- Litens Automotive is the original equipment supplier for this Mercedes-Benz and Infiniti application. This replacement alternator pulley is also designed and produced by Litens and is exact in all form, fit, and performance characteristics as the original equipment part.

The correct decoupler pulley ensures smooth, quiet performance as well as increasing vehicle gas mileage.
