The GSC Power-Division Conical Valve Spring Kit with Titanium Retainer for the Nissan VR38DET comes complete with 24 titanium retainers, 24 conical valve springs, and 24 valve spring seats. Conical valve springs, although not a new concept, have proven themselves in the industry, offering several key advantages over traditional spring designs.
One of the primary benefits of conical springs compared to cylindrical or beehive springs is their superior ability to dampen and eliminate valvetrain harmonics. Among these designs, conical springs stand out as frontrunners in ensuring valvetrain harmonic stability. By incorporating varying coil diameters and spacing, conical springs naturally act as harmonic dampers, effectively reducing valvetrain shock. This results in decreased stress, minimized wear, and prolonged lifespan of the included components, a crucial level of protection for modern engines pushed to their physical and mechanical limits by aftermarket modifications.
Each GSC conical spring undergoes a meticulous process, featuring a super-finished surface treatment in addition to a patented, multi-step heat treatment. The result is an exceptionally reliable, high-performance spring that enables users to push higher RPMs, utilize more aggressive cam profiles, and increase boost pressures with confidence.
