The Airbag Man CR5049HP requires drilling and cutting for proper fitment on both Landcruiser 80 and 300 Series models.

The kit includes comprehensive step-by-step instructions accessible via QR code, with detailed diagrams showing mounting locations, bracket placement, and air line routing. While experienced DIY installers with appropriate tools can complete the installation, ensuring correct airbag alignment and secure bracket mounting is critical for safe operation and long-term durability.

Yes, the CR5049HP is specifically engineered for Toyota Landcruiser 80 Series models (FJ80, FZJ80, HDJ80, HZJ80) manufactured from August 1991 to 1998, and Landcruiser 300 Series models from 2021 to 2024. This high-pressure kit is designed for coil spring rear suspension configurations and is fully compatible with E-KDSS (Electronic Kinetic Dynamic Suspension System) equipped 300 Series variants. The kit requires some drilling and cutting during installation to accommodate mounting brackets. If you're unsure about your specific model, contact our team with your VIN number for confirmation.
When fully inflated, the Airbag Man CR5049HP can support up to 1,400kg of additional rear axle load, making it ideal for towing heavy caravans, carrying slide-on campers, or hauling significant payload. The high-pressure design allows inflation from as low as 5 PSI for light loads up to 100+ PSI for maximum support. This adjustability means you can fine-tune the air pressure to match your exact load requirements — whether it's an empty vehicle, moderate camping gear, or a fully-loaded touring setup with caravan attached. The airbags work in conjunction with your existing coil springs to share the load rather than replace them entirely.
The complete kit includes two high-pressure airbag assemblies designed for coil spring applications, nylon air line tubing with quick-connect fittings, stainless steel mounting brackets and all necessary hardware, and remote inflation valves for easy pressure adjustment. You'll also receive comprehensive fitting instructions accessible via QR code and a detailed operation manual. The kit contains everything needed for installation except an air compressor — we recommend adding an in-vehicle inflation kit or portable compressor for convenient on-the-road pressure adjustments. All components are manufactured to withstand harsh Australian conditions including corrugations, salt spray, and extreme temperatures.
Absolutely — this is one of the primary applications for the Airbag Man CR5049HP. The kit dramatically improves towing stability by eliminating rear sag, reducing body roll during cornering, and maintaining proper vehicle geometry under heavy towball loads. When towing caravans, boat trailers, or horse floats, the airbags keep your Landcruiser level, which improves headlight aim, braking performance, and overall handling safety. The adjustable pressure allows you to dial in the perfect support for different trailer weights, and the dual airbag setup enables side-to-side levelling if your load distribution isn't perfectly balanced. Many long-distance tourers consider airbags essential equipment for safe caravan towing.
The Airbag Man CR5049HP is designed as a helper spring system that works with your existing suspension components including factory or aftermarket coil springs and shock absorbers. You don't need to upgrade control arms specifically for the airbag installation. However, if you're also planning to fit a suspension lift kit or have worn suspension bushes, it's an ideal time to consider upgraded components as part of a complete suspension overhaul. Pairing quality shock absorbers with your airbag system will further enhance ride quality and load-carrying capability. Our team can recommend complementary upgrades based on your specific vehicle usage and budget.
A full four-wheel alignment check is recommended after installation, though the airbag kit itself doesn't typically alter suspension geometry as dramatically as a lift kit would. The installation process involves drilling and mounting brackets which could potentially affect rear axle positioning slightly. More importantly, when you inflate the airbags to support heavy loads, this can change your vehicle's ride height and alter alignment angles. Having a professional alignment ensures your Landcruiser tracks straight, tyres wear evenly, and handling remains predictable under both laden and unladen conditions. Most professional installers include an alignment check as part of the fitment service.
Yes — adjustability is the key benefit of the Airbag Man system. You can inflate the airbags anywhere from 5 PSI for minimal support (when driving unladen) up to 100+ PSI for maximum load-carrying capacity. The remote inflation valves are mounted in accessible locations, allowing you to adjust pressure in minutes without tools or crawling under the vehicle. For example, you might run 10-15 PSI for daily driving, increase to 40-50 PSI when carrying camping gear, and inflate to 70-80 PSI when towing your caravan. Each side can be adjusted independently for uneven loads. We recommend adding an in-vehicle compressor or quality portable unit for convenient pressure changes on the road.
The Airbag Man CR5049HP is a load-support system rather than a lift kit, so it doesn't significantly increase ground clearance or create additional tyre clearance. While inflating the airbags will raise the rear of your vehicle when under load (bringing it back to level), this is designed to restore factory ride height rather than exceed it. If you want to fit larger tyres, you'll need a proper suspension lift kit that includes raised coil springs, extended shock absorbers, and potentially other components. The airbag kit can be used in conjunction with a lift kit to handle the extra weight of larger tyres and wheels while maintaining the benefits of adjustable load support.
Airbag Man products are backed by comprehensive manufacturer warranty coverage, reflecting the brand's confidence in their Australian-engineered components and construction quality. The warranty covers manufacturing defects in materials and workmanship under normal operating conditions. Specific warranty duration and terms are detailed in the product documentation included with your kit and available on the Airbag Man website. To ensure warranty validity, we recommend professional installation by a qualified mechanic and following all operation guidelines regarding maximum pressure and load limits. Keep your purchase receipt and installation records for warranty claims. Our team can assist with any warranty questions or claims processing.
Yes, the Airbag Man CR5049HP is perfectly suited for daily driving when properly adjusted. When your Landcruiser is unladen or lightly loaded, simply reduce the air pressure to 5-15 PSI (or completely deflate) to maintain your factory ride quality and comfort. The airbags add minimal harshness when running low pressure, allowing normal suspension articulation over bumps and road irregularities. When you load up for weekend trips or hook up the caravan, increase pressure to match your load and enjoy level, stable handling. This versatility makes airbag systems ideal for vehicles that serve dual purposes — daily commuting during the week and heavy towing or touring on weekends. Thousands of Australian Landcruiser owners rely on Airbag Man systems for exactly this use case.
