The AIRBAG MAN CR5050 kit provides variable load support based on air pressure — inflate to match your current rear axle load for optimal performance. Start with 20-30 PSI for moderate loads (camping gear, roof racks, bullbar), increase to 50-70 PSI for heavier setups (dual battery systems, long-range fuel tanks, rear drawers), and up to 80-100 PSI when towing caravans or camper trailers approaching maximum GVM. Common rear accessories that affect load requirements include: rear drawers and fridge systems, roof-mounted tents and awnings, dual spare wheels, water tanks, toolboxes, and heavy-duty rear bars. Always check your vehicle's GVM rating and ensure total loaded weight remains within manufacturer specifications.
This kit requires drilling for mounting bracket installation and is best suited for experienced DIY installers or professional workshops — estimated fitment time is approximately 120 minutes. The airbags mount between the factory coil springs and chassis using the supplied brackets and hardware, with inflation lines routed to a convenient location for access. Post-installation, start with low air pressure (5-10 PSI) and gradually increase based on your load — the system is fully adjustable so you can fine-tune for different scenarios. While wheel alignment is not required for airbag helper installation (unlike lift kits), it's recommended to check alignment if your vehicle has been heavily loaded or towing for extended periods.

This AIRBAG MAN kit (CR5050) is specifically designed to fit Toyota Landcruiser 100 Series models from 1998-2007, including HDJ100, HDJ101R (4.2L diesel), and UZJ100 (4.7L V8 petrol) variants with factory coil spring rear suspension. The kit is engineered for the IFS (Independent Front Suspension) 100 Series with rear coil springs. If you have a 105 Series with leaf spring rear suspension, you'll need a different airbag kit designed for leaf spring applications. Check your vehicle's compliance plate or contact our team if you're unsure of your exact model variant.
The AIRBAG MAN CR5050 kit provides variable load support up to approximately 1200kg per axle when inflated to maximum pressure (100 PSI). However, it's critical to understand that airbag helper springs do NOT increase your vehicle's legal GVM (Gross Vehicle Mass) rating — they simply help your existing suspension carry loads more effectively within your factory GVM limits. The kit eliminates rear sag and improves stability when carrying heavy loads or towing, but you must still comply with your Landcruiser 100 Series's maximum rated payload capacity. Always check your vehicle's compliance plate and ensure your loaded weight (including passengers, fuel, accessories, and towed load) remains within legal limits.
This complete AIRBAG MAN kit includes everything needed for installation: 2 heavy-duty air springs (airbags) designed for coil spring suspension, all mounting brackets and hardware, nylon air line tubing, brass push-to-connect fittings, inflation valves, and detailed step-by-step instructions with QR code access. The kit is designed to be comprehensive so you won't need to source additional components. Note that an air compressor is not included — you can inflate the airbags using a portable compressor, service station air, or invest in an optional onboard compressor system for convenient adjustments on the go. All fasteners and installation hardware are supplied.
Yes, this AIRBAG MAN kit is excellent for towing applications and is one of the most popular upgrades for Landcruiser 100 Series owners who tow caravans or camper trailers. The adjustable air pressure allows you to dial in the exact support needed to maintain level ride height and prevent dangerous rear squat that affects steering control and braking performance. When towing heavy loads, inflate the airbags to 70-100 PSI to eliminate sag and improve stability. The kit keeps your headlights aimed correctly (preventing glare to oncoming traffic) and maintains proper suspension geometry for safer towing. Many customers also pair this kit with upgraded shock absorbers for even better towing performance and control.
No, control arm upgrades are not required when installing this airbag helper kit, as it works with your factory suspension geometry and doesn't alter suspension mounting points like a lift kit does. The airbags simply provide additional support between your existing coil springs and chassis. However, if your Landcruiser 100 Series already has worn or damaged control arm bushes, or if you're planning a suspension lift in the future, it's worth inspecting your control arms during installation. If you do decide to lift your vehicle later, upgraded control arms with adjustable camber correction become important for maintaining proper wheel alignment and preventing premature tyre wear.
Wheel alignment is not mandatory after installing this airbag helper kit, as it doesn't alter your Landcruiser's suspension geometry or ride height in the same way a lift kit does — the airbags work within your existing suspension travel. However, if your vehicle has been heavily loaded or used for extensive towing before installation, it's good practice to have your alignment checked to ensure even tyre wear and optimal handling. If you've been experiencing uneven tyre wear or pulling to one side, have your alignment inspected regardless of airbag installation. The airbags themselves won't affect alignment when properly installed and adjusted to appropriate pressure for your load.
Yes, adjustability is the key advantage of this AIRBAG MAN system — you can change air pressure in minutes to match your current load. When running empty or with light loads, reduce pressure to 5-20 PSI (or even fully deflate) to maintain your factory ride comfort. When loaded with camping gear, increase to 30-50 PSI for moderate support. When towing caravans or carrying maximum payload, inflate to 70-100 PSI for full support. This means you get factory-like ride quality when unloaded and firm, stable support when loaded — the best of both worlds. Keep a portable compressor in your vehicle or mount the inflation valves in an accessible location (rear bumper or wheel arch) for easy pressure adjustments at camp or the servo.
This airbag helper kit is designed to support loads and eliminate rear sag, but it does not provide additional lift height for fitting larger tyres — when inflated, it simply restores your vehicle to level ride height under load. If you want to fit larger tyres on your Landcruiser 100 Series, you'll need a proper suspension lift kit that raises the vehicle and provides additional clearance. Airbag helpers work perfectly in conjunction with lift kits — many customers install a 2-3 inch lift kit for tyre clearance and off-road capability, then add airbags for load-carrying and towing support. The airbags can be installed alongside most aftermarket suspension systems without issues.
AIRBAG MAN products are backed by comprehensive manufacturer warranty coverage, reflecting the brand's 25+ years of experience and commitment to quality. Specific warranty terms cover manufacturing defects in materials and workmanship for the airbags, fittings, and hardware components. Warranty coverage typically requires professional installation or competent DIY installation following the provided instructions, and excludes damage from vehicle accidents, improper installation, over-inflation beyond maximum PSI, or modification of components. Keep your proof of purchase and installation records for warranty claims. Contact our team or refer to the warranty information included with your kit for complete terms and conditions.
Absolutely — this AIRBAG MAN kit is designed for daily driving and excels in both urban and highway conditions. One of the major advantages is that you can adjust air pressure to suit your driving scenario: deflate for comfortable daily commuting with factory-like ride quality, then inflate when loading up for weekend trips or towing. The airbags provide excellent stability at highway speeds when towing caravans, reducing body roll and sway while improving driver confidence. Many Landcruiser 100 Series owners run low pressure (10-20 PSI) for daily driving to maintain comfort, then increase pressure as needed for loads. The system is fully road-legal in Australia and meets ADR compliance when installed correctly and operated within your vehicle's GVM limits.
