Comp Cams Dual Valve Springs for GM LS7, LT1, LT4
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.
These new valve springs are optimized to improve performance in engines with taller installed heights. Capable of sustaining up to .700” valve lift from both hydraulic roller and solid roller camshafts, this 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.
Manufactured with a proprietary Super Finish that delivers superior strength, durability and valve train stability, Comp Cams .700″ Max Lift dual valve springs for GM LS7, LT1 and LT4 engines can handle extreme stress in high lift applications. They are suitable for both street and race applications.
