Why air on this car

The Lexus GS 350 4WD is a substantial executive saloon, built for quiet motorway miles rather than backroad theatre, and its standard ride height leaves a fair gap between arch and tyre that few owners bother to address. Lowering it on fixed coilovers usually means trading away the comfort the car was designed around, which defeats the point of owning one.

Air suspension keeps that trade-off in your hands instead. Drop the GS for a smarter, tucked-in stance when it is parked, raise it again for a steep multi-storey ramp or a pot-holed side road, and settle on a driving height that still soaks up motorway expansion joints the way a big Lexus should. All-wheel drive adds weight over the axles, and the air spring copes with that load more evenly than a compressed steel coil at the same ride height.

Both front and rear use a pillowball top mount, a solid spherical bearing that sharpens steering response at the cost of a touch more road noise. Lower tiers keep things simple and affordable; the higher tiers add corner-by-corner and height-sensing control for a car that spends most of its life at a fixed, comfortable setting.

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.

  • Four vehicle-specific struts and four air bags
  • 36 levels of damping adjustment
  • No tank, compressor, valves, remote or wiring included
  • For existing management or separately chosen RC1/RC2
  • Bolt-on fit, no cutting or welding
  • Rubber top mount standard; pillowball optional

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: 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.
  • Application note: S190.
  • Listed by the factory as: GS 350 4WD (S190).
  • 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.
