Transmission Mount Plates for Harley-Davidson provide a solid mounting platform between your gearbox and the frame, essential for custom builds and hardtail conversions where the original mounting points may differ. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks transmission mount plates from MCS, Paughco and Ost Freesen Choppers for Big Twin and Sportster applications. Whether you are fitting a four-speed into a custom rigid frame or adapting a five-speed to a different chassis, these plates are precision-cut to ensure correct alignment with the primary drive and engine. A properly fitted mount plate eliminates drivetrain stress and extends component life. Browse the full range below.
