Valve Keys

18 products

Valve Keys for Harley-Davidson are the small but critical split-cone retainers that lock each valve spring to the valve stem. Without correctly fitted valve keys, spring pressure cannot be transmitted to the valve, making them essential during any head rebuild or valve-spring upgrade. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries valve keys from Kibblewhite, MCS and Feuling for Big Twin, Sportster and Twin Cam engines. Whether you are replacing worn keys during a routine top-end service or fitting high-performance titanium retainers as part of a race build, these precision-ground components ensure secure valve-spring retention at all engine speeds.
