Champion Shaft Mounted 1.1:1 Rocker Arms GX390 Predator 420
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 rigidity than stud rockers so they rarely need adjustment once set.
Fits Honda GX390, Predator 420 Non-Hemi, and other 13-16HP clone engines with non-Hemi type cylinder heads
