Eibach 05-11 Audi A6 Quattro C6 6 Cyl. Single Rear Spring

This is a single rear spring from Eibach, specifically made for the 2005-2011 Audi A6 Quattro with a 6-cylinder engine. When you need to replace a rear spring, especially if one side has sagged, getting a matched pair ensures your car sits level and handles predictably. Eibach uses carefully selected spring steels, wound on advanced CNC machines for accuracy. They're heat-treated, shot-peened, and finished with a durable powder coating to resist corrosion and maintain stability over time. This process helps ensure the spring sets to the correct ride height and stays there, so your Audi maintains its intended stance and handling characteristics for many miles.
