Kit Options: CR5122HP suits standard height suspension / CR5133HP suits 2-inch (50mm) lifted suspension. Both options fit 4x2 and 4x4 variants with factory coil spring rear suspension.
Choose between the CR5122HP for factory standard ride height or the CR5133HP if you've already installed a 2-inch (50mm) suspension lift. Both kits deliver identical performance benefits with the only difference being the airbag mounting bracket design to accommodate the changed suspension geometry. Consider your typical load requirements: the high-pressure design excels when regularly towing caravans over 2000kg, carrying slide-on campers, or hauling heavy work equipment in the cargo area. For lighter recreational use with occasional load carrying, this kit still provides excellent insurance against spring sag and ride deterioration.
The Airbag Man High Pressure Helper Kit is designed as an Easy Fit system with an estimated installation time of 120 minutes for experienced DIY mechanics with proper tools and equipment. The kit includes comprehensive step-by-step instructions accessible via QR code and the Airbag Man website, complete with diagrams and torque specifications. While mechanically inclined owners can install this system, professional fitting is recommended to ensure correct placement, secure mounting, and proper air line routing away from heat sources and moving components. No modifications to the factory suspension are required, and the system can be removed if needed without permanent changes to the vehicle. After installation, test the system at various pressures and inspect all fittings and connections for leaks before putting the vehicle under load.

This Airbag Man helper kit is available in two configurations to match your Isuzu MU-X suspension setup:
Both options deliver identical performance characteristics with the high-pressure sleeve technology—the only difference is the mounting bracket geometry to ensure proper airbag fitment and optimal suspension travel within the available space. Always select the option matching your current suspension height to ensure correct installation and performance.
The Airbag Man High Pressure Helper Kit requires minimal ongoing maintenance to deliver years of reliable service. Inspect airbags visually every 3-6 months for signs of abrasion, cuts, or excessive wear, particularly where they contact mounting hardware or suspension components. Check air pressure monthly and adjust as needed based on your current load—the system may naturally lose a few PSI over time, which is normal. Every 12 months, inspect all airline connections, fittings, and inflation valves for leaks using soapy water, and ensure mounting brackets remain tight to manufacturer torque specifications. When washing your MU-X, avoid directing high-pressure water directly at the airbags or inflation valves. This simple maintenance routine ensures maximum lifespan and consistent performance from your investment.
This kit fits all Isuzu MU-X models from 2013 to current, covering both the first generation (UCS85, 2013-2021) and second generation (2021-current) across 4x2 and 4x4 variants. You must select the correct option: CR5122HP for standard height suspension or CR5133HP if you have a 2-inch lift kit installed. Both options work with factory coil spring rear suspension. If you've fitted other aftermarket suspension components or have a non-standard setup, contact us to confirm compatibility before ordering.
The Airbag Man High Pressure Helper Kit can support up to 500kg of additional load on the rear axle when inflated to the maximum 70 PSI rating. This doesn't increase your vehicle's legal GVM rating but helps maintain proper ride height and suspension geometry when operating at or near your MU-X's factory-rated capacity. The high-pressure design is particularly effective for towing caravans and trailers, where significant towball download (typically 200-350kg) can cause rear spring sag. The system allows you to dial in the exact support needed based on your actual load, from 5 PSI for empty running to full pressure for maximum weight.
The kit includes everything needed for installation: two Firestone high-pressure airbags with protective sleeves, vehicle-specific mounting brackets, Schrader inflation valves with caps, nylon air line tubing, all fittings and hardware, plus comprehensive instructions with QR code access. The only item not included is an air compressor for inflation—you can use a service station air hose, portable compressor, or add an on-board compressor system for ultimate convenience. All components are backed by Airbag Man's lifetime warranty on the Firestone airbags and 12-month warranty on hardware.
Yes, this high-pressure kit is specifically engineered for regular towing applications and is one of the most popular upgrades among MU-X owners who tow caravans. The system eliminates the rear-end sag that occurs from towball download, maintains proper headlight aim, improves steering feel and braking performance, and reduces sway when towing in crosswinds. The ability to adjust pressure based on actual towball weight means you get optimal support whether towing a small box trailer or a 2800kg caravan at the MU-X's maximum rated capacity. Many owners report significantly improved confidence and comfort when towing after installing this system.
The Airbag Man Helper Kit works perfectly with your factory suspension components and doesn't require any mandatory upgrades to shocks, springs, or control arms. However, if you're regularly operating at high loads or have noticed your existing shock absorbers are worn, this is an ideal time to consider upgraded shocks that better complement the airbag system's capabilities. Similarly, if you're running a 2-inch lift (CR5133HP option), quality aftermarket shocks and potentially upgraded control arms will maximize the complete system's performance. The airbags themselves are compatible with any shock absorber brand and work alongside your existing coil springs.
Wheel alignment is not typically required after installing airbag helper springs because the kit mounts within the existing suspension geometry without altering suspension mounting points or ride height when set at low pressure. However, it's good practice to have your alignment checked if your MU-X hasn't had one recently, particularly if you're also installing a lift kit alongside these airbags. If you notice uneven tyre wear or steering pull after installation, have your alignment inspected. The adjustable nature of the system means you can fine-tune ride height without affecting alignment once properly set up.
Air pressure adjustment is simple and requires no special equipment—just a standard air hose and pressure gauge like you'd use for checking tyres. The kit includes Schrader valves (same as tyre valves) mounted in accessible locations, allowing you to inflate or deflate using any air compressor at service stations, portable compressors, or an on-board system. Start with 20-30 PSI for moderate loads and adjust up or down based on how the vehicle sits and handles. Many owners carry a portable compressor and gauge to make fine adjustments on the road, particularly useful when load conditions change during touring trips.
The Airbag Man Helper Kit maintains or slightly increases rear ride height when inflated but is not designed as a primary lift kit for tyre clearance. If you have the standard CR5122HP option, you won't gain significant clearance for larger tyres. The CR5133HP option is designed for vehicles already running a 2-inch suspension lift, which typically allows 265/65R17 or 265/70R17 tyres depending on wheel offset and other modifications. The airbags' primary purpose is load support and ride height maintenance under load rather than providing lift for tyre clearance. For significant tyre size increases, consider a dedicated lift kit alongside the airbag system.
The Firestone airbags included in this kit are backed by a lifetime manufacturer's warranty against defects in materials and workmanship, demonstrating the exceptional quality and durability of these components. All other kit components including mounting hardware, brackets, fittings, and air lines carry a 12-month warranty from date of purchase. The warranty covers manufacturing defects but doesn't cover damage from incorrect installation, vehicle accidents, or excessive wear from operating beyond rated capacity. Airbag Man's 25-year reputation in Australia means warranty claims are handled fairly and efficiently, giving you complete peace of mind in your investment.
This kit excels in both daily driving and heavy-duty applications thanks to its adjustable pressure range from 5 PSI to 70 PSI. For daily driving with no load, simply deflate to minimum pressure (5-10 PSI) and you'll enjoy the factory ride quality with the added benefit of supporting the rear springs and reducing wear. When you load up for a weekend trip or hook up the caravan, inflate to the appropriate pressure and enjoy level, controlled handling. This versatility makes the high-pressure kit ideal for vehicles that serve dual purposes—family transport during the week and serious towing or load carrying on weekends and holidays. The system adapts to your needs rather than forcing compromise.
