The Airbag Man Air Suspension Helper Kit (CR5040) fits Nissan Patrol GQ, GU and GR models running factory coil springs, adding variable air support from 5 to 30 PSI to stop rear sag under load. It works inside your existing coil spring setup without swapping springs, so you keep standard unladen ride height and only firm things up when towing or loaded for touring. Dispatched from Australian stock with manufacturer warranty and fitment support from our team.
Airbag Man helper kits use coil-insert air springs that sit inside the existing coils – add air when the load goes on to bring the vehicle back level, then let it out and the standard springs carry on exactly as before. Because each side inflates independently, you can also correct for an off-centre load like a slide-on or water tank.
They shine when the load keeps changing – a van on the towball some weekends, a loaded tray on others. Worth being clear about what they don't do: helper airbags don't increase your GVM or payload; they manage ride height and stability within the vehicle's existing ratings. If the vehicle is always loaded, upgraded springs (with airbags for the variation on top) is the better setup.

This helper kit uses air pressure, not spring rate, to firm up the existing coil spring — set 5-10 PSI for light constant loads like a bullbar, winch and dual battery tray, and wind up toward 20-30 PSI when towing a van or carrying camper gear and water tanks. If your Patrol carries a heavy canopy, tray back or permanent GVM upgrade, a higher-rate replacement coil spring may suit better than air alone, so talk to our team about the right combination. Common accessories that shift the ideal setting include bullbars, winches, long-range fuel tanks, drawer systems, camper trailers and caravans.
Fitting the CR5040 kit means compressing the factory coil spring to insert the air bag, so it's best handled by an experienced installer or a competent home mechanic with spring compressors on hand. Wheel alignment isn't required from this kit alone since ride height doesn't change, but it's worth checking alignment if you've recently fitted other suspension components. Run the system in for around 500km at a low starting pressure to confirm the air line fittings and valve are holding pressure correctly. These vehicles use a solid front axle on coil springs, located by radius arms and a panhard rod rather than IFS control arms, so geometry correction at lift height comes from caster-correction radius arm bushes or adjustable radius arms plus an adjustable panhard rod.
Airbag Man has been designing and testing air suspension products for Australian 4WDs and utes for over 25 years, with kits developed around local touring and towing conditions rather than adapted from overseas parts. Every CR5040 kit is backed by a manufacturer warranty and dispatched from local stock, with fitment support from our team if you're unsure about your Patrol's coil spring configuration. Tourers and tradespeople running Patrols with a constant rear load rely on Airbag Man kits to keep sag in check without a full spring or lift kit swap — view the full Airbag Man range for other Patrol options.
This kit suits Patrol owners who load up for touring — camper trailers, rooftop tents, long-range fuel and water — and want to firm up the rear only when it's loaded. It's also a straightforward fix for tradespeople carrying tools, a compressor or canopy load on the tray daily. If you're after a permanent lift rather than adjustable load support, browse our airbag suspension range alongside our coil and leaf spring options to find the right combination for your Patrol.

Genuine Airbag Man suspension from an authorised Australian dealer.
The CR5040 fits Nissan Patrol GQ, GU and GR models that run factory coil springs on the rear axle. It's designed to sit inside the existing coil spring, so the fitment depends on your Patrol having coil rear suspension rather than leaf springs. If you're not sure which rear suspension your Patrol has, our team can confirm it from your build details before you order.
This kit doesn't add lift — it's a load-levelling helper that firms up your existing coil spring under load. Air pressure is adjustable from 5 to 30 PSI, and at low pressure the ride height and feel stay the same as your standard unladen setup. If you want a raised ride height as well, that's a separate lift kit with taller coil springs, which our team can help you match.
The CR5040 includes 2 x Airbag Man air helper springs that fit inside the factory rear coil springs, an inflation valve kit with braided air line, mounting hardware and fittings, plus fitting instructions. A 12V compressor or foot pump for adjusting pressure is not included. Everything needed to install the air bags into your existing rear coil springs is in the box.
Yes, this is a common use for the CR5040. Winding the air pressure up toward 20-30 PSI firms the rear coil spring to counter the ball weight of a van or trailer and stop rear sag. You can then deflate back down for unladen driving once the trailer is unhitched.
This vehicle runs a solid front axle on coil springs, located by radius arms and a panhard rod, so there are no upper or lower control arms to upgrade like an IFS vehicle. At around 2" of lift most vehicles run the kit as supplied; taller lifts benefit from caster correction (offset radius arm bushes or adjustable radius arms) to restore steering self-centring, plus an adjustable panhard rod to re-centre the axle. Our team can advise what your lift height and build need.
Not specifically because of this kit, since it doesn't alter ride height or suspension geometry. It's still good practice to check alignment if you've had other suspension work done around the same time. If your Patrol is due for a service or has had other components changed recently, get the alignment checked while it's in.
This kit adjusts air pressure rather than spring rate, giving you a 5-30 PSI range to match the load rather than a fixed spring rate choice. If your Patrol carries a heavy canopy or accessories permanently, a higher-rate replacement coil spring alongside or instead of this kit may suit better. Our team can talk through your accessory load and recommend the right combination.
This kit doesn't raise ride height, so it won't change tyre clearance under the guards. If you're planning to fit larger tyres, you'll need a genuine lift kit with taller coil springs rather than this load-levelling helper kit. Our team can advise on a suitable Patrol lift kit to suit your tyre size.
The CR5040 is backed by Airbag Man's manufacturer warranty, covering faults in the air bag bladder, valve and fittings under normal use. It's dispatched from our Australian stock, and our team can help with any warranty query or fitment question after purchase. Keep your purchase details on hand for any warranty claim.
Yes. At low pressure (around 5 PSI) the kit sits passive and shouldn't be noticeable in daily unladen driving, since it's only firming the coil spring when you increase pressure for a load. Many owners run it deflated day-to-day and wind it up only when towing or loaded for a trip. It's a practical option if your Patrol goes between empty commuting and loaded touring or towing.
