Upgrade your performance sedan with Function and Form’s s4 b6 air suspension, engineered for the 2003–2005 Audi S4 4WD B6/8E chassis. Developed using our advanced Type 5 suspension platform, this system provides complete ride height adjustability, letting you go low for an aggressive stance or raise the car for everyday drivability. Whether your S4 is a daily driver, weekend toy, or show build, this suspension gives you the versatility you need without compromise.

The Audi S4 B6 is admired for its 4.2L V8 powerplant, Quattro all-wheel-drive system, and luxury refinement. However, the stock suspension setup doesn’t provide the adaptability that modern enthusiasts expect. Lowering springs and coilovers may improve the stance, but they lock you into a fixed ride height, often sacrificing comfort and practicality. Function and Form’s Type 5 system addresses this issue by giving you the freedom to lower your car for shows or raise it to handle speed bumps, steep driveways, and uneven roads. This makes s4 b6 air suspension the perfect solution for those who want aggressive styling and everyday usability in one package.

Each suspension unit is built with heavy-duty double-bellow air bags, designed to balance strength, comfort, and reliability. Precision-machined mounts provide a direct bolt-on installation for the B6 chassis, while corrosion-resistant finishes ensure long-term durability even in harsh conditions. Built to handle spirited driving and daily use alike, this suspension system is designed to deliver consistent performance while maintaining Audi’s reputation for refinement.

Pairing the Type 5 suspension with air management systems like Air Lift 3P or 3H unlocks the system’s full potential. With these, you can save custom ride height presets, monitor air pressures in real time, and adjust your suspension instantly using a wired controller or smartphone app. Add a VIAIR compressor and polished tank for a complete air ride setup that combines practicality with premium presentation.
