908094 Alternator rotor & sprocket assembly, 21A

This 21-amp alternator rotor and 35-tooth motor sprocket assembly is a significant upgrade for 1991 to 2003 Harley-Davidson Sportster models. One of the most common failures on these XL charging systems is the magnets working themselves loose from the rotor, which can cause catastrophic damage inside the primary. This MCS assembly solves that issue by encapsulating the magnets in a protective stainless steel shell, ensuring they stay exactly where they belong. It is designed to replace OEM part number 32413-92C and provides a reliable, long-term fix for your charging system. Whether you are performing a routine service or a full rebuild, this assembly offers better-than-factory peace of mind for your Evo Sporty.
