911024 Throw out bearing kit, Heavy-Duty

This heavy-duty clutch throw-out bearing kit is a necessary upgrade for late 1975 to 1986 4 and 5-speed Big Twin models. Unlike the standard replacement, this heavy-duty version features more rollers within the assembly to distribute the load more effectively, leading to better reliability and a much longer service life under high-stress conditions. It is designed to replace OEM 37312-75 perfectly. Just keep in mind that this kit will not fit 1987 and later Big Twins because the larger outside diameter of the heavy-duty bearing causes clearance issues in those later primary setups. It is sold as a kit and is a smart choice for anyone rebuilding an early Evo or late Shovelhead clutch.
