These rockers are similar in design to the ones originally used on most engines, but incorporate features and improvements which make them a useful upgrade for a budget conscious engine builder. Careful attention to detail in manufacturing insures accurate ratios. Hardend steel alloys deliver long life at the fulcrum, valve and pushrod seat areas. Longer stud slot allow these rockers to work with higher lift cams.
