This V2 version of our Stage 2 camshaft makes more power and torque everywhere in the curve compared to our legendary LS3 cams. Developed in house, we went back to the drawing board to find even more power and torque. These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.
