The GSC Power-Division Single Cylindrical Valve Spring Kit with Ti Retainers for the Subaru 2015+WRX, BRZ, Scion FRS and Toyota FT86 using the new 2.0L NA boxer engine includes 16 titanium retainers, 16 cylindrical valve springs, and 16 spring seats. These round wire springs still have the same high quality attention to detail as our popular beehive kits. The GSC5756 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.
