The Model 5211 is the workhorse of the GoJak auto jack / dolly product line. The basic self-loading dolly design was developed twenty years 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 can lift and move wheel weights up to 1,300 lbs. (up to 5,200 lbs with four units). Capable of lifting tire widths up to 11 inches wide and up to 34 inches tall, the unit accommodates a very large percentage of the passenger cars and small trucks sold today. It uses a bi-directional linear ratchet for the jack portion and four 4-inch diameter heavy-duty doubleball raceway casters. Available in left and right hand units.
