New and Improved 1.2 Ratio Roller Tip Rockers for the Clone and Honda GX160/200 or Predator 212 NON Hemi. WILL NOT work on Hemi Predator!
Precision machined from chromoly steel with hardened roller tips and shafts. Dyno tested to 10000rpms with significant horsepower gains. Use stock rocker stud and pivot nut. Requires the use of GXC-412-00 ratio guide plate. Fits under stock valve cover. Shorter push rod length(5.160") and HP lash caps may be required depending on cam choice and cylinder head/block milling.

Installed the rocker arms with the appropriate pushrods and guide plate on a DJ-1116 hi compression head. worked like a charm. Good increase in power.
