Billet S2 Camshaft Kit

The GSC Power-Division Billet S2 Camshaft Kits (part number 7008S2) are precision-engineered camshafts designed for the Mitsubishi Lancer Evo 4-8. These S2 profile cams are crafted from billet material for superior strength and longevity, promising trouble-free, consistent performance. Manufactured 100% in the USA, they are built to meet or exceed demanding quality standards. These camshafts are ideal for builds targeting 400-700 WHP, offering significant gains of 50-70 WHP over stock, even with larger turbos, without sacrificing low-end power. They support a wide operating range from 4000-9000 RPMs for 2.0L engines or 3000-8000 RPMs for 2.2L+ engines, and can be used with the factory ECU via custom flashing. Installation requires upgraded valve springs, such as the GSC beehive valve spring replacement or full beehive valve spring kit with a titanium retainer. Additionally, Evo 4-7 models must use an Evo 8 trigger bolt for proper fitment. If using aftermarket cam gears, particularly AEM, verify bolt length as a 40mm underhead length bolt may be necessary to accommodate the billet cams.
