GSC Power-Division Single Valve Spring and Titanium Retainer Kit for Subaru EJ

The GSC Power-Division Single Cylindrical Valve Spring with Ti Retainer for the Subaru EJ platforms includes 16 titanium retainers and 16 cylindrical valve springs. These round wire springs still have the same high quality attention to detail as our popular beehive kits. The GSC5743 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.
