35.5mm - Ultra Stainless Steel Valves

35.5mm - Ultra Stainless Steel Valves. SOLD EACH. The all new Ultra Series represents 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 end registers 556 on the Rockwell C scale, and eliminates the problem of valve stem flaring and premature damage.

You can now run Stainless Steel Valves with improved flow in every day highway use without the risk of valve stem failure due to soft stainless materials. Ultra Series 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.

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 Empi.
