Using COMP Cams Shaft Mount Rocker Systems is one of the most effective ways to increase horsepower for your LS rectangle port cylinder heads. These rocker systems transfer power from the camshaft to the valve by properly positioning the rocker over the valve and keep the valve timing stable through out the rpm range. Rather than being mounted on a stud, a horizontal shaft works as the fulcrum, which significantly increases mounting stiffness and valve train stability. Constructed from high strength 2024 aluminum and using an 8620 hardened steel shaft, COMP® shaft rockers are designed using the latest in computer technology and are field tested by experts in every type of racing.

• Rigidity of the shaft system adds stability to the cylinder head and the valve train for high RPM
• Most efficient way to transfer the power of the camshaft to the valve
• Made from 2024 aluminum and mounted on an 8620 hardened steel shaft
• Designed using the latest in computer technology
