The jack is inflated via a hose that connects to the vehicle's tailpipe. As soon as the vehicle's engine is started, the jack will start to inflate.
When developing this product, the design engineers recognized that conventional jacks were not suited to all types of terrain. In unstable areas of mud, sand and snow, the X-Jack offers a wider footprint to avoid sinking, and uses specially designed, triangular shaped feet to keep the unit firmly grounded. For ease and greater stability, the X-Jack is designed to be safely placed under the side of the body rather than positioned under an axle like a traditional jack.
