Crane Cams now offers new "dual spring" high performance valve spring kits for the LS Series of engines designed to meet increased valve lift requirements. Precision designed and tested for today's modern camshaft lobes with increased lobe lift. Using high tensile chromium silicon vanadium alloy material, the springs are suitable for both 1.70:1 and 1.80:1 rocker arms with valve lifts up to .660".These newly designed springs have been extensively tested in LS engines on our in-house Spintron machines for many millions of cycles, with hydraulic and mechanical roller lifter Cams - and showed significant improvments in fatigue life and load loss over competitive springs.
