Champion Shaft Mounted 1.1:1 Rocker Arms GX390 Predator 420

Product Description

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

1.1:1 Ratio

Studs and Nuts Included
