About This Product
This left-side swingarm bearing locknut is a specific hardware component required for the rear suspension assembly on late 1974 to 1981 Sportster models. It is a direct replacement for OEM 47514-74. In the workshop, we know that these locknuts are vital for securing the swingarm pivot and ensuring that the rear end of the bike remains stable and tracking straight. Over time, threads can become damaged or the nut can become rounded off during maintenance. Replacing it with this high-quality MCS part ensures your swingarm bearings are properly retained, maintaining the handling characteristics and safety of your classic ironhead Sportster.
Manufacturer part number: 518121.
