The manufacturer quotes around three hours for Luxury and around two for Super Performance and Gold, on the basis that the kit bolts on with no cutting or welding. Allow longer for a first fit, for routing the lines and mounting the tank and compressor neatly, and for the clearance check at full height.

Air suspension is not itself an MOT failure. The tester checks the condition and security of the suspension, that nothing fouls, and that headlamp aim and ride height are sensible at the time of test. Raise the car to a normal driving height before the test and make sure the system holds pressure.

That is largely up to you. The struts have 36 levels of damping adjustment, so you can set them soft for the motorway or firm for a quick road. Air bags change stiffness with pressure too, so ride height and ride quality are linked; most owners settle on a daily height and leave it there.

The system lives under the car like any other suspension, so salt and grit are the enemy of fittings and linkages rather than the bags. Keep the tank drained of moisture, check the air lines and connections when you change to winter tyres, and rinse the underside after salted roads.

Struts are covered against oil leaks for five years, provided they come back for service every two years. Compressors, bags and electronics have their own manufacturer terms, and your UK statutory rights sit alongside all of it. See our warranty page for the detail.

On Super Performance, Gold and Diamond you set the car to a height, hold a memory button for two seconds, and the remote stores it. Press the button later and the car returns to that height. There are four memories, the fourth reserved for your lowest setting, and key-on recall can send the car to a chosen preset when you start it.

Yes, the kits are designed as road suspension. Gold and Diamond are the easiest to live with because the height sensors hold a measured ride height whatever the load, so a boot full of shopping or four passengers does not change where the car sits.

You will hear it run when the tank tops up. The kits include a silencer plate base and, from Super Performance up, a vibration-free mounting socket to keep that down. The RC controllers let you pick the pressures it switches on and off at, so it runs in short bursts rather than constantly.

If you want switches and a gauge, Universal. If you want a remote, Luxury. If you want each corner controlled separately with saved heights, Super Performance. If you want the car to hold an exact height regardless of load, Gold. If you also want nitrogen reservoir struts with separate compression and rebound, Diamond. Our comparison table sets it out side by side.

Kits are built to order and shipped direct from the factory, typically around 21 working days from the date of purchase. We confirm the lead time for your specific kit and top mount choice before you pay, and we will tell you if the factory is closed or a part is on back order.
