518123 Bearing spacer, outer. swingarm

This outer swingarm bearing spacer is designed for late 1974 to 1981 Sportster models, providing the necessary clearance and alignment for the rear suspension pivot. It serves as a direct replacement for OEM 47517-74. When servicing the swingarm on these Sportsters, it is common to find these spacers pitted or worn, which can lead to unwanted play in the rear fork. Installing a fresh spacer ensures that the bearing assembly is properly preloaded and the swingarm is centered in the frame. This is a simple but critical part for maintaining the smooth suspension action and predictable handling required for a safe ride.
