Quickly and easily adjust your valves with this screwdriver and 13mm socket all in one tool. Can be used on all VW rocker arms using 13mm Jam Nuts for increased accuracy and the convenience of using one tool.

The adjustment tool features a "window" in its socket so the position of the screwdriver blade holding the adjustment screw can be seen as the 13mm jam nut is tightened. The unique handle pivots from one side to the other, always keeping the window visible.
