Jims Rocker Arm Parts

5 products — part of all Rocker Arm Parts

Jims rocker arm parts go to the tight-tolerance end of the valvetrain rebuild — the bushings, roller bearings, and shaft components that determine how much side-play your rockers carry after ten years and 50,000 miles on a hard-used Harley-Davidson V-twin. Fitment spans 1966–2017 Big Twin excluding Milwaukee-Eight, 1986–2022 XL Sportster, 1966–1984 Shovelhead, the XR1200, and 1991–2010 Buell XB. Jims' machining tolerances on engine internals are tighter than generic replacements — this is the same workshop that makes the go-to special tools for Harley-Davidson engine and transmission work, and the component quality reflects that same standard. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Jims rocker arm components for professional and amateur builders. Browse the full Jims Rocker Arm Parts range below.
