Single Valve Springs & Titanium Retainers
Supertech Performance Single Valve Springs are made with premium Super Clean Chrome Silicon Vanadium Steel alloy for higher performance and durability at high rpms and better memory. Computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions. Computer software also allows us to make sure that the harmonics are well under control.
Titanium Retainers are manufactured with high quality military certified Titanium alloy, CNC machined for tight that will ensure long term durability.
Black Nitride Valves
- The micro hardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitride 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 nitride 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 nitride 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.
Bronze Valve Guides
The Supertech Valve Guides are precision-machined from high quality Manganese Bronze material. These guides in combination wtih our low friction black nitride valves provides the best solution for performance and durability.
Interference fit in the cylinder head should be about 0.04mm (0.0015").  Inner bore needs to be honed after installation
