GSC P-D Nissan VR38DETT High Pressure Conical Valve Spring Kit w/ Titanium Retainer

The 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. Conical valve springs offer superior valvetrain harmonic stability compared to cylindrical or beehive springs due to their varying coil diameter and spacing, acting as a natural harmonic damper. This reduces stress and wear, extending component life, which is crucial for engines with aftermarket modifications. Each GSC conical spring features a super finished surface treatment and a patented, multi-step heat treatment process, resulting in a reliable, high-performance spring that supports higher RPMs, more aggressive cam profiles, and increased boost pressures.
