All new cylindrical single valve spring kit for the Subaru turbo EJ series motors. Made for the Suby owner that daily drives their hot rod and keeps the boost and revs down. These Springs are the same quality and consistency as our popular beehive spring kit. The nano-peened AS50 round wire will perform with a RPM limit of 8200 and boost levels up to 32PSI on S1 or S2 profile cams. Strict quality control on the springs and the CNC machined Titanium retainers give you peace of mind that your valvetrain is always under control.

GSC Power-Division was started in 2004 when a need for high performance camshafts for Japanese turbo cars had little worth while offerings. Using cutting edge design software and quality chill cast and ductile iron billets ground on one of the most advanced CNC grinding equipment in the world has given GSC the chance to become a world wide supplier for some of the very best performance camshafts in our markets.
