Higher Flow Rates
Supertech Valves are not finished from generic blanks, they are specifically designed for each and every application. Supertech works relentlessly, testing and researching every aspect trying to improve the air flow of the valve design.

With every valve design Supertech strives to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc.

Stem Super finishing
In 2006 Supertech introduced stem Superfinishing as a standard addition to all of the valves and provided it at no additional cost. When our Superfinish is combined with a Black Nitrided valve it reduces the surface roughness to 1/3 of the chrome coated valve. The end result… unsurpassed performance and durability.

Strict Dimensional Tolerances
It's unlikely you will find any of Supertech's competitor’s valves with stricter dimensional tolerances than theirs. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere!

Black Nitrade:
This is a hardening treatment that even though it is not widely used as the chrome coating, it has several benefits and is becoming very popular, mainly for European and Japanese applications.
The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum).
Surface finish is smoother than with chromed stems, having less friction between stem and guide.
Valve seat surface is harder with the nitrided 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's 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 nitrided layer is adhered to the base material at a microscopic level, so does not flake or break 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 and a hardened tip.
