This kit comes in two variants to suit your current suspension configuration. The CR5123HP is designed for MU-X vehicles with factory standard suspension height, while the CR5122HP is specifically engineered for vehicles already fitted with 40-50mm suspension lifts. Choosing the correct variant ensures proper airbag geometry, optimal working range, and prevents potential contact with suspension or chassis components. If you've installed a lift kit after purchase, or plan to do so, select the CR5122HP variant. The high pressure technology in both variants delivers exceptional load support regardless of your suspension height.
The Airbag Man Helper Kit is designed for straightforward installation by experienced DIY enthusiasts or professional workshops, with an estimated fitment time of approximately 120 minutes. The kit includes comprehensive step-by-step instructions accessible via QR code, along with all necessary mounting brackets, hardware and air lines. No cutting or welding is required - installation uses existing chassis mounting points. While the airbag system works independently with your existing suspension, if you're running heavy loads regularly, consider upgrading to heavy-duty shock absorbers for optimal ride quality. Professional installation is recommended if you're unfamiliar with suspension work, and a post-installation check of all components is essential before loading the vehicle.

This Airbag Man kit is specifically engineered for Isuzu MU-X UCS40 series from 2021 onwards, covering both 4x2 and 4x4 variants. The kit comes in two options: CR5123HP for factory standard height suspension, and CR5122HP for vehicles with 40-50mm lift kits already installed. To confirm exact fitment for your specific build date and variant, check your vehicle details against our parts finder or contact our team with your VIN number. All current generation MU-X models from 2021-2023+ are compatible with this system.
The high pressure airbag system doubles the pressure capacity of standard airbags, operating up to 100 PSI compared to 50 PSI for conventional systems. This translates to significantly increased load support and levelling capability - typically handling an additional 500-800kg of rear-end payload or tow ball weight depending on your vehicle's factory GVM. The adjustable nature means you can fine-tune pressure to match your exact load, from empty daily driving at low pressure to maximum support when fully loaded or towing heavy caravans. The system works in conjunction with your existing coil springs, not as a replacement, providing supplementary support where it's needed most.
This is a comprehensive kit including everything needed for installation: two Firestone high pressure polyurethane airbags with protective sleeves, vehicle-specific mounting brackets and hardware for both front and rear coil springs, high pressure inflation valves with dust caps, nylon air line tubing with quick-connect fittings, and a complete bolt kit. You also get detailed step-by-step installation instructions accessible via QR code on the packaging. The kit is available in two variants - choose CR5123HP for standard height or CR5122HP for 40-50mm lifted suspensions. The only item not included is an air compressor, which can be a simple manual pump, portable 12V compressor, or permanently mounted in-vehicle system.
Absolutely - this high pressure system is ideal for regular towing applications and is one of the most popular upgrades among Australian caravan towers. The adjustable airbags eliminate rear-end squat that occurs when heavy tow ball weight compresses your rear suspension, restoring proper vehicle geometry for safer steering and braking. You can adjust air pressure to perfectly match your specific caravan or trailer weight, maintaining level ride height and even weight distribution. The system dramatically improves towing stability by reducing body roll and sway, while ensuring your headlights maintain correct aim. Many MU-X owners towing 2500-3000kg caravans report this upgrade as transformative for towing confidence and safety.
The Airbag Man helper kit works perfectly with your factory coil springs, shock absorbers and control arms - no other components need replacement for the airbag system to function. However, if you're regularly carrying heavy loads or have noticed worn suspension bushes, upgrading to heavy-duty shock absorbers and polyurethane bushes will further improve ride quality and handling under load. If you've installed or are planning a suspension lift beyond 50mm, upgraded control arms may be required to maintain correct suspension geometry, but this is related to the lift itself rather than the airbag system. The beauty of this kit is its versatility - it enhances your existing suspension setup without requiring a complete overhaul.
No wheel alignment is required after installing this airbag helper kit, as it doesn't alter your suspension geometry or ride height when set at appropriate pressure. The airbags work within your existing coil spring assembly and don't affect camber, caster or toe settings. However, it's always good practice to have your alignment checked if you notice uneven tyre wear or if your vehicle pulls to one side. If you're installing this kit at the same time as a lift kit or replacing other suspension components like control arms or springs, then a full four-wheel alignment would be necessary. The airbags themselves simply require periodic pressure checks to ensure they're inflated to suit your current load.
One of the best features of this system is how easy it is to adjust - you can inflate or deflate the airbags yourself in minutes using any standard air source. The kit includes inflation valves mounted in an accessible location (typically near the rear bumper or inside the rear cargo area), and you can use a simple bicycle pump, portable 12V air compressor, or service station air line to adjust pressure. Many MU-X owners install an in-vehicle air management system with cab-mounted gauges and controls for ultimate convenience. You can adjust pressure on-the-fly to match your load - run at low pressure (20-30 PSI) for empty daily driving comfort, then increase to 60-100 PSI when loaded or towing. A simple tyre pressure gauge lets you monitor and adjust as needed.
This airbag helper kit is designed to support load carrying and maintain proper ride height rather than provide suspension lift for tyre clearance. When inflated, the airbags restore your MU-X to factory ride height even under heavy loads, but they don't raise the vehicle higher than standard unladen height. If your goal is fitting larger tyres, you'll need a proper suspension lift kit first, and then you'd choose the CR5122HP variant of this airbag kit designed for 40-50mm lifted vehicles. The airbags are excellent for maintaining clearance you already have - preventing the vehicle from sitting lower when loaded, which would reduce tyre-to-guard clearance. Many MU-X owners combine a 40-50mm lift with the CR5122HP airbag kit to fit larger tyres while maintaining load-carrying capability.
This kit features Firestone airbags backed by an industry-leading lifetime manufacturer's warranty, providing exceptional peace of mind and demonstrating the quality and durability of the components. This warranty covers manufacturing defects and premature failure of the airbags themselves under normal use conditions. The mounting hardware, brackets, air lines and fittings are covered by Airbag Man's standard warranty terms. To maintain warranty coverage, ensure the kit is installed according to the provided instructions, airbags are operated within the specified pressure range (check the airbag sidewall markings), and the system is used for its intended purpose of load support. With over 25 years of Australian operation, Airbag Man stands behind their products with excellent customer service and warranty support.
This system is excellent for daily driving as well as heavy load situations - that's the beauty of adjustable air suspension. When your MU-X is empty or lightly loaded for daily commuting, school runs or shopping trips, you can run the airbags at low pressure (20-30 PSI) or even completely deflated, and your factory coil springs and shocks provide normal ride comfort. When you load up for weekend adventures, carry work equipment, or hook up a caravan, simply increase air pressure to support the additional weight. This adjustability means you get comfortable daily driving without the harsh ride of permanently fitted heavy-duty springs, while still having serious load support capability when needed. It's the perfect solution for vehicles that serve dual purposes - family transport during the week and adventure vehicle on weekends.
Perfect for Heavy Touring Loads
Been running these Airbag Man helper kits on my MU-X for six months now, including a Simpson Desert crossing and multiple Cape York trips. The difference when loaded with camping gear, water, and recovery equipment is night and day - no more sagging rear end and the ride quality actually improves compared to maxing out the standard coils. Fitment was spot-on and they've handled corrugations and bulldust without any issues whatsoever.(5)
Perfect Solution for Our Loaded MU-X
These Airbag Man helper springs have been a game-changer for our family camping trips in the MU-X. Previously the rear would sag noticeably with the camper trailer, two bikes, and all our gear loaded up, but now it sits level and handles much better on corrugated roads. Installation was straightforward and the adjustable pressure means we can fine-tune it depending on the load. Well worth the investment for anyone who regularly tours with a heavy setup.(5)
Perfect for Daily Work Loads and Weekend Trips
Been running these airbag helpers on my MU-X for three months now and they've completely sorted the rear sag when I'm loaded up with tools and materials. The adjustability means I can run them soft for the daily commute and pump them up when I'm towing the work trailer or heading bush on weekends. Installation was straightforward enough and the build quality feels proper, not some cheap knockoff that'll give up after a year.(5)
Perfect Solution for Our Loaded Family Camper
Fitted these airbag helpers to our MU-X before our last trip down the coast and the difference with a full load of camping gear and kids in the back was night and day. No more sagging rear end or that awful wallowy feeling on the highway. Installation was straightforward enough for a weekend DIYer, and being able to adjust the pressure depending on the load is brilliant for how we use the vehicle.(5)
