We run AirREX on our own cars and our customers consistently praise the comfort, control and dial‑a‑stance flexibility. If you are searching for a bagged BMW 5 Series solution, an adjustable air bag conversion, or a premium alternative to coilovers for the G30 or G38, this is the setup enthusiasts choose.

Height‑referenced management for repeatable ride height

V2 management uses external ride height sensors to read suspension position, so your presets stay consistent regardless of passengers, fuel or luggage. Set it once and enjoy accurate results on motorways, B‑roads and show grounds. Full control is available via the mobile app and the wireless touch screen remote, including auto lift at start‑up for daily use.

Performance air struts with plug‑and‑play fitment

The strut assemblies are a direct replacement for the factory units, giving you a clean bolt‑on install with OEM mounting points. Each air spring is pressure‑tested and paired with correctly valved mono‑tube dampers for the ideal balance of comfort and control. Components are validated through extreme temperature testing from -40°C to +60°C for year‑round dependability.

Air springs and damper specification

• Front: 12‑stage damping adjustable mono‑tube dampers, height adjustable bodies, bellows air bags and camber top mounts where the chassis allows. Applications use double or triple bellows depending on required load capacity.
• Rear: 12‑stage damping adjustable mono‑tube dampers, height adjustable bodies and bellows air bags. In tight spaces, newly developed slim double bellows are used instead of sleeve bags.

This configuration is built to handle changing UK road surfaces and gives you the flexibility to run low at shows and comfortable on the daily drive.

Air management and control

The AirREX control system delivers smooth, accurate and reliable operation. The wireless touch screen remote communicates via WiFi, and the system is fully app‑enabled for iOS and Android so you can store presets, adjust heights and fine tune settings with ease.
