MCS Star Hub Parts

14 products — part of all Star Hub Parts

MCS star hub parts give Harley-Davidson owners and restorers the specialist components needed to rebuild and maintain the distinctive star-pattern wheel hubs used on pre-1966 Harley-Davidson models. The star hub is one of the most recognisable design elements of vintage Harley-Davidson wheels — its multi-point flange profile is unique to the era and cannot be replicated with later-style spoke flanges, making it a key authenticity detail for concours-level restorations and period-correct custom builds. MCS supply star hub components including the bearings, axle spacers and related hardware to the dimensional specifications of the original Harley-Davidson design, recognising that sourcing correct parts for these early hubs can be a genuine barrier to restoration completion. Correct dimensional matching is critical in a wheel hub — incorrect bearing sizing or spacer thickness affects wheel bearing preload and ultimately road safety. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries MCS star hub parts alongside a comprehensive vintage and classic Harley-Davidson components range.
