Crankshafts & Parts

137 products

Our Crankshafts and Parts range for Harley-Davidson covers flywheel assemblies, rod kits, pinion shafts and related internals for Sportster, Dyna, Softail, Touring and Evolution Big Twin motors. Supplied by Iron City Motorcycles, an Iron City authorised HD dealer in Leeds, this performance-focused section is led by S&S with Feuling also represented. A balanced, true crankshaft is the heart of any strong Harley-Davidson motor, and upgrading during a rebuild unlocks smoother running, more reliable bottom-end life and in many cases a bigger stroke for extra torque. Whether you are rebuilding a high-mileage Touring motor, stroking a custom Softail or building a hot-rod Dyna, our catalogue has the rotating assemblies you need. Every order ships from UK stock with fast despatch and workshop support from Leeds. Browse the full range below.
