Product details
Basic air suspension keeps the BMW 3 Series hardware simple. Model years and chassis vary across the 3 Series, so confirm yours before ordering. The controls are manual: paddle valves plus a dual-needle 200 psi gauge, so you set pressure by eye.
Kit contents include four application-specific air struts with 36-way damping, a Viair 444C compressor, a 5-gallon black steel tank, hoses, wiring, installation manuals and a damping knob. The compressor is described as chosen for reliability and performance. A stated height range of 0 to 120/200 mm depending on vehicle shows how much adjustment the air spring offers, and the lower mounts allow fine-tuning at any pressure.
Other listed fitments include the 1 Series (E82/E88, including 128i, 135i, 135is and cabrio) and E90/91 3 Series sedans from 325i to 335is. Ask a technician whether camber-adjustable top mounts apply to your car. Use the year, make and model checker to confirm fitment, and plan on professional installation.
Supported features
36 levels of damping adjustment let you dial in the air struts. Insert the included damping knob and turn softer (counterclockwise) or stiffer (clockwise).
Air bags are engineered to match the vehicle. Sleeve-type and double-bellow bags are used depending on the OEM suspension design.
Like KSport coilovers, the struts allow fine-tuning of ride height at any pressure through an adjustable lower mount.
Chosen for reliability and performance; the single 444C can raise the car from lowest to maximum height in as little as four seconds. Airtech Basic and Deluxe raise in 4–7 seconds; Pro Plus and Executive raise faster, in 2–5 seconds.
Paddle valves control front and rear bags; the dual-needle gauge mounts beside the switches so pressure is always visible.
Camber-adjustable top mounts can be added on certain MacPherson-strut applications.
