WHEEL BOSS wheel-end components offer an improved solution to wheel-end problems. The WHEEL BOSS wheel-end components support longer bearing life, greater fuel efficiency, and reduced maintenance costs. These components include a grease seal, non-vented hub cap, and adjusting nut. All of these components are compatible with "N" trailer axles. With these components a typical oil or semi-fluid grease lubricated wheel-end is converted to a more durable and longer lasting greased wheel-end system, when combined with Timken bearings. All of the components have been designed and tested to perform in the most rigorous environments.
