Ohlins 17-20 Audi A4, S4, A5, S5 (B9) FWD/quattro; RS4, RS5 (B9), Rear Replacement Damper

This is the Ohlins rear replacement damper, part number AUS 6U00, designed for 2017-2020 Audi A4, S4, A5, S5 (B9) models, including both FWD and quattro variants, as well as the RS4 and RS5 (B9) models. If you're looking to restore or enhance the rear suspension performance of your B9 Audi, this damper is a solid option. Ohlins is well-known for its high-performance suspension components, and this rear damper is built to their exacting standards.

The AUS 6U00 damper features a monotube design, which helps maintain consistent damping performance by keeping the oil and gas separated. This construction is key to preventing aeration and fade, especially during spirited driving or when carrying extra weight. The damper body is made from aluminum, which helps keep the overall weight down while still offering good durability. It's designed as a direct replacement for your original rear damper, meaning it should fit right into the factory mounting points without requiring modifications. This makes installation more straightforward, allowing you to get back on the road with improved handling and ride comfort.

When installing this rear damper, it's always a good idea to inspect the surrounding suspension components, such as bushings and mounts, to ensure they are in good condition. Replacing worn components at the same time can help you get the most out of your new Ohlins damper and ensure optimal suspension performance. Refer to the manufacturer's installation instructions for specific details and torque specifications.
