About This Product
This rear wheel hub spacer is a critical component for proper bearing preload and wheel alignment on 3/4 inch axles. Measuring 4.434 inches, it features the yellow OEM color code for easy identification during assembly. It serves as a direct replacement for OEM 43605-78 and is designed for cast wheel applications. This spacer fits 1973 to 1985 FX models, 1980 to 1985 FXB, FXSB, and FXEF models, as well as 1987 to 1991 FXR, Softail Custom, and Fat Boy models. Ensuring your axle bearing sleeve is in good condition is essential for smooth wheel rotation and long bearing life, preventing unnecessary friction and heat buildup.
Manufacturer part number: 919673.
