The GPI STG2 Low Lift Camshaft delivers a major performance jump for 2014+ 5.3L Direct Injected trucks (L83 / L84) without sacrificing drivability. Designed for enthusiasts who want sharper acceleration, stronger mid-range power, and a noticeable top-end bump, the STG2 is the ideal upgrade for street/strip builds running a 3000+ RPM converter.
