This low profile jack starts at 2-3/4 inches and raises up to 15-1/2 inches. Includes a steel safety bar that slides into the lift arm to secure the jack in the max height position. Nylon front and rear wheels provide quiet movement. 4,500 lbs lifting capacity is great for unibody vehicles where jack stand positioning is difficult. The perfect jack for the auto enthusiast that works on classic cars and/or lowered cars.
