Valve Spring Set, Dual, Road High Performance
160 lb at 400" for standard Cooper S or twin spring set ups. These are great springs for all standard uses but are improved and uprated over all original factory fitted springs. Special Swedish spring wire is used to produce a spring that will tolerate lift of up to .475", as is found with high-lift rockers. Suitable for up to 7000 rpm. Bottom collar springs are not required on these springs.
