COMP Cams 511-16 - Valve Seal Viton GM LS1 .313

Valve Stem Seal - Positive Stop - 8 mm Valve Stem - 0.494 in Guide - Steel Jacket / Viton - GM LS-Series - Set of 16

Providing the best sealing properties and spring clearance, viton valve seals are an excellent choice in performance applications. The 511 seals have a .600" OD and fit LS applications with 8mm valves and .500" OD guides.

COMP Cams offers a complete line of valve stem Seals, from the stock GM "O-Ring" to the positive-stop PTFE Seal. These Seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The "O-Ring" Seals use the standard retainer and oil splash shield. The umbrella Seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop PTFE Seal is used. We also have a smaller diameter Viton Seal available for triple spring Applications.
