ABSTRACT:
The invention is a jack stand for using the drive power of a vehicle to raise the vehicle off the ground. The jack stand has a retention device such as a cradle to engage an undercarriage member of the vehicle. The retention device is connected to a post which in turn is mounted to a base plate. The base plate is configured to allow the post to pivot to a vertical position as the vehicle is driven over the jack stand so that the post raises the vehicle.
