The beauty of airbag suspension is infinite adjustability – simply add or release air pressure to suit your exact load. Start with 5-10 PSI for unladen driving to maintain factory ride comfort. Gradually increase pressure as you add payload: 20-40 PSI for moderate loads like camping gear and recovery equipment, 50-70 PSI for towing medium-weight trailers, and up to 100 PSI for maximum load capacity when towing heavy caravans or loaded trailers. Always adjust pressure to achieve level ride height front-to-rear, checking that your Patrol sits parallel to the ground. Common loads affecting rear suspension include roof racks, bull bars, dual battery systems, water tanks, camping equipment, toolboxes, fridge slides, drawer systems, spare tyres, jerrycans and tow ball weight from caravans or trailers.
This Airbag Man kit is classified as an Easy Fit Kit with an estimated installation time of approximately 120 minutes for experienced DIY mechanics with proper tools and vehicle jacks. Professional installation is recommended if you're unfamiliar with working under vehicles or suspension components. The kit includes comprehensive step-by-step instructions accessible via QR code, with clear diagrams showing mounting points and torque specifications. While wheel alignment is not typically required for airbag helper kit installation (as lift kits would require), it's worth checking alignment if your Patrol has covered significant kilometres. Allow a brief settling period after installation and check all fittings and mounting hardware after the first 100km. For vehicles being used for extended touring or heavy-duty towing, consider pairing this airbag system with upgraded shock absorbers for optimal load control and ride quality.

Yes, this Airbag Man Air Suspension Helper Kit (RR4581) is specifically designed to fit all Nissan Patrol MQ and MK series models (G/K/W160 chassis codes) manufactured between 1980 and 1988. The kit is compatible with all body styles including wagons, utes and troop carriers, as long as your vehicle has factory leaf spring rear suspension. If you've modified your suspension or are unsure about your specific variant, our team can confirm fitment – simply contact us with your vehicle's VIN or chassis number for verification.
This Airbag Man kit significantly enhances your Patrol's load-carrying capability by providing adjustable support from 5 to 100 PSI. While the exact weight capacity depends on your vehicle's existing suspension and GVM rating, airbag helper kits typically support an additional 500-800kg when properly inflated. The key benefit is load levelling rather than increasing your legal payload limit – always ensure your total vehicle weight remains within manufacturer specifications and legal GVM requirements. The airbags prevent sagging and maintain optimal suspension geometry under load, improving safety and handling rather than allowing you to exceed weight ratings.
This Airbag Man kit includes everything needed for installation: two heavy-duty reinforced rubber airbags designed for leaf spring mounting, all mounting brackets and hardware, high-quality nylon air line tubing, air line fittings and connectors, inflation valves for easy pressure adjustment, and comprehensive installation instructions with QR code access to online manuals. You won't need to source any additional components – the kit is genuinely complete. Basic hand tools and a vehicle jack are required for installation, but all suspension-specific hardware is provided in the box.
Absolutely – this is one of the primary applications for Airbag Man suspension helper kits. The adjustable air pressure allows you to compensate for tow ball weight, preventing rear sag and maintaining level ride height when towing caravans, camper trailers, boat trailers or any other towable loads. Level suspension is critical for safe towing as it maintains proper headlight aim, preserves steering geometry, ensures even brake force distribution, and reduces stress on your drivetrain. Simply adjust air pressure to achieve a level stance front-to-rear, which typically requires 50-100 PSI depending on your tow ball weight and trailer configuration.
No, control arm upgrades are not required when installing this airbag helper kit, as it works in conjunction with your existing leaf spring suspension rather than altering suspension geometry like a lift kit would. The airbags mount between the axle and chassis, providing supplementary load support without changing ride height or suspension travel characteristics. However, if your Patrol MQ/MK has worn bushings or you're planning a comprehensive suspension rebuild, upgrading other components alongside airbag installation can maximize overall performance. The airbag system is completely compatible with factory or aftermarket suspension components.
Wheel alignment is typically not required after installing airbag helper kits, as they don't alter your vehicle's suspension geometry, camber or caster angles like lift kits or replacement springs would. The airbags simply provide supplementary support to your existing leaf springs without changing mounting points or ride height (when deflated). That said, if your Nissan Patrol hasn't had an alignment check in several years or shows signs of uneven tyre wear, it's worth having alignment checked as part of good maintenance practice. Always verify all mounting hardware is torqued to specification after installation and recheck after 100km of driving.
Yes, this Airbag Man kit features independent left and right airbags with separate inflation valves, allowing you to adjust each side individually for perfectly level load compensation. This is particularly useful when carrying uneven loads such as toolboxes or equipment mounted to one side, or when towing with offset weight distribution. Independent adjustment also helps compensate for road camber during highway cruising or uneven terrain when off-roading. Each airbag can be inflated to different pressures ranging from 5 to 100 PSI, giving you complete control over load levelling and suspension balance across the rear axle.
This airbag helper kit does not provide suspension lift or increase tyre clearance – it's designed for load support and levelling rather than lifting your vehicle. When deflated (unladen condition), airbags have minimal impact on ride height, and when inflated under load, they prevent sag rather than raising the vehicle. If you want to fit larger tyres to your Nissan Patrol MQ/MK, you'll need a proper suspension lift kit with raised springs and extended shocks. Airbag kits are often installed alongside lift kits to provide the best of both worlds: increased ground clearance for larger tyres plus adjustable load support for towing and hauling.
Airbag Man products are backed by comprehensive manufacturer warranty coverage, reflecting the company's 25+ years of engineering excellence and product quality. Specific warranty terms vary by component, but typically include protection against manufacturing defects in materials and workmanship. Warranty coverage requires proper installation according to provided instructions, use within specified pressure limits (5-100 PSI), and normal operating conditions. The airbags themselves are built with heavy-duty multi-ply reinforced rubber designed for years of reliable service in harsh Australian conditions. For detailed warranty terms and registration information, refer to the documentation included with your kit or contact 4WD Suspension Australia directly.
This Airbag Man kit is perfectly suited for both daily driving and loaded touring – that's the key advantage of adjustable air suspension. For everyday unladen driving, simply deflate the airbags to 5-10 PSI or completely deflate them, allowing your factory leaf springs to provide normal ride characteristics without interference. When you load up for a weekend trip or hook up a trailer, inflate the airbags to the pressure needed to restore level ride height. This versatility means you don't sacrifice daily comfort for occasional towing capability. The airbags are extremely durable and designed for constant inflation/deflation cycles, making them ideal for vehicles that switch between empty commuting and heavy-duty touring or work use.
Perfect for Family Camping Trips Up North
Fitted these airbag helper springs to our old MQ Patrol before heading up to Cape York with the family and caravan. The difference in handling and ride quality was night and day - no more sagging rear end when loaded up with camping gear and water. Installation was straightforward enough for a weekend job in the shed, and the adjustability means I can fine-tune it depending on whether we're towing or just loaded with swags and eskies.(5)
Perfect for My Old MK Patrol
Been running these airbag helpers on my MK for about six months now and they've completely sorted out the sag when I'm loaded up with tools and materials. The difference in ride quality is night and day, especially when I'm carrying a full load of timber or machinery. Installation was straightforward enough to do in the driveway over a weekend, and they've handled everything from daily site work to a few beach trips without any dramas.(5)
Perfect for Our Loaded Family Camping Trips
Added these air suspension helpers to our MQ Patrol before our last trip up to the High Country and the difference was night and day. The rear end no longer sags when we've got the camper trailer, kids' gear, and all the camping equipment loaded up. Ride quality improved heaps too, especially on corrugated roads where the back used to bounce around. Well worth the investment for anyone doing regular touring with a loaded rig.(5)
