Why air on this car
The Nissan Dayz B21W is one of the tall, narrow kei cars that have found a following in the UK as personal imports, prized for a footprint smaller than anything built for this market and a boxy shape that leaves plenty of headroom. That height means the standard ride sits high over small wheels, so even a modest drop changes the car’s proportions more than on a wider, lower design.
Because the Dayz is so light, the compressor and tank take up little of what is already a small load area. Air suspension lets you run it low for a meet, then lift it for speed bumps, a steep driveway or an uneven car park before dropping it back down. The front struts use a rubber top mount, so ride comfort stays close to standard, and the rear keeps its original mount. Struts and Bags suits an owner sourcing their own management; the kits above it trade a little simplicity for smoother, more consistent height control.
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

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.

Luxury
Luxury takes the Universal hardware and adds a Deluxe control box with four solenoid valves and a wireless remote. You can raise, lower or stop the car at any height from inside or outside it. The switches and gauge are still supplied. Typically fitted in about three hours.

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.
- Eight solenoid valves; each corner adjusts independently
- Pressure sensors on all four bags and the tank
- AFH memory remote with four saved heights, plus a simple remote
- Low tank pressure warning and key-on height recall

Fitment notes
- Front top mount: Rubber top mount. The standard fitment on McPherson-strut cars. Rubber isolates the body from the strut for the quietest ride, at the cost of a little precision. Camber is not adjustable on this mount.
- 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.
- Stock check needed: this application is built to order and availability must be confirmed with the factory before we take payment. We will confirm by email before charging you.
- 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.
