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 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.

• These are the older "forged" version which are known to be considerably stronger than the newer & cheaper "stamped" version.
• Studs & Nuts Included

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.
