Abstract: A stabilized jack assembly is a device utilized to elevate and stabilize a vehicle. The device eliminates the need for the user to venture beneath the vehicle before the vehicle is stabilized. The device includes a planar base that provides stability for the device on a flat surface. A scissor lift assembly is utilized to elevate and lower a mounting head that is placed into contact with the vehicle. A threaded spindle is axially engaged through the scissor lift assembly and is rotated in order to elevate and lower the mounting head. A plurality of support struts is utilized to stabilize the device once the vehicle is elevated. The plurality of support struts is removably engaged into a plurality of strut braces on the planar base. The plurality of support struts is able to automatically engage the plurality of strut braces when the vehicle has been sufficiently elevated.
