Billet Rocker Arm Supports +.030


These billet rocker arm supports are designed to withstand high lift cams.When performance headwork is done, sometimes the valve stem protrusion exceeds factory spec., with high lift cams those conditions will position the rocker tip closer to the edge of the valve stem at full lift. Our solution is to move the rocker arms out .030" so the rocker tip hits in the middle of valve stem. This prevents side loading of the valve stem. Fits Twin Cam® Rocker Boxes.


The .030 over supports require the rocker shaft notch to be clearanced for the mounting bolt. The .030" offset moves the rocker shaft into the hole.
