Save time, energy, and your back when moving your boat lift with the Extreme Max Boat Lift Wheel Kit! With countless mounting configurations, the kit's two wheel assemblies mount to any rectangular frame from 2" wide to 4" wide and up to 6" tall and holds standard dock and lift wheels with a minimum 1-5/8" axle opening. Position the wheel kits along the frame in a location that allows you to easily pivot the dock or lift onto the wheels, then let it carry the weight as your maneuver it into the desired position. Each kit contains two wheel axles and mounting assemblies; wheels sold separately. Extreme Max has wheels available should they be needed, see Extreme Max 3005.3729 Plastic Roll-In Dock/Boat Lift Wheel.
