GSC Power Division GSC Valve Spring Kit | Subaru EJ (5073) GSC Power-Division

Conical Valve Spring Titanium Retainer & Spring Seat Kit by GSC Power-Division

The GSC Power-Division High Pressure Conical Valve Spring with Ti Retainer for Subaru Turbo

EJ Platforms includes 16 titanium retainers, 16 conical valve springs, and 16 chromoly valve spring seats.

High RPM and High Boost levels are not a problem on these kits. 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.
