About This Product
This MCS bearing collar is a high-quality replacement part for both front and rear star hubs. It is designed to fit 1936 through 1966 Big Twin models, providing the necessary support and positioning for the hub's roller bearings. Over decades of use, these collars can become grooved or worn, which compromises the integrity of the wheel assembly. Replacing them with this precision-machined part ensures your bearings have a smooth, stable surface to ride against. This collar is a direct replacement for OEM part number 43561-39 and is also identified by part number 900623.
Manufacturer part number: 900623.
