About This Product
When the front end starts feeling loose or notched, it is time to refresh the steering head. This MCS frame neck bearing, race, and seal kit is a complete solution for a full service on one motorcycle. It features 30mm internal diameter bearings and includes the upper and lower bearings, races, and seals. These are OEM-style seals designed to keep grease in and road grime out much better than the old-fashioned metal shields. This kit, part number 577074, is a direct replacement for reference 45700009 and fits 2014 to 2026 FLT Touring models and Trikes. It is essential maintenance for keeping your heavy-duty cruiser handling predictably on the road.
Manufacturer part number: 577074.
