Valves & Parts

60 products

Our Valves & Parts for Harley-Davidson range covers the intake and exhaust valves, guides, keepers, seals and springs that make up the cylinder head across Sportster, Dyna, Softail and Touring engines. Iron Stable is run by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, so every component here is selected for correct stem sizing, face angles and material specifications to suit Evolution, Twin Cam and Milwaukee-Eight Harley-Davidson motors. Feuling and S&S lead this section with their engineered valvetrain parts favoured by performance builders and professional workshops, giving you high-flow options, stronger springs and reliable guides for stock rebuilds and tuned combinations alike. Whether you are refreshing a high-mileage head, building a cam-and-head stage kit, or rescuing a bent valve, you will find the right part here. UK delivery is free on orders over £100.
