Description
The JIMS Sprocket Shaft is a critical drivetrain component that directly impacts torque delivery and chain longevity on your Big Twin. Factory shafts wear over time, leading to slack in the primary drive and accelerated sprocket degradation. This U.S.A.-manufactured replacement restores precise fitment and reduces wear across your entire drivetrain system.
Designed for 1981-1985 Big Twin models, this shaft is engineered to exacting tolerances to ensure smooth power transfer without play or binding. Installation is straightforward, making it an ideal upgrade for both rebuild projects and preventive maintenance on higher-mileage engines.
