Rocker Arms, Shaft Mounted (Champion), GX390, GX420, & 460cc , 1.1 to 1

These are the famous "Champion" HD Shaft Rockers! They are arguably the best bang for your buck when it comes to valve train stability.

A Shaft-Rocker eliminates the need for a guide plate and prevents the rocker arms from walking side-side. Furthermore, they have considerably more ridgidity than stud rockers so they rarely need adjustment once set.
