Valve Stems

Valve Stems & Performance Valve Stems

Valve stems are the shafts of the intake and exhaust valves that ride inside the valve guides and are actuated by the camshaft through the rocker arms or cam followers. Upgraded stainless steel or inconel valve stems offer improved heat resistance and strength for high-performance and forced-induction applications.

OneFastShop carries valve stems including stainless steel intake and exhaust valves, inconel exhaust valves, oversized and undersized stem replacements, and application-specific valve sets for popular performance engine platforms.

Every valve stem at OneFastShop ships brand-new with manufacturer warranty coverage. Whether you're replacing worn valves during a head rebuild, upgrading to stainless or inconel for a performance build, or sourcing valves for a fresh set of heads, OneFastShop has the valves.
