Abstract: A high profile rocker arm assembly increases rocker arm strength, minimizes rocker arm weight and enables improved valve lash adjustment. The rocker arm assembly comprises a rocker arm, a cross shaft, and an externally mounted roller tip. The cross shaft incorporates certain offset structure so that when adjustment thereof is made, valve lash adjustment is quickly and easily achieved. This eliminates the need for an adjuster stud and nut on the rocker arm. Several different pillow blocks may function to operatively retain the device.
