If you're looking for the best car dolly for ease-of-use, look no further than this GoJak model (part number G6313L). It easily outshines similar products because it is self-loading, supports up to 1,575 lbs. per jack, & is designed to quickly lift your vehicle in fewer strokes than other jacks.\r\n\r\nWhy We Like It - GoJak Model G6313L\r\nThe GoJak heavy duty jack dolly is a self loading wheel dolly that is rated for up to 6,300 lbs. (1,575 lbs. per wheel) and supports tire widths up to 13\u201d. It uses double ball bearing nylon castors to ensure you can easily move your vehicle.\r\n\r\nPerformance\r\nThe GoJak dolly can outlift even our #1 pick for best car dolly, the 5060 Tire Skates Bearings Moving. This powerhouse supports up to 1,575 lbs. per dolly (with four units it can lift a car up to 6,300 lbs.). Unlike a normal dolly, where you would have to use a separate jack to lift up the vehicle & load it, this model is self-loading: simply place the dolly under the tire and jack it up off the floor, with no additional tools necessary. Once you have the vehicle loaded, easily move it on the double ball bearing castors.\r\nDesign\r\nUnlike other dollies, this model is self-loading, so you won't need an additional jack to load a vehicle (you will, however, need additional units as these are sold individually). The GoJak G6313L is only available in purple, so if red is more your color you will have to opt for the Inches Premium Skates Bearings Furniture instead. This dolly is offered in both a left and right-handed version, so you can choose the best one for your needs. It also features the largest casters in the GoJak line of products (for easier movement).\r\nValue\r\nThe price point is the biggest downfall of this product. Costing $309 per unit, this means to lift a car by all four axles you will have to spend a whopping $1560 (for comparison, the WEN 73017 Vehicle 1500 Pound Capacity only costs $46.11 for two units)! It scores a 4.6\/5 in the customer reviews, so people are happy with it overall, but we still find it hard to justify the massive leap in price that is based mainly on the fact that this dolly is self-loading.\r\nGoJak Model G6313L Wrap Up\r\nThe GoJak Model G6313L is an amazing, heavy-duty efficient product that completely does away with the need for a separate jack, but its high price point will be the end of the road for most consumers. There are much more affordable dolly options available (though you will have to buy a jack as well). This is definitely a high-end product, but based on the price, we can only recommend it for professional or extreme hobby use.
