GSC Power Division billet S2 camshafts for Mitsubishi Evolution 4–8 use a 4G63 profile (274/274) in billet construction to provide a durable, repeatable cam option for performance builds. These cams are intended to alter valve timing and lift characteristics according to the S2 spec, supporting tuned engines that require stronger cam components and consistent manufacturing tolerances for reliable valvetrain behavior.
