This camshaft is designed specifically for race and high-performance applications, offering a .450 lift on both intake and exhaust, paired with extended duration to support increased airflow and higher RPM potential. It’s not meant for mild street trucks or stock daily drivers—this is for the builder who’s already deep into fueling, turbo, and supporting mods, and who’s looking for more top-end power and improved throttle response under load. Built for Power and Precision Along with the camshaft, this kit includes the necessary key to ensure secure and precise installation. Industrial Injection strongly recommends checking piston-to-valve clearance before installation, with at least .080 inch on the intake and .120 inch on the exhaust to maintain safe operating margins. That kind of attention to detail is what separates a solid performance build from an expensive failure. Whether you're dialing in a competition truck or pushing the limits at the track, this Stage 2 cam is built to help your Duramax breathe better, rev harder, and put more power to the ground when it counts. For the right build, this camshaft is a game changer.
