Ignition Timer Driven Gears

2 products

Our Ignition Timer Driven Gears for Harley-Davidson cover the small but critical gear that drives the ignition timer on vintage Big Twin and Sportster engines. Iron Stable is operated by Iron City Motorcycles, an Iron City authorised HD dealer in Leeds, so each Harley-Davidson part we list is sourced through trusted channels. Fitment spans 1937–1969 OHV Big Twin, 1952–1970 K and XL Sportster models, along with earlier Flathead engines. Stock comes from names such as MCS and S&S Cycle, giving you reliable replacements for worn or stripped originals. A fresh timer drive gear is essential when rebuilding the timing chest on a Knucklehead, Panhead or early Shovelhead, keeping your Harley-Davidson sparking right on time. Browse the full range below.
