Airbag pressure should be adjusted based on your actual rear axle load, not a fixed PSI rating. Start with 20 PSI minimum for airbag protection when unladen, then increase pressure incrementally as you add weight until the vehicle sits level at factory ride height. Common rear loads include bullbars, dual spare wheels, long-range fuel tanks, drawer systems, fridges, rooftop tents, water tanks, recovery gear, and tow ball weight from caravans or trailers. For optimal performance, measure your rear axle height unladen and loaded, then adjust airbag pressure to maintain consistent height regardless of load.
Professional installation is recommended, though experienced DIY installers with workshop facilities can complete fitment in approximately 120 minutes. This kit requires drilling for mounting bracket installation to achieve secure attachment points on the Landcruiser 100 Series chassis. After installation, inflate airbags to 20 PSI minimum to protect against rubbing, then adjust pressure according to load as outlined in the included operation manual. While wheel alignment is not typically required for airbag helper kit installation (unlike suspension lift kits), it's recommended to verify alignment if you experience uneven tyre wear or steering pull after fitment.

This Airbag Man CR5050HP kit is specifically designed for Toyota Landcruiser 100 Series (HDJ100, HDJ101R, UZJ100) and 105 Series (FZJ105, HZJ105) models manufactured between 1998-2007 with coil spring rear suspension. It fits both IFS (Independent Front Suspension) and solid axle variants. The kit includes vehicle-specific mounting brackets and all necessary hardware for proper fitment. If you have aftermarket suspension modifications or non-standard chassis alterations, please contact us to verify compatibility before ordering.
The Airbag Man High Pressure system delivers up to 2800kg combined load support across both airbags when inflated to the maximum 100 PSI working pressure. This makes it ideal for heavy caravan towing (including large tandem-axle vans), fully loaded touring setups, and commercial applications. The adjustable pressure range from 20-100 PSI allows you to precisely match support to your actual load, from light recreational use to maximum capacity towing. Load capacity should always be considered within your vehicle's GVM (Gross Vehicle Mass) and rear axle rating limits.
This complete kit includes everything required for installation: 2 high-pressure airbags rated to 100 PSI, vehicle-specific mounting brackets and hardware, nylon airline tubing with push-fit connectors, inflation valves with dust caps, stainless steel fasteners, and comprehensive fitting instructions accessible via QR code. All components are designed to work together as an integrated system, eliminating the need to source additional parts. The kit does require some drilling for bracket installation to the Landcruiser 100 Series chassis. No compressor is included, but airbags can be inflated using any portable 12V compressor, service station air, or hand pump.
Absolutely — this high-pressure airbag system is specifically engineered for heavy towing applications including large caravans, camper trailers, and boat trailers. By maintaining level ride height under tow ball load, the kit dramatically improves towing stability, reduces trailer sway, maintains correct headlight aim, and prevents rear suspension bottoming on corrugated roads. The adjustable pressure capability means you can inflate to match your specific caravan's tow ball weight (typically 200-350kg), then deflate when driving solo for comfortable unladen ride quality. Many Landcruiser owners towing tandem-axle vans over 2500kg rely on airbag systems as essential safety equipment.
No, airbag helper kits work with your existing suspension components including factory or aftermarket control arms, and do not require control arm upgrades for fitment. Unlike suspension lift kits that alter suspension geometry and may benefit from extended control arms, airbag systems are designed to support load while maintaining factory suspension positioning. However, if your Landcruiser 100 Series has worn control arm bushes or ball joints showing play, it's wise to address these wear items during any suspension work. Airbags complement rather than replace quality suspension components, working best when your entire suspension system is in good condition.
Wheel alignment is not typically required after installing airbag helper springs, as they work within your existing suspension geometry without altering control arm angles or suspension mounting points like lift kits do. The airbags simply provide variable rate support to your coil springs without changing suspension geometry. However, it's always good practice to verify your alignment if you notice uneven tyre wear, steering pull, or if your vehicle hasn't had an alignment check in the past 12 months. Most Landcruiser owners can fit this kit without subsequent alignment, but professional inspection is recommended if you have any handling concerns post-installation.
Yes, one of the key advantages of Airbag Man systems is the ability to adjust pressure at any time, loaded or unloaded. The inflation valves are mounted in an accessible location, typically inside the rear bumper area or near the chassis, allowing you to add or release air in minutes using a portable compressor, service station air, or even a hand pump. Many tourers and towers adjust pressure based on changing loads throughout their trip — inflating before hitching the caravan or loading gear, then deflating for unladen driving. Always maintain minimum 20 PSI when deflated to protect the airbags from rubbing or damage.
When properly adjusted, this airbag helper kit actually improves ride quality across all load conditions. When driving unladen, deflate the airbags to the minimum 20 PSI and your factory coil springs provide their normal comfortable ride characteristics — the airbags simply act as a passive helper with minimal effect. Under load, inflating the airbags prevents rear sag and suspension compression, which actually restores the factory-designed ride quality and handling characteristics that would otherwise be compromised by heavy weight. Unlike stiff constant-rate heavy-duty springs that punish you when empty, airbags offer the best of both worlds: soft when light, firm when loaded.
Airbag Man provides comprehensive warranty coverage on all components in this kit, reflecting their confidence in product quality and durability proven over 25+ years in the Australian market. The airbags themselves are covered against manufacturing defects in materials and workmanship, while fittings, hardware, and brackets are similarly warranted. Warranty coverage requires proper installation according to the provided instructions and normal use within the product's specified pressure and load ratings. As an authorised Airbag Man dealer, 4WD Suspension Australia provides full warranty support and can assist with any product issues. Retain your purchase receipt and installation documentation for warranty claims.
Yes, this system is ideal for both daily driving and extended touring applications across all Australian conditions. When used as a daily driver without heavy loads, simply maintain 20-30 PSI for normal comfortable ride quality with the added security of load support on demand. For touring, the system excels — allowing you to carry heavy rear loads (roof tents, jerry cans, dual batteries, fridges) while maintaining stable handling and ride height. The high-pressure capacity makes it particularly suitable for long-distance caravan touring where consistent load support over thousands of kilometres is essential. Australian tourers rely on Airbag Man systems across the Nullarbor, Cape York, and Outback tracks with proven reliability.
