Jims transmission components are engineered exclusively for Harley-Davidson V-twin gearboxes, with the precision tolerances that professional workshops have relied on for decades. Jim Thiessen built his brand on one principle — if a tool or component does not exist for a specific Harley-Davidson procedure, make it. That same philosophy drives the Jims transmission parts range, which covers gears, bearings, shift forks, mainshafts and complete rebuild kits machined to tighter tolerances than many OEM replacements. Their work on five-speed and six-speed Harley-Davidson transmissions spans Softail, Touring, Dyna and Twin Cam platforms, with each component designed for professional installation using Jims purpose-built service tools. The combination of matched tools and precision-machined parts means a Jims transmission rebuild goes together correctly the first time, without the guesswork that comes from mixing incompatible aftermarket components. It is the brand that Harley-Davidson specialists return to when the job has to be right. Available through Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, Jims gives UK mechanics access to American workshop-grade transmission expertise.
