The Audi A4 B9 is a worthy challenger to the other luxury sedans, with some reviewers even giving it the edge over its rivals. Featuring a quiet interior, where almost no engine noise is noticeable, the A4 is even more luxurious than ever. It's built to be economical and easy to handle over long drives, but where's the sporty drive that you expect from an Audi? That's where Air Lift Performance is here to help. In order to give you that missing performance, our engineers built a rear kit featuring our double-bellow air springs, which provides the ability to air out 161mm from stock. The threaded-body dampers feature 30 levels of adjustability, creating an air suspension that is completely customizable for your ideal performance setup. As the leader in air suspension products for more than 70 years, Air Lift Company and its Performance division shows its commitment to delivering quality parts that last by torture-testing all of the major kit components on our in-house validation equipment. With a one-year, unlimited-mileage warranty -- not to mention the Air Lift Performance reputation for great customer service and technical support -- you can purchase this kit with peace of mind.
