The KONI Special Active Shock FSD is a front twin-tube hydraulic, low-pressure gas McPherson strut made for 2012–2017 BMW 2, 3 and 4 Series RWD applications with M‑Technik front suspension. This non-adjustable replacement strut uses KONI’s twin‑tube low‑pressure gas design to manage front damping in McPherson layouts. It is supplied as a direct replacement intended to restore proper front suspension function without manual adjustment.
