These high quality rocker arms and shafts are the same as we use in the KN-Series engines, and fit stock knuckle engines too. Stock 1:1 rocker ratio. Rocker arms are sold individually and as sets of four rocker arms and shafts. Rocker arms include rocker shafts, since rocker arms are not compatible with stock rocker shafts. All four rocker arms and shafts are unique.
Rocker shafts are available as a set of four only. Flathead Power® rocker shafts are designed to fit stock or Flathead Power rocker arm covers (tins), and include washers and spacers.
Fits 1940–'48 OHV big twins, compatible with S&S or Stock tins, not compatible with stock rocker shafts.
