The 5000 Series Valves have become the alternative for performance engine builders that use our competitors “street” or “performance valve€�. These valves are machined in our CNC centers allowing tight tolerances and cost effective design. They feature a one-piece forging made from stainless steel, a special heat treatment process, hard chrome stems, and hard tip. Most applications are available in an undercut stem and dished head, while other applications are available in straight stem and flat head. These valves provide our customers with maximum value for their dollar, and are designed for Street Performance engines, mildly modified Drag and Oval Track applications.

These valves are available for both the traditional Domestic performance and racing engine market and the Sport Compact performance and racing market.

Many of the 5000 series valves feature flat combustion chamber faces to help increase compression in naturally aspirated engines
