The Airbag Man Air Suspension Helper Kit suits the Nissan Patrol MQ/MK leaf spring rear end, working alongside your factory leaf springs rather than replacing them. Air pressure is adjustable across the full load range, so you can dial in support for towing, canopy weight or camper loads without swapping out your leaf springs. Two heavy-duty air bags with brackets, valves and fittings are supplied for a bolt-in fit. Dispatched from Australian stock now, backed by manufacturer warranty and fitment support from our team.

This kit is a helper system rather than a spring replacement, so it works with whatever leaf spring rate is already fitted to your Patrol. If you're running a heavier constant load such as a tray, canopy, dual battery tray, long-range fuel tank or slide-on camper, air pressure alone may not be enough and you should also consider a higher-rated leaf spring to carry that weight day-to-day. Keep the air bags for the variable load — trailer tow ball weight, water in the tank, or gear you only carry sometimes.
Fitment uses the factory mounting points on the axle housing and chassis rail, and most experienced DIY installers can complete the job with common hand tools in a home workshop. Wheel alignment is not typically required after fitting an air bag helper kit alone, since it doesn't change static ride height or suspension geometry. If you've also fitted new leaf springs or shocks at the same time, a wheel alignment check is worthwhile. These vehicles use solid axles on leaf springs, with no control arms or struts to upgrade; caster at lift height is corrected with caster wedges between the axle and leaf pack, and extended shackles or brake lines may be needed depending on the kit.
Airbag Man has been manufacturing air suspension products in Australia for over 25 years, with air bag kits designed and tested locally for Australian towing and touring conditions. Every kit is backed by a manufacturer warranty and supplied with full fitting instructions so you know exactly what you're installing. Tradespeople and tourers running the Patrol MQ/MK leaf spring rear choose Airbag Man because the kit works with the standard springs rather than needing a full suspension change — view the full Airbag Man range for other Patrol options.
This kit suits Patrol MQ/MK owners who tow a trailer, caravan or boat regularly and need to correct rear sag without permanently stiffening their ride. It's also a practical option for tradies carrying tools, water or generators in the tray, and tourers running camper trailers where the load changes from trip to trip. If your load is more constant than variable, browse our airbag suspension range alongside heavier-rated leaf springs for a combined solution.
This kit is dispatched from Australian stock with fitment guidance from our in-house team on hand if you have questions about your specific Patrol. Browse our full lift kit range or check compatible parts using our Nissan Patrol parts finder before you order.

Yes, this Airbag Man helper kit is designed specifically for the leaf spring rear end fitted to the Patrol MQ and MK. It mounts to the factory axle housing and chassis rail mounting points, so no drilling or cutting is required on a standard rear end. If your Patrol has had aftermarket leaf springs or a lift kit fitted, check with our team first to confirm bracket clearance. Contact our fitment support if you're unsure which rear end your Patrol has.
This is a load-support helper kit, not a lift kit, so it doesn't raise your Patrol's static ride height. Instead, the air bags inflate to counteract sag once you add weight — towing, a canopy or camper — bringing the rear back to level under load. Unladen, the air bags sit largely inactive and your leaf springs carry the vehicle as normal. If you want a permanent ride height increase, look at our leaf spring range instead.
This vehicle runs solid axles on leaf springs, so there are no upper or lower control arms or struts like an IFS vehicle. When lifting with taller leaf springs, caster change is corrected with caster wedges fitted between the front axle and the leaf packs, and longer shackles or extended brake lines may be needed depending on lift height. Our team can advise what your build needs.
Yes, correcting rear sag under tow ball weight is the main reason Patrol owners fit this kit. By adjusting air pressure to suit the load, you can keep the rear end level when towing a caravan, boat or trailer, which improves headlight aim and handling. It's a variable-load solution, so you air up for towing and can air down again for unladen driving. For constant heavy loads, pairing it with a higher-rated leaf spring gives more consistent support.

Wheel alignment is not typically required after fitting this air bag helper kit alone, because it doesn't change your Patrol's ride height or suspension geometry. If you're fitting new leaf springs, shocks or a front-end lift at the same time, get an alignment check done once everything is installed. Our team can advise on alignment needs based on your full suspension setup.
This air bag kit works with whatever leaf spring rate is already fitted to your Patrol, so it doesn't replace your springs. If you're carrying a constant heavy load such as a tray, canopy or long-range fuel tank, a higher-rated leaf spring alongside this kit will give more consistent day-to-day support. Use the air bags for variable loads like trailer tow ball weight or occasional gear.
Because this kit doesn't raise ride height, it won't create extra tyre clearance on its own. Tyre fitment depends on your existing setup and any separate lift components you've fitted. If you're planning larger tyres, check clearance requirements with our team alongside any front-end lift you're considering.
This kit is covered by Airbag Man's manufacturer warranty, reflecting over 25 years of local air suspension manufacturing experience. Specific warranty terms are confirmed at the time of purchase and cover manufacturing defects in the air bags and hardware. Our team can provide full warranty documentation before or after you order.
Yes, the air bags can be left at low or minimal pressure for unladen daily driving, letting your factory leaf springs handle normal ride comfort. You simply air up when you load the vehicle for towing, work or touring, then air back down afterwards. This makes it practical for Patrols used for both daily commuting and occasional heavy-load trips.
