Head Bolts

41 products

Head Bolts for Harley-Davidson secure one of the most critical joints in your engine, so quality matters. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries head bolt kits from Colony, Gardner-Westcott and S&S to cover Big Twin and Sportster powerplants spanning decades. Whether you are rebuilding a 1948-1984 Panhead or Shovelhead, freshening up a 1957-1985 Ironhead Sportster, or torquing down a 1991-2017 Evolution or Twin Cam top end, you will find the correct fastener kit here. Options range from chrome-plated OE replacements to high-strength performance bolts for high-compression builds. Correct head bolt selection is essential for reliable sealing and long engine life.
