A used Audi RS4 Timing Chain Gear / Sprocket (OEM 079109077A) from a genuine 4.2L V8. This gear meshes with the timing chain to synchronize cam and crank timing. Known as a timing chain sprocket, it’s a critical component in the RS4’s chain drive system. Wear can cause chain slack, leading to rattling noises on cold starts or potential timing drift. This used OEM part was removed from a running donor vehicle.
