NotesSelecting correct push rod length is vital in obtaining the proper geometry for valve train. The rocker should ride in the center of valve stem so it does not come off of stem as cam opens and closes. Push rod length will raise or lower rocker moving where it sits on valve stem. Camshaft, lifters, rockers and valves all play a part in determining what length of push rod is required. We offer a couple of tools to help check this length. Part number 50542137 and 28799720 will help with finding correct push rod length.
