Additional Models Now Factory Equipped with Litens’ OAD Decouplers

Dozens of the latest vehicle models from domestic and import manufacturers are now factory equipped with overrunning alternator decouplers (OAD). The rapidly growing popularity of this sophisticated technology – now featured on more than 60 popular applications – is changing the way parts providers and repair professionals specify alternators, belts and pulleys for replacement applications. Overrunning alternator decouplers (also referred to as isolating decoupler pulleys, or IDP) help enhance engine efficiency and reduce noise, vibration and harshness. Using any other pulley technology, such as a one-way clutch, isolating pulley or solid pulley, on an OAD application can lead to a customer complaint and additional repair requirements.
