• Direct replacement style for select BMW alternator pulley applications

Product Details

This Continental alternator clutch pulley, part number 49722, is designed for BMW vehicles that use a grooved, flanged 6-groove pulley. The steel pulley body and internal clutch design work together to smooth alternator load changes, reduce belt flutter, and limit noise caused by rapid tension spikes. It is a practical replacement for BMW 128i, 135i, 328i, 528i, X3, X5, Z4, and related models listed in the fitment data.

This part cross-references Gates 37021P for the same application.
