S&S Cycle Rocker Box Center O-Ring for S&S Die-Cast Rocker Boxes 1984-2017

S&S Cycle Rocker Box Center O-Ring for S&S Die-Cast Rocker Boxes 1984-2017

Oil seeping past the rocker box center O-ring creates a slow drip at the base of the rocker box that migrates over time and becomes the source of that persistent wet spot below the engine. The S&S Cycle Rocker Box Center O-Ring provides the factory-correct seal for S&S die-cast rocker boxes, closing the center passage between the rocker box and cylinder head.
