Supergrip Single Groove Valve (specify Size)
Aircooled VW Single Groove Valves Supergrip
The Supergrip Valve series should be your only choice of valves when quality and performance are your number one concern in valve selection and components.
These are the same Valves used in the 044; Cylinder Heads! Adapted by the same design used in NASCAR Racing and applied the VW Cylinder Head. One of the major design imperfections of standard VW valves, is the design of the locking grooves on the stem, which is prone to fast erosion and even valve stem breakage when used in a performance environment.
Supergrip Valves are machined from 21-4N Stainless Steel w/Stellite Tips and use only a single groove for retaining the valve. Each valve stem is then hard chrome plated for a long, durable, wear resistent surface. Machined keepers clasp the valve stem, not the groove, which leads to erosion of the valve keeper groove area.
You can now be more confident than ever when selecting valves for a performance application when you decide to run the tried and true design of 7 degree single groove valves. These Valves require the use of SUPERGRIP™ Chromoly Retainers, and Single Groove Valve Locks.
