AST Suspension Lowering Springs (30mm/30mm TUV) - 2004-2011 Audi A6 Quattro 4.2/2.7TDi/3.0TDi (4F)

The AST Suspension Lowering Springs for the 2004-2011 Audi A6 Quattro (4F) are high-performance suspension components designed to reduce ride height and improve handling. Crafted from premium high tensile chromium-silicone wire, these springs are engineered for durability and consistent performance. Each spring undergoes a meticulous manufacturing process, including cold winding, heat treatment to enhance hardness, and shot peening to relieve internal stresses. The springs are then phosphate treated and powder coated, ensuring long-lasting corrosion resistance and aesthetic appeal. Featuring progressive rates on most vehicles, these springs provide a balanced ride quality, combining comfort with enhanced stability during aggressive driving or cornering.

Designed specifically for 2004-2011 Audi A6 models equipped with the 4.2L V8, 2.7TDi, or 3.0TDi engines, these springs serve as a direct replacement for factory components. They are compatible with vehicles featuring Electronic Damping Control (EDC), allowing for seamless integration with existing suspension systems. Ideal for street performance and daily driving, the springs lower the vehicle by approximately 30mm at the front and rear, improving stance and handling without sacrificing ride comfort. Installation is straightforward for those familiar with suspension work, and the kit includes the springs necessary for a complete upgrade. These springs are suited for enthusiasts seeking improved aesthetics and performance in their Audi A6.
