About This Product
This white color-coded steel hub bearing spacer is a critical component for front and rear hub maintenance on 1973 to 1983 Harley-Davidson models. Measuring 4.448 inches, it replaces OEM 43603-78 and is designed for use on 45 inch Solo, Big Twin, and Servi-Car models. Achieving the correct bearing preload is essential for wheel health, and this precision spacer allows for accurate setup of the hub assembly. Built from high-strength steel, it provides the durability needed for classic bikes. Whether you are performing a full restoration or a routine bearing replacement, this spacer ensures your vintage hub meets original factory specifications.
