MCS Gascaps

49 products — part of all Gascaps

MCS fuel caps cover the full sweep of Harley-Davidson history, from 1936 through to modern fuel-injected platforms, making them one of the most comprehensive gascap ranges available for UK riders. As a catalogue supplier with broad model coverage rather than a niche customising brand, MCS approaches gascaps as a practical replacement and upgrade solution — whether you need a direct-fit vented cap for a carburetted Shovelhead or Panhead, a sealed non-vented unit for a fuel-injected Milwaukee-Eight, or a universal fitment for a custom project. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries the MCS gascap selection to serve riders across generations of Harley-Davidson ownership. Coverage spans 36-82 vintage Big Twins, 83-95 and 96-18 model year machines, and universal designs that suit one-off builds where stock tank fitments have been modified. Alongside chrome and black finishes, MCS provides the straightforward, no-fuss replacement options that keep a restoration on schedule and a custom build moving forward without hunting obscure part numbers from multiple suppliers.
