Supertech Dual Valve Springs
Supertech performance valve springs are made with premium Superclean Chrome Silicon Vanadium Steel Alloy for higher performance and durability. Computer designed to ensure that wire stress levels do not overpass the limits for long durability under extreme conditions and harmonics are well under control.
