Stud Mount Valve Spring Compressor Conversion Kit. Contains all pars necessary to convert Part No. 62370 to fit Jesel Rocker Shaft Valve Springs

• Between-rounds valve spring changing is greatly simplified with this tool
• Unlike models offered by other manufacturers, Moroso's stud mount tool fits both 3/8" and 7/16" rocker studs and is much stronger in the handle area to withstand the pressures of today's "extreme high pressure" valve springs
• The 12in handle gives all the leverage needed to compress the strongest springs
