Replacement 4340 Super Heavy Duty Rocker Shafts (pair) - New

Super heavy duty .165" wall thickness rocker shafts that are INCLUDED with (and developed specifically for) our roller rocker arms. Thinwall, light duty rocker shafts supplied with "the competitions" roller rocker sets are shown on the left for comparison. In addition to the much heavier wall thickness, our HD shafts are made from solid 4340 steel. This helps the shafts to maintain perfect roundness under extreme loads, and allows the holddowns to be tightened to the proper torque without distorting or "ovaling," which is a common problem with the thinner shafts. We sell these heavy duty shafts separately as a service replacement part for our roller rockers. Diameter is the same as a standard factory shaft, however due to the position of the oiling holes, these WILL NOT work with factory stamped rocker arms. One package includes TWO shafts.
