ScienceofSpeed Valve Springs, Retainers, & Bases

ScienceofSpeed offers replacement spring, retainers, and bases for competition use or for use with increased lift camshafts. The three following components must be used together as a set.

Valve Springs: Performance valve springs allow increased lift while preventing valve float. Dual spring design includes inner and outer springs. Manufactured from Super-clean Silicon Vanadium Steel alloy - excellent consistency through heat and compression cycles. Seat pressure increased by approximately 20% increases valve action performance while not putting unnecessary stress on rocker/camshaft. Includes 48 pieces for intake and exhaust valves.
