GoJakModel G4520

Much like the other reviews I can't find many faults with these casters, especially when compared to it's competitors, and as the company that makes these (Zendex) says "they're the faster casters." The price was the real catching point to me, at about 200 a pop, these aren't something that I just throw money at and now I personally may use them maybe a half dozen times a year. I tried using cheaper variants made buy harbor freight, and that was a mistake, although the harbor freight ones worked, there was multiple steps to get the set up to just lift up/down, and then the steel casters wouldn't roll - even when all four tires were manually placed in the direction of the roll prior to lifting/moving. I tried to find casters that I could replace and would work better with the harbor freight ones, but at 25 dollars each, I quickly realized the GoJak was a better/cheaper option after all.Pro's:Made in the USAHeavy, high quality - never fails to operate/doesn't jamVery easy to operate, one flip of the switch and you're already lifting/lowering the vehicleHandles large and wide or narrow and thin tiresLow profileCaster wheels are very smooth and roll easy with one person pushing and don't need set up manually in the direction of the roll prior.Con's (many are debate-able, as they could be pro's for some)PriceHeavyPrevent the ability putting close to walls/other objects (due to jack feature)Needs to be carefully placed - putting too close to tire can damage the Gojak and tire wall (thus voiding Gojak warranty)Works best on clean/flat concrete - textured surfaces slow it down, rolling on wood seriously deteriorates ease. Surfaces like rutted pavement, damaged concrete, or any type of coarse surface regardless of how hard limits movement.Foot pad requires strength to maneuver (can't use hand to start the jacking)Foot pad is small (for my clown feet)As stated above, the pro's and con's are negligible, and for what it's supposed to do it does a great job. I use these for moving a travel trailer over to allow more access in a relatively small area. Yet, the ease and relatively little effort I needed to exert by myself made it so worth it. Another chore I use the Gojak for is lifting my low profile car up on one side. This allows me to place wooden blocks under the frame and then lower the car down so I can drain the oil without needing a floor jack. I would recommend these to anyone who needs to move a car/trailer on a flat hard surface.

This GoJak is a must for anyone that owns a truck or Jeep that has oversized tires and wheels. I bought these strickly for rotating my tires on my truck. Once vehicle is jacked up and on jack stands, it's so easy to mate the GoJak to your tire, jack the lever with your hand lifting the tire off the studs. Easy to flip small lever in opposite direction to lower the tire. I like washing my wheels and tires on both sides before reinstalling them. Easy to then use the GoJak to lift tire back up from pavement and install back on vehicle. What's nice is when tire is on GoJak, you can rotate the wheel to line up holes with wheel studs because of the rollers on the Gojak. Great design and the casters roll smoothly and rotate for easy turning. Well worth the money not having to injure your back. Makes rotating big heavy tires a breeze.

They are pricey compaired to other models but with these being the low profile they are worth every penny. The casters are more robust than the pictures lead on and they fit under low profile cars like a c8 stingray just fine. I bought these for my shop and they have come in very handy to move cars with dead battiers and other immobilized issues

work,s fine for my big truck,s

Very heavy duty units. It even shocked me. They work good but do to the weight on them they don't roll easily. Being I have a Corvette I have to be real careful on where I push on the car. Bottom line they work are very simple to use and I'm happy with them.UPDATE: sold the Vette and have a Camaro now. Metal body is a whole lot easier to push around as the body is stiffer.
