Why air on this car

The BMW X5 F15 4WD is a large, heavy SUV that carries a full load of people and luggage on suspension built to handle both comfort and weight. This kit fits X5s built with conventional struts from the factory, not ones already running air.

Lowering an X5 on fixed coilovers costs practicality: a steep driveway or multi-storey ramp catches the nose, and a loaded boot sags further with less give to spare. Air suspension avoids that, dropping for a tighter stance when parked and lifting for a rutted track, a kerb-heavy car park or a loaded motorway run.

The front struts use a pillowball top mount, giving sharper steering feel with a touch more road noise, while the rear keeps the original BMW mount. Choosing a tier is about how much automatic correction you want: simpler kits hold a set pressure, the top tiers add height sensors that return the car to its presets automatically.

What's in the kit

Struts and bags

Struts and bags is the air suspension hardware without any management: four vehicle-specific struts with 36 levels of damping adjustment and the air bags that go on them. Choose it if you already run management you want to keep, or you are buying the RC1 or RC2 controller and tank separately.

Who it suits: Owners keeping their existing management or choosing their own, who need only the struts and air bags.

  • No tank, compressor, valves, remote or wiring included
  • For existing management or separately chosen RC1/RC2

Fitment notes

  • Front top mount: Pillowball top mount. A spherical bearing replaces the rubber, giving the sharpest steering response and allowing camber to be adjusted at the top of the strut. Expect more noise and vibration than rubber.
  • Rear top mount: OE top mount. The kit reuses your car's original top mount rather than supplying a new one. Ride feel and camber stay as the factory set them.
  • Application note: NON AIR STRUT.
  • Listed by the factory as: X5 F15 4WD (NON AIR STRUT).
  • Built to order — the typical lead time is around 21 working days from the date of purchase to UK delivery. We confirm the lead time for your kit before you pay.

Five years against oil leaks, with a service every two years

AirForce covers its air suspension struts against oil leakage for five years. To keep that cover, the struts need to come back for inspection and maintenance every two years; the manufacturer treats the service as a condition of the warranty, so book it in and keep the paperwork.

Damage caused by suspension components rubbing against an inflated air bag is not covered, which is why we ask your fitter to cycle the system to full height and check clearances before they hand the car back.

Compressors, air bags and the electronic control box and remotes carry the manufacturer’s separate terms, and electronic parts may need to go back to the factory for repair. Ask us for the current wording before you order.

None of this affects your statutory rights as a UK consumer. If a product is faulty, your rights under the Consumer Rights Act 2015 apply alongside the manufacturer’s warranty, and your contract is with us as the retailer.
