GSC Billet S3 Cams 280/280 4G63T (Mitsubishi Evo 4-8)

These cams are intended for the 800whp to take advantage of a very large turbo. these are NOT suggested for anyone running smaller than the 67mm to GT42R turbo.

These are GSC's new 7000 Series Full Billet Camshafts. These cams can handle a lot more abuse due to the strength of the forged steel while holding better tolerances with a better design. 

GSC Power-Division is very proud to announce the official release of the all new, 7000 Series Full Billet Camshaft Product Line. These new camshafts are 100% in-house cut and ground on the newest, most precise CNC machines available. At GSC, we believe that if you want something done right, and up to a higher level of standards; you have to do it yourself. The 7000 Series camshafts take the import valvetrain 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

These cams are intended for the 800whp+ goal to take advantage of a very large turbo. these are NOT suggested for anyone running smaller than the 67mm to GT42R turbo.


**If using aftermarket cam gears(especially AEM) check the bolt lenght, some cam gears are too thick for the OEM bolt on the Billet cams, a 40mm underhead length bolt may be necessary in this case**
