GSC Power-Division Single Cylindrical Valve Spring Kit with Ti Retainer for the 2JZ & 1JZ includes 24 titanium retainers and 24 cylindrical valve springs. This is a great spring kit for the daily driver with an S1 or S2 cam profile that keeps the boost and revs below 32 psi and 8500 RPM. These round wire springs still have the same high quality attention to detail as our popular beehive kits. The GSC5744 is Nano-peened and batched according to seat pressure within our specs. The lightweight titanium retainers are CNC machined with tolerances and repeatability that are unmatched by other brands. This keeps a consistent seat pressure across the head for ultimate reliability and performance.
