Abstract: A lift jack is provided for use with a vehicle having a structural member on the underside of the vehicle, which structural member defines a transverse rotational axis. An elongated body member defines a longitudinal axis, and has a top end portion and a bottom end portion. The longitudinal axial length of the elongated body member is greater than the height of the transverse rotational axis above the ground. The bottom end portion has a radiused lifting surface and a generally planar foot extending contiguously from the radiused lifting surface, toward a second lateral edge of the bottom end portion. The elongated body member may be rotationally mounted on the vehicle by attachment of the top end portion to the structural member.
