The GSC Power-Division High Pressure Conical Valve Spring
Kit with Ti Retainer for the Toyota 2JZ & 1JZ includes 24 titanium
retainers and 24 conical valve springs. True conical valve springs are not a
new concept and are industry proven to provide several key advantages over
traditional spring designs. A major advantage of conical springs vs.
traditional cylindrical or beehive springs is the damping and removal of
valvetrain harmonics. Of the three designs, conical springs are the front
runners in valvetrain harmonic stability. Utilizing a varying coil diameter as
well as coil spacing, a conical spring acts as a natural harmonic damper in the
transfer of valvetrain shock. This translates to less stress, less wear, and a
longer life of the included components. This level of protection is needed in
today’s engines being pushed to their physical and mechanical limits by
aftermarket modifications. Every GSC conical spring offers a super finished
surface treatment to go along with the patented, multi-step heat treatment
process. The finished product is an extremely reliable, high-performance spring
allowing the users to push higher RPMs, use more aggressive cam profiles, and
turn up higher boost pressures.
