Shaft Mount

Made from 2024 aluminum and utilize an 8620 hardened steel shaft
Most efficient way to transfer the power from the camshaft to the valve
Rigidity of the shaft system adds stability to both the cylinder head and the valve train
Oiling system ensures consistent oil flow from the pushrod cup to the shaft bearings and then on to the roller tip

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.

COMP Cams® Shaft Mount Rockers

Aluminum

Constructed from an aluminum alloy with tensile strength of 80,000 psi
Needle bearing trunions allow spring pressures of 350 lbs. open pressure
Perfect for any performance street application

Unlike stud mounted rockers, COMP® Aluminum Shaft Mount Rocker Systems utilize a hardened steel horizontal shaft as the fulcrum, which significantly increases mounting stiffness and valve train stability. These systems transfer power from the camshaft to the valve by properly positioning the rocker over the value.

Constructed from a high strength aluminum alloy and utilizing needle bearing trunions, COMP® shaft rockers are designed using the latest in computer technology and are field tested by experts in every type of racing.
