Airbag Man Air Suspension Helper Kit for Toyota Landcruiser 100 Series (1998-2007)

The Airbag Man CR5114HP High Pressure kit provides up to 2000kg combined load capacity when inflated to maximum pressure, significantly increasing your Landcruiser 100 Series' ability to handle heavy towing and payload. This additional support helps prevent rear sag when towing large caravans (up to 3500kg), carrying camper trailers, launching boats, or when the rear cargo area is loaded with camping gear, tools or equipment. The adjustable pressure system means you can dial in exactly the right amount of support for your current load - from minimal assistance for daily driving to maximum support for heavy towing applications. This prevents overloading your factory suspension and protects expensive components from premature wear.

This comprehensive kit includes everything needed for installation: two high-pressure airbags designed for rear axle fitment, laser-cut steel mounting brackets with corrosion-resistant finish, UV and abrasion-resistant nylon air lines, brass push-to-connect air fittings and connectors, external inflation valves for easy pressure adjustment, plus detailed step-by-step fitting instructions accessible via QR code. The only additional item you'll need is an air compressor for inflation - either a portable 12V unit or an onboard air system. All necessary hardware and fittings are included, eliminating the need to source additional components and ensuring a straightforward installation process with no surprises.

Absolutely - this high-pressure airbag kit is specifically designed for Australian towing conditions and heavy load applications. It excels when towing caravans, camper trailers, horse floats and boat trailers, eliminating the dangerous rear squat that affects braking performance, headlight aim and trailer stability. The kit prevents bottoming out on corrugated roads, maintains proper suspension geometry under load, and dramatically reduces trailer sway by keeping the rear of your vehicle level. Many Landcruiser owners use this kit for extended touring with roof-top tents, drawer systems, dual batteries, long-range tanks and recovery gear - the adjustable pressure means you can fine-tune support for any load combination from weekend camping trips to cross-country expeditions.

No, upgraded control arms are not required when installing airbag helper kits, as the airbags work alongside your existing factory suspension components rather than altering suspension geometry. However, if you're planning a comprehensive suspension upgrade or experiencing worn bushings, ball joints or control arm components, it's worth considering control arm upgrades at the same time to maximize handling and load performance. Many 100 Series owners combine airbag helpers with upgraded shock absorbers for the ultimate load-carrying and towing setup. The beauty of airbag helpers is they're a bolt-on addition that enhances your existing suspension without requiring extensive modifications or replacement of factory components, making them a cost-effective first step in improving load capacity.

Wheel alignment is not mandatory after installing airbag helper kits, as they don't alter your vehicle's suspension geometry or ride height when deflated - they simply provide additional support when inflated under load. Unlike lift kits or coil spring replacements that permanently change suspension angles, airbags are a progressive assistance system that only engages when you add air pressure. That said, if your 100 Series hasn't had an alignment check recently or you're experiencing uneven tire wear, it's always good practice to have alignment checked and adjusted as part of general maintenance. If you're installing this kit alongside other suspension modifications such as lift kits, new springs or control arms, then professional wheel alignment is definitely required to ensure optimal handling, tire life and steering performance.

Yes - adjustability is the key advantage of air suspension helper kits. You can adjust pressure from 5-100 PSI based on your current load, allowing you to run lower pressure (20-30 PSI) for daily driving and light loads, then increase to 60-80 PSI when towing your caravan or hauling heavy camping gear. The external inflation valves provide tool-free pressure adjustment in seconds using any standard air compressor or service station air line. This means you can optimize ride quality and load support for every trip - softer for unladen comfort, firmer for heavy towing stability. It's recommended to adjust pressure with the vehicle loaded to your typical touring weight, then fine-tune based on ride quality and whether the vehicle sits level front-to-rear.

This airbag helper kit does not provide suspension lift or increase ground clearance - it's designed to prevent sag and maintain factory ride height when carrying loads, not to accommodate larger tyres. If your goal is to fit larger diameter tyres (33" or bigger), you'll need a proper suspension lift kit that raises both front and rear suspension. However, airbag helpers are an excellent complement to a lift kit setup, providing adjustable rear support for towing and load carrying even after you've installed raised springs and shocks. Many 100 Series owners run airbag helpers alongside their lift kit to get the best of both worlds - increased ground clearance for bigger tyres and off-road capability, plus adjustable load support for touring and towing applications when the rear is heavily loaded.

Airbag Man products are backed by comprehensive manufacturer warranty coverage, reflecting the brand's confidence in their engineering and construction quality. Specific warranty terms cover defects in materials and workmanship, with the airbags themselves constructed from heavy-duty multi-ply reinforced rubber designed to withstand years of Australian conditions including UV exposure, road salt, mud and temperature extremes. To ensure your warranty remains valid, it's important to have the kit installed according to the provided instructions, maintain correct operating pressures (never exceed 100 PSI maximum), and use the system as designed for load support applications. For complete warranty details and claims procedures, contact 4WD Suspension Australia or refer to the documentation included with your kit.

This kit is perfect for daily driving AND heavy load applications - that's the beauty of adjustable air suspension. When running empty or with light loads, simply reduce air pressure to 10-20 PSI (or deflate completely) for comfortable daily driving with minimal impact on ride quality. When you load up for a weekend camping trip or hook up your caravan, increase pressure to restore level ride height and firm up the rear suspension for improved stability and control. Unlike heavy-duty coil springs that compromise unladen ride quality, airbags let you have both worlds - comfortable daily driving when empty, and firm load support when needed. Many 100 Series owners leave 20-30 PSI in the bags permanently to support常规 accessories like bull bars, roof racks and drawers, then increase pressure for towing.
