Modernize your sedan’s stance and drivability with Function and Form’s A4 B9 air suspension, designed for the 2016+ Audi A4 2WD B9/8W chassis. Built on our proven Type 5 air strut platform, this system gives you the freedom to fine-tune ride height on demand while maintaining the balance of comfort, performance, and style. Whether you daily your Audi, attend car shows, or enjoy spirited drives, these struts adapt instantly to every situation.

The Audi A4 B9 is one of the most refined versions of the model, combining advanced technology, sharp styling, and everyday practicality. However, factory suspension systems lack the flexibility today’s enthusiasts want. Traditional coilovers or lowering springs improve stance but sacrifice ride quality and adaptability. With Function and Form’s Type 5 struts, you can drop your A4 low for a show-ready look or raise it back up for practical clearance on steep driveways, speed bumps, and rougher roads. This versatility makes A4 B9 air suspension the perfect upgrade for owners who want aggressive style without giving up everyday usability.

Each strut features a double-bellow air bag engineered to provide strength, load capacity, and comfort. Precision-machined mounts guarantee a direct bolt-on fit for the B9/8W chassis, while corrosion-resistant finishes extend long-term durability against weather and road conditions. This suspension system is designed for both daily use and performance builds, offering reliability and adaptability in one package.

For full integration, the struts are compatible with leading air management controllers such as Air Lift 3P and 3H. These systems let you save ride height presets, monitor pressures, and make real-time adjustments through a wired controller or mobile app. Pairing your struts with a VIAIR compressor and polished air tank completes your build with a setup that looks as good as it performs.
