This kit includes brand new wheel bearings and the driver kit to install them! These quality bearings are an exact fit and will outlast the stock bearings. Changing your wheel bearings can be a real pain without the correct tools. Get the job done fast and correctly using this Torpedo installation and removal tool set by Quad Logic. We developed this tool to both remove and install the Front or Rear wheel bearings from your Polaris ATV. It includes a holder for the rear hub and then a driver to press the old bearing out of the hub. Once removed, flip over the hub and driver and press in the new included bearings. The dual sided driver/installer torpedo tool works for both!
