INA EA0168 Overrunning Alternator Decoupler Pulley

The INA EA0168 is a precision-engineered overrunning alternator pulley (OAP), also known as an alternator decoupler pulley, designed to optimize alternator performance and extend the service life of your vehicle's accessory drive system. This OEM-quality replacement component features advanced decoupling technology that reduces noise, vibration, and harshness throughout the engine bay.

Key Features:

• Overrunning design with integrated torsion spring dampens vibrations and isolates the alternator from crankshaft fluctuations
