"Champion" HD Shaft Rockers for GX390 / GX420 / GX440/ 460cc Clones
These are the famous "Champion" HD Shaft Rockers! They are arguably the best bang for your buck when it comes to valvetrain stability.
A Shaft-Rocker eliminates the need for a guideplate 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.
