Every mechanic, car collector, or shop owner knows the specific frustration of trying to move a dead vehicle. It’s usually heavy, the tires might be flat, and it is almost always sitting exactly where you don’t want it to be. If you are working alone, shuffling a two-ton vehicle into a tight corner is a recipe for back pain and wasted hours. GoJak wheel dollies are specifically designed to move disabled vehicles, making the process much easier than traditional methods.
For years, the standard solution involved dragging out a heavy floor jack, lifting each corner of the car one by one, and sliding a wheel dolly underneath. It’s a slow, four-step process that kills productivity. This is precisely the problem the GoJak Model 6313 aims to solve.
Promising to turn a disabled vehicle into a smooth-rolling cart in seconds, the GoJak 6313 is often cited as the gold standard for vehicle positioning jacks. GoJak wheel dollies are designed for use in various settings, including shops and parking garages, making them a versatile solution for vehicle movement.
But with a premium price tag compared to budget imports, is it actually worth the investment? In this review, we break down the specs, the unique “left-hand” design features, and what real customers are saying about this American-made tool.
GoJak Model 6313 Self-Loading Dollies
With steel rollers, wider axles, and two heavy-duty 5 in. and two 4 in. diameter double-ball raceway casters
What is the GoJak Model 6313?
The GoJak Model 6313 is a gojak wheel dolly, a self-loading vehicle dolly designed to lift and move heavy vehicles without the need for floor jacks or additional equipment. Manufactured by Zendex Tool Corp, GoJak has been the industry standard since 1984.
Unlike hydraulic dollies that can leak fluid over time, the GoJak uses a mechanical ratchet system. The GoJak operates on the principle of mechanical leverage and gravity, requiring no compressed air, electricity, or hydraulics. You simply slide the unit around the tire, then apply mechanical leverage by stepping on the foot pedal progressively, which squeezes the vehicle tire between the rollers and lifts the vehicle smoothly off the ground.
Only the tire is contacted during this process; the rollers touch only the vehicle tire and do not contact the frame or undercarriage. This design ensures the tire lifts smoothly and safely, and the rollers only touch the tire, preventing any contact with the vehicle’s frame. The Model 6313 specifically is the “workhorse” of their lineup, engineered to handle heavier vehicles like light trucks and SUVs with wider tires.

Key Features and Specifications
The Model 6313 isn’t just a slightly larger version of the standard dolly; it is built for serious weight and challenging environments. GoJak offers several options and versions to accommodate different vehicle types and user needs, and they also offer a variety of packages and accessories to ensure customers have comprehensive solutions for their needs.
For example, the GoJak Wheel Dolly Shop Kit includes four G6313 GoJak Wheel Dollies and one G678R Rolling Storage Cart, providing a complete setup for professional shops or garages.
Here is a breakdown of why this specific model stands out in the crowded market of shop tools.
Massive Weight Capacity
The "6313" in the name refers to its specifications. It is rated for vehicle curb weights up to 6,300 lbs. That breaks down to 1,575 lbs per wheel. This capacity allows you to move not just compact sedans, but full-size muscle cars, modern SUVs, and even some light-duty trucks with confidence.
Tire Width Compatibility: The Rollers Touch Only the Tire
One of the most significant limitations of standard dollies is that they cannot handle wide drag radials or off-road tires. The Model 6313 is designed to accommodate tire widths up to 13 inches and tire heights up to 36 inches. Whether you are moving a Corvette with wide rear rubber or a lifted Jeep, this dolly offers the necessary clearance. The rollers touch only the tire, and no contact is made with the vehicle's frame or undercarriage.
Self-Loading Mechanism
The defining feature of the GoJak is speed. The double-ball bearing raceway casters allow you to slide the jack in from the side. Using the bi-directional linear ratchet, you use your foot to jack up the wheel. There is no bending over, no pumping a hydraulic handle, and no need to pre-lift the car. The GoJak wheel dollies are easy to position and operate, even in tight spaces or with locked vehicles, making them highly adaptable and convenient.
The "Left-Hand" Advantage
A unique aspect of the Model 6313 kit is the inclusion of specific “left-hand” and “right-hand” units. While this might sound like marketing jargon, it serves a critical practical purpose.
If a car is disabled and the steering wheel is turned to an extreme angle, especially affecting the front wheels, a standard dolly pedal might get trapped inside the wheel well, making it impossible to pump. The “left-hand” version orients the foot pedal to point out of the wheel well in these situations, allowing easy access to the pedal even when the front wheels are turned or locked.
This thoughtful design element ensures you can move a crashed or locked-steering vehicle regardless of how the wheels are turned, and enables precise positioning of the vehicle even in challenging situations.

Who needs a Gojak Wheel Dolly?
While the price point might deter the casual DIYer who only changes oil once a year, the GoJak 6313 is an essential piece of equipment for several specific groups. Its design lifting helps make moving vehicles stable and safe for users in various scenarios. GoJaks feature a low center of gravity and a robust steel frame, which contribute to their stability during operation.
Professional Mechanics and Body Shops
Time is money in a professional shop. If a non-running car is blocking a bay, it needs to be moved immediately. The ability to move a car solo without waiting for a second technician to help push justifies the cost quickly.
Car Collectors
If you have more cars than garage space, "stacking" cars is a necessity. These dollies allow collectors to push vehicles sideways, tight against a wall, effectively doubling usable floor space.
Tow Truck Operators
The Model 6313 is particularly popular in the towing industry. The oversized casters provide increased ground clearance, about 2-1/2 inches more than the 5000 series. This extra clearance is vital when pulling cars up the incline of a flatbed truck without the dolly bottoming out.
Design and Build Quality
In a market flooded with cheap overseas imitations, build quality is where GoJak separates itself. The unit is designed, manufactured, and tested in the USA.
The frame features high-strength galvanized steel rollers and upgraded 1-3/4" wide axles. The casters are made from heavy-duty nylon, which offers a good balance between durability and floor protection.
The pedal design also features a 5-degree offset. This small engineering tweak provides additional foot-to-tire clearance, preventing your boot from rubbing against the rubber while you are jacking up the car.

What Customers Are Saying
To get a true sense of the product, we looked at feedback from users who have put the Model 6313 through its paces.
The Good
Reviews are overwhelmingly positive regarding the unit's sturdiness. Users frequently describe it as a "workhorse" and praise the smooth rolling action.
- Ease of Use: Many reviews highlight that lifting a tire is effortless compared to hydraulic alternatives.
- Mobility: The large caster wheels are a hit, with users noting that they roll easily even on surfaces that aren't glass-smooth, such as older shop floors with cracks or expansion joints.
- Durability: Long-time users appreciate that there are no hydraulic seals to blow out after a few years of use.
The Bad
No product is perfect, and there are a few valid critiques to be aware of.
- Tire Width Confusion: While rated for 13 inches, a few users noted that it is a very tight fit. One reviewer mentioned that according to the manual they received, it was optimal for 12-inch tires, suggesting 13 inches is the absolute maximum.
- Maintenance: The mechanical ratchet requires lubrication. Some users noted that the inner bar comes with heavy grease that acts as a "dirt magnet" in a dusty shop, requiring regular cleaning and re-oiling to keep the action smooth.
Comparison: GoJak vs. The Competition
You can find vehicle dollies on Amazon for $100, so why pay over $450 for a pair of GoJaks?
The cheaper alternatives generally use hydraulic cylinders. While cheaper upfront, these seals often fail, rendering the jack useless. Furthermore, budget dollies typically have smaller steel wheels that get stuck on the smallest pebble or zip tie on the garage floor.
The GoJak 6313 uses a mechanical system that is virtually fail-proof if kept clean. The larger nylon casters and American steel construction mean you are buying a tool that will likely outlast the car you are moving.

Verdict: Is the GoJack Wheel Dolly 6313 Worth It?
If you only need to move a lightweight car once for a restoration project, you might get by with a cheaper set of dollies. However, if you value your time, your back, and the safety of your vehicle, the GoJak Model 6313 is the superior choice.
For professional shops, tow operators, or serious collectors dealing with heavy American muscle or SUVs, the high weight capacity and "left-hand" utility make this an investment that pays for itself in hassle-free mobility. The GoJak wheel dolly is a revolutionary tool designed to simplify the process of moving and positioning disabled vehicles in tight spaces, such as a parking garage or workshop.
With its innovative design and mechanical leverage, this wheel dolly allows users to lift and maneuver a vehicle tire effortlessly. The foot pedal is engineered for progressive operation, ensuring that the tire lifts smoothly with minimal effort. This feature is particularly useful when dealing with front wheels or vehicles with a low center of gravity, as it provides precise control during the lifting process.
One of the standout features of the GoJak wheel dolly is its use of rollers that gently cradle the tire. As the rollers touch the surface of the vehicle tire, the foot pedal orientation ensures that the lifting motion is both smooth and efficient.
The nylon ANSI ICWM 2012 certification guarantees that the product meets high standards of durability and performance, making it a reliable choice for professionals and enthusiasts alike. Whether you're working in a parking garage or a home workshop, the GoJak wheel dolly is an essential tool for handling disabled vehicles with ease.

Final Thoughts
The G6520 kit is a popular option for those looking to enhance their vehicle maintenance setup. This kit includes a GoJak wheel dolly with a max tire capacity that accommodates a wide range of vehicles.
The compressed air compatibility further enhances its performance, allowing for quicker and more efficient operation. By leveraging mechanical leverage and a well-designed foot pedal, the G6520 kit ensures that lifting and moving vehicle tires is a hassle-free experience.
For those who want to learn more about the GoJak wheel dolly and its features, it's worth noting that the product is designed to meet the ANSI ICWM 2012 cert standards, ensuring safety and reliability.
Whether you're adding products in the cart for a professional garage or personal use, this item stands out as a standard right choice for anyone seeking a high-quality wheel dolly. Its ability to handle only the tire with precision and care makes it an indispensable tool for automotive professionals and DIY enthusiasts alike.
