Speedmaster®
8mm LS Steel & Viton Dual/Single Spring Valve Stem Seals (Suits: 0.500" Guides)
Overview
Valve stem seals control the lubrication of the valve stem as it slides in the valve guide. Too little oil causes stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and early valve grind. Speedmaster valve seals are posi-stop seals made from high-temperature Viton material for a long-lasting seal.
