This jack can be scooted under a bumper that is almost touching the ground and will raise the end of a heavily loaded vehicle to a height of 37 (just over 3 feet), giving ample room to remove high centers, fill voids, dig out sand or muck, put on tire chains or change a flat.
If you slide off the road, you can maneuver your vehicle out of a ditch by placing this jack in a horizontal position against the bank and pushing sideways.
