Eng Rocker Arm Shaft

Using COMP Shaft Mount Rocker Systems is one of the most effective ways to increase horsepower. These systems transfer power from the Camshaft to the valve by properly positioning the Rocker over the valve. 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

Product Overview

Using COMP Shaft Mount Rocker Systems is one of the most effective ways to increase horsepower. These systems transfer the power of the camshaft to the valve by properly positioning the rocker over the valve. Constructed from 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.
• Made from 2024 aluminum and use 8620 hardened steel shaft
• Most efficient way to transfer the power of the cam to the valve
• Rigidity of the shaft system adds stability to the cylinder head and the valve train
• Use an oiling system that ensures consistent oil flow from the pushrod cup to the shaft bearings and then on to the roller tip

Rocker Arms, Shaft Mount, Full Roller, Aluminum, Natural, 1.5 Ratio, for Use with Edelbrock Cylinder Heads, Pontiac, Pontiac V8, Kit

COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.
