
  • Dual and beehive configurations to suit different performance needs.
  • Tested to exceed OEM stress limits for maximum reliability under race conditions.

 

High Performance Valve Springs

Race-proven Dual, Single, Conical and Beehive valve springs built from premium Chrome Silicon Vanadium alloy for unmatched fatigue strength and harmonic control. Titanium retainers included on select kits. Safe up to 9000 RPM.

 

Popular Applications

Available for popular performance engines including Honda K-Series, Toyota 2JZ & 4AGE, BMW S54/S55, Nissan SR20, Acura K24, Subaru EJ25, Mini R56 N14/N18, and more.
