Adding Bronze Bushings to Ductile Iron Rockers

RAS installs bushings in the rockers using the original bore and adds smaller diameter shafts with thicker walls. I believe they correct the individual ratios in the process and include new 12 point adjusters and hold-downs in their package deal. Bushings are drilled and/or blocked in the rocker as needed for better oiling. OEM 273, Crane, Isky, etc.
