Brand new: The racer's choice for exceptionally long spring life and resistance to breakage and fatigue is the H-11 Valve Spring. Designed for high lift race cams, long duration, 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. Technical Details: 1.260" Outside Diameter, 120 lbs Seat Pressure @ 1.750” Installed Height, 350 lbs Open Pressure @ 1.250”, 1.100” Coil Bind. Max lift .650" minus required clearance. Direct Import Cost: $299.80, Sell for $229
Lunati Springs They are designed for straight fit into the GenIII motors, ie: LS1, LS2 etc. But there is no reason why they cannot fit-up into other heads, taking into consideration their specs. Cheers, Mark
