The beauty of air suspension is infinite adjustability — unlike fixed-rate coil or leaf springs, you simply adjust air pressure to match your current load. For daily driving with minimal cargo, run 20-30 PSI for comfortable ride quality. When loading up for a camping trip with rooftop tent, dual battery system, fridge, water tanks, and recovery gear in the tub, increase to 50-70 PSI. Towing a 2500-3000kg caravan or boat trailer requires 80-100 PSI for optimal load levelling and stability. The kit allows you to fine-tune pressure in 5 PSI increments to find the perfect balance between load support and ride comfort for any situation.
This is an Easy Fit Kit designed for straightforward bolt-on installation with an estimated 120-minute fitment time for experienced DIY mechanics with basic hand tools. The kit includes vehicle-specific mounting brackets that attach to existing chassis points without drilling or permanent modification. Professional installation is recommended if you're unfamiliar with suspension work. After installation, adjust air pressure according to your load — start at 30 PSI and increase in 10 PSI increments until the vehicle sits level. Allow a 500km break-in period for airbags to fully seat before running maximum pressure. When upgrading to lifted suspension, consider pairing with upgraded shock absorbers for balanced performance.

This helper kit is ideal for D-Max owners who regularly carry heavy loads or tow caravans, camper trailers, and boat trailers. Tradespeople using their ute for work will appreciate the ability to maintain proper ride height when carrying tools, materials, and equipment in the tub. Touring enthusiasts with slide-on campers, roof-top tents, dual battery setups, and long-range fuel tanks will benefit from adjustable load support that prevents rear-end sag and maintains safe handling.

This kit is specifically engineered for Isuzu D-Max models manufactured from June 2012 through July 2020 (first-generation RG series). It fits all variants including LS-M, LS-U, SX, and X-Terrain with factory leaf spring rear suspension. Two fitment options are available: RR4707 for standard height vehicles and RR4717 for D-Max utes with 2-inch lifted suspension. If you're unsure about your specific vehicle or have aftermarket modifications, contact our team for confirmation before ordering.
This helper kit doesn't technically increase your vehicle's legal GVM (Gross Vehicle Mass) rating, but it provides the suspension support to safely carry loads up to your manufacturer's rated capacity without sagging or bottoming out. The Firestone airbags can support significant weight when inflated to maximum 100 PSI, effectively restoring proper ride height and handling when carrying heavy cargo, towing caravans, or hauling boat trailers. The adjustable nature means you can fine-tune support for any load from empty to maximum GVM.
The kit includes everything required for installation: two premium Firestone commercial-duty airbags, vehicle-specific mounting brackets and hardware, high-pressure rated nylon air line tubing, inflation valves and fittings, complete fastener kit, and detailed step-by-step instructions with QR code access to online guides. You won't need to source any additional parts — it's a complete bolt-on solution designed for straightforward fitment. The kit is available in two variants to suit standard height (RR4707) or 2-inch lifted suspensions (RR4717).
Absolutely — this is one of the most popular applications for air helper kits on the Isuzu D-Max. When towing caravans or heavy trailers, the rear suspension naturally compresses due to towball weight, reducing ground clearance and compromising steering and braking performance. This airbag system allows you to inflate the bags to 80-100 PSI when towing, maintaining proper ride height and weight distribution for safer, more stable towing. You'll experience reduced body roll, improved steering response, and better braking control when loaded.
No, control arms are not required for this installation as it's a helper kit that works with your existing leaf spring suspension — not a replacement suspension system. The airbags mount between the leaf springs and chassis, providing supplementary support without altering suspension geometry. However, if you're installing the RR4717 version for lifted suspensions or planning other suspension modifications, upgraded control arms may be beneficial for maintaining proper alignment angles. Our team can advise on complementary upgrades for your specific setup.
A wheel alignment check is recommended after any suspension modification, though this helper kit doesn't typically affect alignment angles significantly since it works within the existing leaf spring system rather than altering suspension geometry. If you're installing the RR4717 variant alongside a 2-inch lift kit, professional alignment is mandatory to ensure correct camber, caster, and toe settings. Proper alignment ensures even tyre wear, optimal handling, and safe vehicle operation, especially when carrying heavy loads or towing.
Yes — adjustability is the key advantage of air suspension systems. External inflation valves allow you to adjust air pressure in minutes using a standard air compressor or service station air line. Run 20-30 PSI for comfortable daily driving with minimal load, increase to 50-70 PSI when carrying camping gear and equipment, and inflate to 80-100 PSI when towing heavy caravans or trailers. This infinite adjustability means one kit suits all load conditions, unlike fixed-rate helper springs that offer no tuning capability.
This airbag helper kit doesn't provide body lift or increase clearance for larger tyres — it's designed to maintain proper ride height when loaded rather than raise the vehicle. If you're running the standard RR4707 version, tyre clearance remains unchanged from factory specifications. The RR4717 variant is designed for vehicles already fitted with 2-inch lift kits, which typically allow 31-32 inch tyres depending on wheel offset. For significant tyre size increases, you'll need a proper suspension lift kit with raised springs and extended shocks.
The Firestone airbags included in this kit are covered by a lifetime manufacturer's warranty against defects in materials and workmanship, providing exceptional long-term value and peace of mind. This warranty covers the airbag units themselves and reflects Firestone's confidence in their commercial-grade construction and durability. Mounting hardware, fittings, and air lines carry standard manufacturer warranty coverage. Airbag Man's 25+ year reputation for quality and customer service means you're supported long after purchase with local Australian technical assistance.
Yes — when properly adjusted, air suspension actually improves ride comfort compared to factory leaf springs alone, especially when unladen. Running lower air pressure (20-35 PSI) for daily driving provides a more compliant, cushioned ride that absorbs bumps and road imperfections better than steel springs. The progressive spring rate of airbags means they start soft for comfort but become progressively firmer under load for control. This makes the D-Max more pleasant for daily commuting while still providing heavy-duty load support when needed — the best of both worlds.
Perfect for Towing the Camper Trailer
Fitted these airbag helpers to my 2015 D-Max before our trip up to Fraser Island and what a difference they made. The back end used to sag noticeably with the camper trailer loaded up, but now it sits level and handles so much better on the highway. Installation was straightforward enough to do in the driveway over a Saturday morning, and the ride quality is genuinely improved even when not towing.(5)

Fitted these airbag helpers to our 2015 D-Max before our last trip to the High Country and the difference with a full load of camping gear and the family is night and day. The rear end sits level now instead of sagging, and the ride quality on corrugated tracks is so much better. Installation was straightforward enough for a weekend in the shed, and they've handled everything from beach sand to rocky fire trails without any issues.(5)
Best upgrade for my loaded work truck
Been running these airbag helpers on my D-Max for about 6 months now and they've completely sorted the sagging issue when I'm loaded up with tools and materials. The difference in handling when towing the trailer is night and day - actually sits level now instead of squatting like it used to. Installation was pretty straightforward for anyone handy with the spanners, and the quality seems solid for daily tradie use.(5)
