Using the new COMP Cams® Off-Set 1.7 Shaft Rockers for GM LS3/L92 is one of the most effective ways to increase horsepower. The rigidity of the shaft system adds stability to the cylinder head and valve train alike. It is the most efficient way to transfer the power of the camshaft to the valve by properly positioning the rocker over the valve. They are constructed from 2024 aluminum and use an 8620 hardened steel shaft. These shaft rockers feature an oiling system designed to deliver consistent oil flow from the pushrod cup to the shaft bearings and on to the roller tip.
