ABSTRACT:
A rocker arm includes a first end including a substantially horizontal wall having a receptacle formed therein. A second end of the rocker arm is spaced from the first end and includes a substantially horizontal wall for engaging a valve stem. A pair of spaced substantially parallel vertical sidewalls extend between the first end and the second end. In one embodiment, the sidewalls define a width between the first end and the second end that is less than each of the widths of the first and second ends. In another embodiment, a transverse wall extending between the sidewalls is formed in the second end. In yet another embodiment, rocker arm alignment walls are formed in the second end independently of the sidewalls.
