The Model 5211 is the workhorse of the GoJak® auto jack / dolly product line. The elemental self-loading dolly design used to be developed two decades ago and the specifications have recently been improved from 5,000 to 5,200 lb capacity. The 5211 Series GoJak® is a proven and reliable product that may lift and move wheel weights as much as 1,300 lbs. (as much as 5,200 lbs with four units). Able to lifting tire widths as much as 11 inches wide and as much as 34 inches tall, the unit contains an overly large percentage of the passenger cars and small trucks sold lately. It uses a bi-directional linear ratchet for the jack portion and 4 4-inch diameter heavy-duty doubleball raceway casters.
