Jims Valve Keys

3 products — part of all Valve Keys

JIMS USA manufactures precision valve keys for Harley-Davidson engines with the same exacting standards that have made their specialist tools a workshop staple since 1967. Their range covers Evolution Big Twin and Sportster XL models from the late 1950s through 2004, Twin Cam engines from 2005–2017, and current-era Sportster XL models up to 2022 — ensuring that whether you are rebuilding a vintage Ironhead or refreshing a modern Twin Cam, correctly sized and dimensionally accurate keepers are available. Valve keys are small components with an outsized role: they lock the spring retainer to the stem and must seat perfectly to prevent valve train instability under load, making precision manufacturing essential rather than optional. JIMS distinguishes itself from generic aftermarket suppliers through decades of exclusive focus on Harley-Davidson engine and drivetrain components, giving builders confidence that every part is engineered for the application rather than adapted from a generic catalogue. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks JIMS engine components. Browse the full Jims Valve Keys range below.
