Please understand that this pulley damper is an OEM German part and IS NOT the inferior Chinese made product seen on many websites and eBay. Our customers have told us that the Chinese units are only good for a few months before falling apart. As with most things in life.....you get what you pay for. Our unit is a top quality OEM part.
This unit is manufactured by Corteco and they are the OEM supplier to Mercedes Benz.
Not for vehicles with accessory rear A/C having a 2nd A/C compressor, which is driven by a second belt, a V-belt. Those vehicles require a special two-belt pulley that is shown below.
