There is always a premium on storage space, but that doesn't mean your hobby car has to sit out in the elements in your driveway. Safely move the car into a position it could not safely be driven into with the black bull 2-Piece ccar dolly set. Get the most use out of your garage or storage space. Install a single car dolly under each front or rear tire to move any car backwards, forwards, or sideways. Each steel car dolly can bear a weight of up to 1000 pounds so this dolly set can bear the load of a car that weighs up to 4000 pounds with tires up to 14 inches wide. 3.5 Inch steel casters with swivel action bearings easily roll 360-degrees in any direction.
