Part #: CHAMP390

Description -
Shaft Mounted 1.1:1 Ratio Rocker Arms for GX390, 420 OHV, and 460cc
  • These are the famous "Champion" HD shaft rockers for GX390 and 420 OHV engines. 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 to side. Further, they have considerably more rigidity than stud rockers, so they rarely need adjustment once set.
  • Studs and nuts included (Studs may require tools to install - too tight to turn by hand.)
  • Fits GX390 and 420 OHV engines. Will not fit GX270s.

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 (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.

Rockers are designed as 1.1 to 1, but due to manufacuring and stamping tolerenace, they may vary some.

Does not fit hemi style cylinder heads. Verify that you do not have a hemi head before purchasing as we do not allow returns on this item.*
