Champion Shaft Mounted Rocker Arms for Honda GX200, 6.5 OHV Clones, 212 Predator - Original (X) Style
These are the famous "Champion" heavy duty 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-to-side. Further, they have considerably more rigidity than stud rockers, so they rarely need adjustment once set.
- Fits Honda GX200/clones, Ducar, Tillotson, 212cc Non-Hemi Predator Engines, and other Non-Hemi OHV Engines.
- Studs and nuts included (Studs may require tools to install - too tight to turn by hand.)
*Updated Ratio Information*
The Champion rockers have long been advertised as 1:1 ratio. More recently, testing shows the original "X" style rockers are actually closer to 1.05:1, while the "New" style Champion rockers are closer to 1.1:1 ratio. We have also tested other brand's castings of the original "X" style Champion rockers who are claiming to have "1.0:1" ratio, and have found similar, higher ratio results. Do not expect to have a true 1:1 ratio from any brand advertising this.

*Note: Does not fit hemi style cylinder heads.
As with any other aftermarket part, additional modifications may be necessary to fully utilize this component (e.g. longer pushrods, clearance of valve cover). Do not assume this is a drop-in part or that you don't have to check for fit or proper operation.
Champion suggests using oil and tools to install, rather than tightening by hand.
