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.
