Die-Formed Steel Rocker Arms
Economically priced for replacement or budget engine rebuild. Stock design made of better, heat-treated material with long or extra long slots to provide more travel for increased valve lift and ball or sled fulcrum with a high amount of friction.

Nitro-Carb Steel Rocker Arms
For race use where rules require stock-type rockers, these offer 3 to 5 times greater resistance to wear, fatigue, and fracture in high-stress areas. Heat-treated nitro-carb steel rockers deliver the most accurate ratios of any comparable rocker. Most have extra long slots; all are complete with oil-groove pivot balls & adjusting nuts.
