If you have worn solid urethane or rubber bogie wheels, you can send them to us, and we'll recover them with heavy-duty polyurethane. Our 12-step process creates a superior bond between the urethane and the hub, which helps to prevent "chunking". If you have pre-existing rubber bogie wheels, you'll notice a significant improvement in performance after they are covered with our polyurethane. If the bogie wheel you need is not listed, please check with your FallLine Sales Representative, as we are constantly updating our inventory of molds.
