Ultra Stainless Steel Valves represent the biggest advance in standard length Stainless Steel Valves for use in VW engines to become available to the engine builder. The Ultra Series features a one piece forged stem and valve head with a fused stellite valve stem end. The stellite stem tip registers 556 on the Rockwell C scale, and eliminates the problem of valve stem flaring and premature damage.

You can now run Ultra Stainless Steel Valves with improved flow in every day highway use without the risk of valve stem failure due to soft stainless materials. Ultra Stainless Steel Valves are manufactured with a thin head and swirl polished in a counter rotational pattern for increased flow. The valve stems are polished to decrease friction and temperature. A new heat treating process is used to increase the hardness of the 214NSS stainless material to over 20% of normal stainless steel valves. You can use standard VW keepers with steel, aluminum, chromoly or titanium retainers.

Stainless Steel Ultra Valves are standard length (112mm), and can be used for either Intake or Exhaust. You can choose from all popular sizes to fit VW Heads or request Stainless Steel Ultra Valves in some models of Cylinder Heads supplied by CB Performance!
