Description
Supertech stainless steel intake valves are manufactured from an enhanced version of EV8 (21-4N) steel. We have chosen this material specifically because it’s the highest grade of steel available and provides the strength to withstand just about any application. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for even greater strength at higher temperatures. Our stainless steel valves are one piece forged valves, and depending on the application feature hardened tips, hardened seats, swirl polish and undercut.
This listing is for complete sets of valves. Single groove keepers are supplied with single groove valves.
