ABSTRACT:
This roller rocker is designed to change the valve lifter rocker arm leverage of an engine to increase the engine's performance. Primarily, it consists of a sliding pushrod seat, and a threaded Allen bolt is threaded into an opening in the sliding pushrod seat for traversing the seat in an opening in the body of the rocker arm. The design also includes a locking ring to retain the bolt, and an Allen set screw is received in the arm to lock the Allen bolt in its setting.
