Details: 

GSC 7000 Series Full Billet Camshafts are 100% in-house cut and ground on the newest, most precise CNC machines available.  The 7000 Series camshafts take the import valve train market to another level, being the only readily available and affordable billet camshafts for sport compact/ import performance cars.  

The lobe profiles are still the same spec GSC Power-Division is known for worldwide, giving the best power gains and smoothest drivability out of anyone in the industry.  Appearance wise the new dark nitride coating aids in wear/fatigue resistance, lubricity, and superior corrosion resistance. The 7000 Series camshafts have raised the bar and will be the cams that all others will be judged against.
