GSC P-D Nissan VR38DETT Conical Valve Spring Kit w/ TVS1903 Conical Spring

The GSC Power-Division Conical Valve Spring Kit with Ti Retainer for the Nissan VR38DET provides superior valvetrain harmonic stability compared to traditional cylindrical or beehive springs. Its varying coil diameter and spacing act as a natural harmonic damper, reducing stress and wear for longer component life, especially in high-performance engines. Each spring undergoes a super-finished surface treatment and a patented, multi-step heat treatment process, resulting in a reliable, high-performance product that supports higher RPMs, more aggressive cam profiles, and increased boost pressures.
