Abstract
A scissors jack which has improved formed gear teeth which allow a jack to be retracted to a very low profile so that it can be placed under the vehicles. The teeth of the lower pivot arms are formed so as to extend one direction and the teeth of the upper pivot arms are formed so as to extend in the opposite direction from the teeth of the lower pivot arms so that when the jack is in the down position, the gear teeth on the upper and lower pivot arms can pass each other and thus allow the jack to have a very low contour.
