The 4Piston Valve Spring Micrometer is used between the seat base in the head and the retainer to get a quick and accurate measurement of your valve spring installed height. This tool is sized so that it can be used in a variety of applications including the tight constraints of Honda B, H, and K series engines, as well as most overhead cam engines. These high quality tools have a fine thread pitch for great accuracy and are easy to use with convenient gripping surfaces.
