The GSC5079 kit is designed to work with the OEM spring seat or GSC1004. Able to use NEW OEM valve spring keepers or our GSC1003 keeper kit. No need for special aftermarket locks that have the potential of being the wrong angle. Conical springs allow for the use of a smaller, lighter retainer and have a varying spring rate allowing for higher RPM and more valve control.  GSC Power Division Pressure Conical Spring

• Max RPM: 10,500 RPM
• Max boost: 50 psi

GSC Power-Division Conical Valve Spring Kit with Ti Retainer for the Nissan VR38DET includes 24 titanium retainers, 24 conical valve springs, and 24 valve spring shims. 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.

• Max RPM:  10,000 RPM
• Max boost: 40+ psi
• 1,500+ HP
