The Black Ice Three-Piece Drivable Snowmobile Dolly comes with two ski dollies and one track dolly to give you the option to drive or manually position your sled where you want it in the off season. All three dollies are manufactured from powder-coated steel. The front dollies have two oversized wheels and ski hooks, and are designed to not only lift carbides but also protect the surface from excessive wear. The rear dolly features four swivel casters for easier manual movement. Drive your snowmobile up to 5 MPH using just the two front ski dollies. Place each ski through the square dolly hole and secure with the attached ski hook to keep it elevated in position. There is no need to place the rear dolly, as the track must contact the ground in order to drive the snowmobile carefully. Manually position your snowmobile where needed in your garage or shop by positioning the two front ski dollies, then lifting the track up onto the rear track dolly. With all three contact points resting on the dollies, you’ll be able to precisely move your snowmobile around your space.
