This rocker shaft support ring supports the rocker shaft in the cylinder head of a classic Citroën engine. The ring distributes the load over the mounting surface and helps keep the shaft in position. The part contributes to stable guidance of the rockers and thus to uniform valve operation. The ring is suitable for use in the 11CV and 11D engine configuration. The design matches the existing mounting points and dimensions in the head. The support ring functions together with other valve train and camshaft components in the upper engine assembly.
