The BlueSpot 10 PCE Bearing Race and Seal Driver Kit is suitable for the installation of straight races and seals into brake disc hubs without damage to the bearing or axle housing. The collars will fit most standard wheel bearing sizes, including 4x4 vehicles and are made from machined aluminium. The kit comes in a handy carrying case for quick and easy storage. The adaptor should sit snugly within the race with minimal movement to avoid any damage to the axle housing. The seal can then be installed once the bearing is placed within the race with the same sized adaptor.
