Jims Sprocket Shafts

8 products — part of all Sprocket Shafts

Jims sprocket shafts for Harley-Davidson are precision-manufactured to the dimensional tolerances that the primary drive demands — the critical engine output shafts that connect crankshaft rotation to the primary chain or belt. A worn or incorrectly dimensioned sprocket shaft introduces misalignment and runout that accelerates primary chain or belt wear and puts stress on the inner primary bearing. Jims applies the same toolroom-quality manufacturing that defines their engine tools programme to their Harley-Davidson sprocket shafts, ensuring correct journal diameters, thread forms and surface finishes for accurate bearing fit and reliable seal retention. Fitting a Jims sprocket shaft during an engine rebuild is the professional approach to preventing repeated primary drive failures. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks Jims sprocket shafts. Browse the full Jims Sprocket Shafts range below.
