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.
This spring kits contain steel retainers. Kits come complete with sixteen valve springs, retainers, lower
spring seats, machined steel valve locks and Viton˝ oil seals.
