    Supertech uses their 20+ years of experience in the manufacturing of racing valves along with the application of computerized Finite Element Analysis (FEA).  Intensive testing as well as working very closely with many engine builders in order to continuously improve and provide the market with the best possible product for every application. High flow rates, durability and quality are of great concern.

    Only the best materials are used in the creation of Supertech Performance's valves. 

    Ready to handle whatever abuse you can throw at them. 

    Perfect for forced induction applications and high revving naturally aspirated applications.

    • Benefits for Black Nitride Coating includes:

      - The micro hardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrated layer (micro hardness is 800hv minimum)
      - Surface finish is smoother than with chromed valve stems, having less friction between the stem and guide.
      - Valve seat surface is harder with the nitrated layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
      - Higher RPM engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
      - The nitrated layer is adhered to the base material at microscopic level, so it will not "flake" or brake when the valves bend due to impacts with the pistons.
      - The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.
      - All valves are swirl polished, have stem undercut, a hardened tip, and more.
