Every cylinder head assembled by Thunder Racing utilizes our Power Technology PT-200 valve spring tester to ensure accurate and consistent valve spring setup. This spring tester is used by many of the leading camshaft companies in testing their different spring packages. We verify installed height, seat pressure, open pressure, coil bind height, and spring rate and can provide each customer with a printout outlining each of these parameters for their specific cylinder heads.
