COMP Cams introduces a new .700" Max Lift Dual Valve Spring that uses the additional installed height available in newer stock GM LS7, LT1 and LT4 engines to increase valve lift capacity and improve valve control. Capable of sustaining up to .700" valve lift from both hydraulic roller and solid roller camshafts, this new dual spring is also appropriate for use on milder applications when set up to be within .050" to .080" from coil bind at max valve lift. Our Super Finish processing enhances strength, durability and valve spring stability in extreme use. Designed for street/strip hydraulic and solid roller cams.
