ScienceofSpeed offers replacement spring, retainers, and bases for
competition use or for use with increased lift camshafts. The three
following componentsmust 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.
