Previous rocker arm minimum length specification - 2.865 inches
Rule update, effective immediately - 2.850 inches
The overall tolerance and critical dimensions (center to center, center to push rod journal, to measurable weight) have not changed but a recent adjustment in the stamping of our rocker arm has reduced the overall length of the trim "tab." The trim "tab" is simply the small gate of material at the very tip of the rocker arm that functions to control the location of the part during the stamping process.
