Why air on this car
The Nissan Skyline R34 was built as a driver’s car first, and the market has treated it that way ever since: prices reflect an enthusiast who cares about corner weights and ride height as much as looks. Left on standard springs or dropped on fixed coilovers, most examples either sit too high for the arch fill owners want or too low to clear a typical UK driveway or speed hump without drama.
Air suspension sidesteps that argument. Run it low for photos or a track day paddock, lift it for the school run, a ferry ramp, or a pothole-scarred B-road, and return to your preferred setting each time. Given the R34’s age and rarity now, the ability to raise the car away from kerbs and rutted car parks on demand matters more than it once did.
Both front and rear use pillowball top mounts here, so steering and rear-end response stay sharp and direct, with a bit more road noise than the standard rubber bushes. Struts and Bags suits owners running their own management; the higher tiers move towards sensor-based height control and repeatable presets.
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
- Contents
- Struts × 4 with air bags; no management
- Damping adjustment
- 36 levels, all four struts
- Top mount (standard)
- Rubber on McPherson struts; pillowball optional for camber adjustment
- Fitting
- Bolt-on; original dampers not reused
- Drive
- Applications are 2WD unless 4WD is stated
Universal
The entry kit. Four 36-way adjustable struts with air bags, a 20-litre tank, compressor and a pair of mechanical switches with a dual-needle gauge on a bracket. You raise and lower the car by hand from the cabin, reading pressure off the gauge. Bolts on with no cutting or welding.

Super Performance
Super Performance moves to eight solenoid valves and pressure sensors on all four bags and the tank. Each corner can be set separately, and the AFH memory remote shows every pressure on screen and holds four saved heights. No cabin gauge or switches are needed, and the faster valves cut a full height change to two to five seconds.
Who it suits: Drivers who want corner-by-corner pressure control and saved heights, with a damping tune aimed at handling.

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.
- Variant: rear fork-mount strut.
- Application note: Rr FORK.
- Listed by the factory as: SKYLINE R34 (Rr FORK).
- 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.
Going struts and bags only?
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.
