Protect your carbides and garage floors with the Pro Series Snowmobile Dolly System from Extreme Max! The system's clever design slides underneath the snowmobile's skis and hooks into the ski loop, providing a set of drivable wheels to easily maneuver your sled around the garage, yard, and trailer. The oversized wheels easily handle traveling over grass and gravel surfaces without worry of wearing down the snowmobile's ski carbides or scratching the surface underneath the skis. Each dolly features a length adjustment to allow the perfect fit from spindle to ski loop. Pro Series Snowmobile Dollies are drivable up to 5 MPH and work with any modern snowmobile up to 650 lbs.
