PowerMax cams for balanced intake and exhaust flow.

Crane PowerMax camshafts have lobe patterns designed to balance intake and exhaust flow. Their unique profiles produce maximum low, mid, and upper rpm power. Many PowerMax cams are designed to maximize the effects of nitrous oxide, supercharger, and turbocharger systems. They're available in both hydraulic and mechanical lift versions.
