Unitec GoJak Vehicle Dollies: Move Any Vehicle with Confidence

When it comes to repositioning vehicles in tight shop spaces, garages, or on tow calls, few tools are as practical or as proven as the Unitec GoJak line of vehicle dollies. Designed, manufactured, tested, and proven in the USA since 1984, Unitec GoJak dollies have earned a reputation among professional technicians, collision shops, show car enthusiasts, and towing operators as the go-to solution for effortless vehicle movement.

The Self-Loading Advantage

What sets Unitec GoJak vehicle dollies apart from conventional wheel dollies is their patented self-loading design. Rather than requiring a separate floor jack to lift each wheel before sliding a dolly underneath, GoJaks operate on the principle of a quick-action, bi-directional, double-pawl ratchet mechanism. A simple press of the foot pedal "squeezes" the vehicle tire progressively, lifting the wheel off the ground — all in seconds, and without air, oil, or electricity. This self-contained mechanical action means one person can mobilize an entire vehicle quickly and safely.

A Model for Every Vehicle

Unitec offers a range of GoJak dolly models sized to match the job at hand:

• GoJak Model 4520 (Super-Slick): All-steel construction with double ball bearing nylon casters, rated up to 4,500 lbs. total vehicle weight (1,125 lbs. per wheel), accommodating tires up to 20" wide. Originally developed for the race car industry, this low-profile model is a favorite for show cars and garage storage.
• GoJak Model 5211: A versatile mid-range option handling tire widths up to 11", equipped with heavy-duty double-ball raceway casters for smooth, controlled movement in any direction across workshop floors.
• GoJak Model 6313: The most versatile and strongest in the passenger car lineup, rated for vehicle weights up to 6,300 lbs. (1,574 lbs. per wheel) with tire widths up to 13" and heights up to 36". It features steel rollers, wider axles, and a 5-degree offset pedal for extra foot-to-tire clearance — especially useful when loading vehicles onto flatbed trucks.
• GoJak Model 7016 (SUV): The largest and heaviest-duty GoJak, rated for curb weights up to 7,000 lbs. with tire widths up to 16". Featuring high-strength steel rollers, super-wide 2‑3/4" axles, and super heavy-duty GF nylon double-ball bearing raceway casters, the 7016 is specifically engineered for light-duty trucks, SUVs, and even dual rear tire assemblies.
