Summit Racing™ Pro LS Vortec Truck Swap Camshafts

Summit Racing™ Pro LS Truck Swap cams are affordable and give you maximum punch where the torque converter hits. The cam lobes are designed for excellent valvetrain longevity. Both drop-in or high-lift versions are available. They come in stages allowing you to quickly determine which gives you the idle and efficiency you are looking for. Idle response and the midrange torque from theses camshafts is unmatched. Starting with American bearing steel, they are precision machined on a Landis 3LB CNC grinder with CBN diamond wheels for an extremely good finish quality. The lobes have been designed for stability at high rpm with the spring pressures found in commonly available, quality spring packs.
