Sensor‑Driven Air Bag Suspension for BMW X5 E70 2008 onward

Give your BMW X5 E70 the stance, comfort and control it deserves with the latest AirRex V2 sensor‑referenced air bag system. Designed for vehicles with the factory coil‑spring and strut layout, this premium conversion swaps bulky stock components for direct‑fit pneumatic struts, delivering show‑car lows, effortless everyday usability and precise ride‑height repeatability. Enjoy wireless control via smartphone and the included touchscreen handset, with Wi‑Fi connectivity for fast, reliable adjustments.

Built for people who demand accuracy, comfort and reliability

• Height sensors at each corner read true suspension position, so your chosen ride height returns exactly the same every time.
• App control for iOS and Android plus a wireless touchscreen handset keep adjustments simple, quick and intuitive.
• Auto lift on start‑up raises the SUV to your preset driving height the moment you fire the engine.
• Direct‑fit assemblies use the factory mounting locations for a tidy, confidence‑inspiring install.
• Air springs are load tested and paired with correctly valved monotube shocks for composed handling and a refined ride.
• Validated in extreme climates from -40°C to +60°C for dependable performance year round.

Performance struts engineered for the E70 platform

AirRex struts are tuned for everyday road use and weekend show duty, with hardware that stands up to real‑world driving.

• Front: 12‑click damping adjustability, threaded bodies for height range, camber‑adjustable top mounts where chassis allows, and robust bellow air springs. Applications utilise double or triple bellows where higher load capacity is required.
• Rear: 12‑click damping adjustability, threaded bodies and compact bellow springs. Slim double bellows are used where space is tight, moving away from sleeve‑type bags.

Advanced management you can trust

The AirRex control system integrates seamlessly with the ride‑height sensors, giving you fast, smooth changes and stable levelling. The wireless touchscreen controller and smartphone app make it effortless to switch between your saved presets, raise for speed bumps or lower for parking.
