Upgrade your Quattro sedan with Function and Form’s a4 b6 air suspension, designed for the 2001–2005 Audi A4 B6/8E chassis. Our Type 5 air struts provide complete ride height adjustability, giving you the ability to fine-tune stance, comfort, and performance all in one system. Whether your A4 is a daily driver, a weekend show car, or a performance build, these struts give you the adaptability and reliability you need.

The B6 Audi A4 has become a favorite among enthusiasts thanks to its timeless styling, balanced handling, and proven Quattro drivetrain. However, stock suspension setups offer little customization, while static lowering options like springs and coilovers compromise comfort and practicality. With Function and Form Type 5 air struts, you can instantly drop your A4 for an aggressive show stance or raise it to handle speed bumps, steep driveways, and rough roads. This versatility makes a4 b6 air suspension the perfect choice for owners who want both style and usability without compromise.

Each strut is engineered with a durable double-bellow air bag that balances strength with ride quality. Precision-machined mounts ensure a direct bolt-on installation for the B6/8E chassis, while a corrosion-resistant finish protects the struts from wear and harsh conditions. Designed for long-term reliability, this system is capable of handling daily use while offering the adjustability that makes air suspension so desirable.

The struts integrate seamlessly with modern air management systems such as Air Lift 3P and 3H. These controllers allow you to monitor pressures, save custom presets, and make adjustments in real time from either a controller or smartphone app. For a complete solution, pair your Type 5 struts with a VIAIR compressor and polished tank for both dependable operation and a professional finish.
