The Airbag Man Air Suspension Helper Kit (RR4707) fits Isuzu D-MAX 2008-2012 models with factory leaf springs and adds adjustable air support from 5 to 100 PSI on demand. It works alongside your existing rear leaf pack rather than replacing it, so unladen ride height stays factory-correct while towing or hauling gear firms up the rear. The kit includes twin airbags, mounting hardware, air line and fittings, backed by Airbag Man's manufacturer warranty. In stock in Australia now with fitment support from our team.

This kit doesn't replace your leaf spring rate — it adds adjustable air pressure on top of your factory leaf springs, so you set the PSI to match the load rather than choosing a fixed spring rate. Start low (around 15-20 PSI) for daily unladen driving and increase toward the 100 PSI ceiling as you add a caravan tow ball weight, canopy, tray load, water tanks or a bullbar-mounted winch. If your accessory load is constant and heavy, pair this helper kit with a higher-rated leaf spring upgrade so the leaf pack itself carries more of the base load.
Fitting is a bolt-on job that an experienced DIY installer with basic tools can complete, though we recommend a suspension workshop if you're not confident working around the rear axle. Because this kit adds adjustable air support to the existing leaf springs rather than changing unladen ride height, a wheel alignment isn't mandatory after fitting on its own — but have your alignment checked if you're also installing new leaf springs or shocks at the same time. Air up gradually and check hose fittings for leaks after the first few hundred kilometres of use. Consider pairing this kit with upgraded control arms if you're also lifting the front end for a fully levelled stance.
Airbag Man has built a 25-year reputation manufacturing air suspension products for Australian conditions, from tradie utes to caravan tow rigs.

This kit suits D-MAX owners who tow caravans or trailers, tradespeople carrying tools and materials in the tray, and grey nomads loading up water and gear for touring. If you're regularly switching between an empty ute and a fully loaded one, this airbag suspension setup lets you dial in support only when you need it.

This helper kit (RR4707) is designed for Isuzu D-MAX models built 2008-2012 with the factory rear leaf spring setup. The mounting brackets are vehicle-specific to this chassis, so it's a direct bolt-on for that model range. If your D-MAX has already had leaf springs replaced or the rear end modified, check with our team before ordering. Contact our suspension experts if you're unsure of your build date or spec.
This is a load-support helper kit, not a lift kit — it doesn't raise your D-MAX's unladen ride height. Instead it adds adjustable air pressure from 5 to 100 PSI that firms up the rear only when you're carrying weight, reducing sag under load. If you're after a permanent height increase, look at our dedicated leaf spring upgrades instead. This kit is best paired alongside your existing suspension setup.
The kit includes two Airbag Man rear airbags, vehicle-specific mounting brackets, air line, an inflation valve, fitting hardware and easy-fit instructions. It's designed to work with your factory leaf springs — no leaf spring replacement is needed. A dedicated in-cab compressor or gauge system is sold separately unless specified on your order. Check the kit contents list on this page for the exact inclusions.
Yes, this is exactly what the kit is built for. Airing up to match your caravan or trailer tow ball weight reduces rear sag, improves brake balance and keeps headlights aimed correctly instead of pointing skyward. Many D-MAX owners run low pressure unladen and increase PSI only when hitched up. It's a practical, adjustable solution for variable towing loads.
No, this rear air helper kit doesn't require a control arm upgrade since it works with the factory rear leaf springs, not the front suspension. Control arm upgrades are more relevant if you're also fitting a front lift kit or coil springs. If you're planning a fuller suspension upgrade later, our control arms range covers that separately.
Not specifically for this kit on its own, because it doesn't change your D-MAX's unladen ride height or geometry. If you're fitting new leaf springs, shocks or a front lift kit at the same time, have the alignment checked as part of that job. Otherwise the airbags simply add support that you dial up when loaded.
This kit adjusts air pressure rather than spring rate, so you set the PSI (5-100) to suit your current load instead of choosing a fixed spring. If your D-MAX carries a constant heavy load — a permanent canopy, tool boxes or water tanks — pairing this kit with a higher-rated leaf spring gives you a stiffer base rate plus the adjustable airbag support on top.
Because this kit doesn't change unladen ride height, it won't create extra clearance for larger tyres on its own. If you want more clearance for bigger rubber, you'll need a genuine lift kit with raised leaf springs or coils. Speak with our team about combining a lift kit with this helper kit if you want both extra height and load support.
This Airbag Man helper kit is backed by the manufacturer's warranty, covering the airbags and included hardware against defects. Airbag Man has been manufacturing air suspension products in Australia for over 25 years. Keep your proof of purchase and contact our team if you have any warranty questions after fitting.
Yes. Run low PSI (around 15-20 PSI) for everyday unladen driving so the ride stays soft, then increase pressure only when you're loaded up for a trip or towing job. Because the airbags work alongside your factory leaf springs rather than replacing them, daily comfort isn't compromised. It's designed to be adjusted as your load changes from one trip to the next.
