"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.

Studs & Nuts Included

**WARNING: These rockers are NOT a Set-and-Forget upgrade, they require some knowledge of engines and valvetrain geometry to work properly. We cannot provide installation support due to the immense amount of variables between different makes of engines!***

As with any other aftermarket part, additional modifications may be necessary to fully utilize this component. (Ex: longer pushrods, clearancing of valve cover). Do not assume this is a drop in part or that you don’t have to check for fitment and proper operation.
