Crankshafts And Gears

60 products

Our Crankshafts and Gears range for Harley-Davidson transmissions covers main shafts, counter shafts, transmission gears and related rotating components for Sportster, Dyna, Softail and Touring models. Supplied by Iron City Motorcycles, an Iron City authorised HD dealer in Leeds, this section is led by genuine Harley-Davidson parts with correct hardening, tolerances and factory finish for a long service life. Transmission internals are not a place for compromise, and using OE components during a gearbox refresh gives the best shift quality and durability. Whether you are rebuilding a jumping-out-of-gear Big Twin, fixing noise in a high-mileage Touring bike or refreshing an older Harley-Davidson 5-speed, we stock the factory components you need. Every order ships fast from UK stock with expert support from Leeds. Browse the full range below.
