Bilstein B4 OE Replacement DampTronic Rear Shock Absorber - Audi S6 2020-2025

The B4 OE Replacement DampTronic is a direct replacement for the electronically adjustable damper Audi fits from the factory, built to accept the original damping signal so the car's adaptive suspension modes keep working exactly as delivered. Bilstein valves it to restore the original ride quality and body control rather than change the car's character, and manufactures it to meet or exceed the OE specification. High power reserve in the damper is what holds that behaviour under load, which is the practical difference between an OE grade replacement and a budget one. Ride height and spring rates are untouched.
