ROCKER ARM COMPONENTS

We manufacture trunnion upgrade kits for both LS engines  and Cummins 24 valve engines.  In addition, we produce and stock a variety of rocker arm adjusting screws and jam nuts. We offer various diameters, lengths and radii in both ball style and cup style with and without oil holes. Our standard screws are made from 86L20 material and we also produce and stock a lesser variety in tool steel material for more extreme applications.  To inquire about our tool steel options, please contact us.
