About This Product
When you are rebuilding the front or rear end of an early Ironhead or K-model, you cannot overlook the small stuff. This left-side wheel bearing lock nut from MCS is a direct replacement for the original hardware, ensuring your bearings stay exactly where they need to be. It is designed to fit 1955 to 1978 K-models and XL Sportsters. Machined to precise tolerances, it serves as a reliable alternative to OEM number 41201-55. Keeping your wheel assembly tight is critical for safety and handling, and this lock nut provides the factory-spec fit you need for a proper vintage restoration or routine maintenance job.
Manufacturer part number: 512222.
