Make me an offer.SOLD VALVE SPRING SETS H-11 Steel Dual Spring Sets The racer’s choice for exceptionally long spring life and resistance to breakage and fatigue is the H-11Valve Spring. Designed for high lift race cams, the Lunati H-11 valve springs have 5 times more chrome in the material than Chrome Silicon valve springs, plus nickel, molybdenum and vanadium, metals that make stronger and more resistant to the effects of engine temperature and fatigue. Chrome Silicon makes an excellent valve spring for normal high performance applications, but in high stress race applications, H-11 represents a far better alternative than Chrome Silicon.
