About This Product
This MCS swingarm bearing and cup assembly is designed for the specific requirements of late 1970s Sportsters. It fits late 1974 to 1981 XL Sportster models and is used on both the left and right sides of the swingarm pivot. The kit includes the bearing and the matching cup, providing everything you need to refresh one side of the pivot. Since these models require two units for a full service, it is a good idea to inspect both sides when you have the rear end apart. This assembly replaces OEM 47521-74 and 518125, offering a high-quality replacement that restores smooth movement to your rear suspension and helps maintain proper wheel alignment.
Manufacturer part number: 518125.
