The KONI Special Active (FSD) rear shock is a direct-fit replacement for rear‑drive BMW 3‑Series (E46) models from 1999–2005, restoring controlled damping and ride comfort. It uses a twin‑tube hydraulic, low‑pressure gas design and is non‑adjustable, offering a durable, OEM‑friendly upgrade that balances everyday comfort with improved rear damping without requiring valve or mounting changes.
