Selecting the correct air pressure is critical for optimal performance and safety. Start with 5-10 PSI for unladen daily driving to maintain factory ride comfort. Increase pressure progressively as you add load — typical towing applications require 40-60 PSI, while maximum loads may need 80-100 PSI. Always adjust air pressure based on your current load and measure ride height to ensure the vehicle sits level. Never exceed the maximum 100 PSI rating stamped on the airbag assembly. Common loads affecting pressure requirements include: canopy and drawers (10-20 PSI), roof-top tent and awning (15-25 PSI), rear bar and dual spare wheels (20-30 PSI), caravan towing 2000-3000kg (50-80 PSI), and slide-on campers or heavy tradie payloads (70-100 PSI).
This Airbag Man kit is classified as Easy Fit and can be installed by experienced DIY mechanics with basic hand tools in approximately 2 hours. Professional installation is recommended if you're unfamiliar with suspension work or don't have access to a hoist and quality jack stands. The kit includes comprehensive step-by-step instructions accessible via QR code, with detailed photos showing exact mounting locations and torque specifications for the D22 platform. No wheel alignment is required after fitment as this is a helper spring system that doesn't alter suspension geometry. For complete suspension upgrades, consider pairing this kit with upgraded control arms and heavy-duty shock absorbers to maximize load-carrying capability and off-road performance.

This air suspension helper kit is perfect for Nissan Navara D22 owners who regularly tow caravans, boats or work trailers, carry heavy payloads in the tray, or need the flexibility to adjust suspension for varying loads throughout the week. It's equally suited to tradies hauling tools and materials Monday to Friday, then hitching up the van for weekend touring, as the airbags can be deflated for comfortable unladen driving. If you're experiencing rear squat, bottoming out over bumps when loaded, or poor headlight aim when towing, airbag suspension provides the most versatile and cost-effective solution without the harshness of static heavy-duty springs.

This kit is specifically engineered to fit all Nissan Navara D22 4x4 models manufactured from March 1997 through to 2015. It's designed as a universal rear fitment for both single cab and dual cab variants with factory leaf spring rear suspension. The kit will not fit Navara D21 (earlier model) or D40/NP300 (later models) as they have different chassis and suspension configurations. If you've modified your D22 with aftermarket leaf springs or suspension lifts, this kit will still fit as it mounts to the chassis rails and works with any leaf spring setup.
The Airbag Man kit is designed to assist your existing leaf springs with up to 2000kg of rear axle load support when inflated to maximum pressure. This doesn't increase your vehicle's legal GVM rating — you must still operate within Nissan's specified payload and towing limits. The airbags work progressively, meaning you can run low pressure (5-20 PSI) for light loads and increase up to 100 PSI for maximum support when towing heavy caravans or carrying full payload. The variable pressure adjustment is the key advantage over fixed-rate helper springs, allowing you to match support precisely to your current load.
This is a comprehensive Easy Fit Kit including everything needed for installation: two heavy-duty Firestone air spring assemblies, complete mounting bracket hardware, nylon air lines with push-to-connect fittings, two Schrader inflation valves, all mounting bolts and U-bolts, airbag protection sleeves, and detailed fitting instructions with QR code access. You'll need basic hand tools (spanners, sockets, jack and stands) but no welding or drilling is required. The kit does not include an air compressor — inflation valves are positioned for easy access with a portable compressor or service station air line. Optional in-cab inflation systems with onboard compressors are available separately if you want to adjust pressure on-the-go.
Yes, this is one of the most popular applications for the Airbag Man kit on Navara D22s. The adjustable air pressure eliminates rear squat and keeps your vehicle level when towing, which improves steering control, reduces trailer sway, maintains correct headlight aim, and prevents the rear suspension bottoming out on corrugations or dips. For typical caravan weights (2000-3000kg), you'll run approximately 50-80 PSI depending on ball weight and load distribution. The ability to deflate the airbags when you're not towing means you maintain comfortable daily driving without the harsh ride of permanently stiff helper springs.
No, control arm upgrades are not required when installing this airbag helper kit, as it doesn't alter your suspension geometry or lift height — it simply provides additional load support to your existing leaf springs. However, if your D22 is used for heavy towing or off-road work, upgraded control arms with heavy-duty bushings can improve handling and durability as part of a complete suspension system. Control arm upgrades become more important if you're also installing a suspension lift kit or experiencing worn bushings in the factory arms. Our team can assess your specific needs and recommend complementary upgrades if beneficial for your application.
No, wheel alignment is not required after installing this Airbag Man helper kit because it doesn't change your vehicle's suspension geometry, ride height (when properly adjusted), or steering angles. The airbags mount between the chassis and existing leaf springs as load-assist devices only. However, it's always good practice to have your alignment checked if you notice uneven tyre wear or if your vehicle hasn't been aligned in over 12 months. If you're installing this kit as part of a larger suspension upgrade that includes lift components or new control arms, then wheel alignment becomes mandatory.
Yes, infinite adjustability is the primary advantage of air suspension over fixed-rate springs. You can run as low as 5 PSI for comfortable unladen driving, then increase pressure in 5-10 PSI increments as you add load. Most users keep a portable air compressor in the vehicle and adjust pressure to match their current load — it takes just a few minutes using the accessible Schrader valves. For example, run 10 PSI for daily commuting, 30 PSI when carrying camping gear, 60 PSI when towing a boat trailer, and 80-100 PSI when towing a heavy caravan. Always adjust to achieve level ride height and never exceed the maximum 100 PSI rating.
This airbag kit doesn't provide suspension lift — it's a load-leveling helper system that maintains your factory ride height when properly inflated to match your load. If your vehicle currently sits at factory height, tyre clearance will remain unchanged. However, if your D22 is currently sagging under constant heavy loads, installing airbags and inflating them to restore level ride height may provide slightly more clearance than your current sagging position. For genuine increased tyre clearance, you'll need a proper suspension lift kit with raised springs or coils. The airbag kit can be used alongside lift kits to provide both increased height and adjustable load support.
This Airbag Man kit is covered by the manufacturer's comprehensive warranty against defects in materials and workmanship. Airbag Man has been supporting their products with reliable warranty service for over 25 years in Australia, with local spare parts availability and responsive customer support. Warranty coverage requires installation according to the provided instructions and operation within the specified pressure limits (maximum 100 PSI). Keep your proof of purchase and installation records for warranty claims. For specific warranty terms and duration, refer to the documentation included with your kit or contact our team for detailed warranty information.
Absolutely — daily drivability is one of the key advantages of adjustable air suspension over fixed heavy-duty springs. When you're driving unladen or lightly loaded, simply reduce air pressure to 5-10 PSI and the airbags provide minimal interference, allowing your factory leaf springs to deliver comfortable ride quality similar to stock. When you need load support for work or towing, increase pressure accordingly. This flexibility makes the system perfect for tradies who carry heavy loads during the week but want comfort for family duties on weekends, or tourers who tow occasionally but don't want a permanently harsh ride when solo driving.
Best upgrade I've done to the Navara
Chucked these airbag helpers on my D22 after getting sick of the back end sagging every time I loaded up tools and materials for site work. Made a massive difference to how level it sits now, and the ride quality is heaps better even when I'm running empty. Installation was pretty straightforward too, and they've held up well on some rough tracks out bush on weekends.(5)
Perfect Upgrade for Our Family D22
Been running this Airbag Man kit on our D22 for six months now and it's made a massive difference when we load up the camper trailer and gear for weekend trips. The rear end sits level even with the kids' bikes, firewood, and all our camping equipment loaded up. Installation was straightforward enough to tackle in the driveway, and the adjustability means I can fine-tune it depending on what we're carrying. Genuinely wish I'd fitted these air suspension helpers years ago.(5)
