The beauty of air suspension helpers is infinite adjustability - set pressure according to your current load. For empty daily driving, run 5-10 PSI to maintain factory ride quality. When carrying camping gear, toolboxes or roof racks, increase to 15-20 PSI. For heavy towing applications with caravans or boat trailers, inflate to 25-35 PSI for maximum load support and leveling. Common rear loads affecting pressure requirements include bull bars, rear bars, dual battery systems, long range fuel tanks, drawer systems, roof top tents, water tanks, and full touring setups. Always measure vehicle height and adjust pressure gradually, checking level stance with load onboard.
This kit requires approximately 120 minutes installation time and is suitable for experienced DIY mechanics or professional workshop fitting. Drilling and cutting of mounting locations is required as specified in the detailed instructions. All necessary hardware and brackets are included in the kit. After installation, test inflate the airbags without load to check for leaks and confirm proper operation. We recommend pairing this system with upgraded shock absorbers if your factory shocks are worn, as this ensures optimal performance and ride quality under varying load conditions. An onboard air compressor provides convenient pressure adjustment on the trail.

This Airbag Man CR5038HP kit is specifically designed for Toyota 4Runner and Hilux Surf models from 1988 to 1997 (N130 series) equipped with coil spring rear suspension. It will not fit leaf spring variants or later model years with different rear suspension configurations. The kit requires drilling and cutting during installation to mount the airbags and brackets. If you're unsure about your specific vehicle's rear suspension type or have a different model year, please contact our team or check the parts finder on our website to confirm compatibility before ordering.
This high pressure system is adjustable from 5 to 35 PSI, providing progressive load support rather than a fixed weight increase. The actual load capacity depends on your existing suspension condition and vehicle specifications, but airbag helpers typically add 300-500kg of effective rear load support when inflated to maximum pressure. The key benefit is adjustability - you can run low pressure for comfortable empty driving and increase pressure progressively as you add cargo, camping gear or towing loads. This prevents rear sag and maintains level vehicle stance regardless of load variation, significantly improving safety and handling.
The complete kit includes two high pressure airbags rated to 35 PSI, heavy-duty mounting brackets and hardware, UV-resistant nylon airline tubing, inflation valves with dust caps, push-to-connect fittings, and all necessary fasteners. Detailed step-by-step installation instructions are provided with QR code access to digital guides and videos. The kit contains everything needed for installation except an air compressor - you'll need a portable tyre inflator or onboard air system to adjust pressure. All components are designed for Australian conditions with corrosion-resistant materials and UV-stable compounds.
Yes, this high pressure air suspension helper kit is excellent for towing applications and is widely used by caravan owners throughout Australia. When inflated to appropriate pressure (typically 25-35 PSI for heavy towing), the airbags eliminate rear sag caused by towball weight and significantly improve towing stability by reducing body roll and pitch. This maintains proper vehicle geometry, keeps headlights correctly aimed, and improves steering response and braking performance. Many 4Runner and Surf owners report dramatically improved towing confidence and reduced trailer sway after installing airbag helpers, especially when combined with quality shock absorbers and weight distribution hitches.
No, air suspension helper kits work with your existing control arms and do not typically require control arm upgrades. Airbags are supplementary devices that assist your factory coil springs rather than replacing suspension geometry components. However, if your 4Runner or Surf has worn or damaged control arms, bushes or ball joints, it's wise to address those issues during installation. Control arm upgrades become more important when installing lift kits that change suspension geometry, but for load-leveling airbag systems, they're not essential unless existing components are worn beyond serviceable limits.
A full wheel alignment is not typically required after installing air suspension helper kits, as they don't alter suspension geometry or mounting points in ways that affect alignment angles. However, it's good practice to check your alignment if you haven't done so recently, particularly if you're experiencing uneven tyre wear. The installation does require drilling and mounting brackets, so having alignment checked after fitment ensures everything is within specification. If you're installing this kit alongside other suspension modifications like lift kits or replacement springs, then a full four-wheel alignment becomes essential to ensure proper handling and tyre wear.
Yes, infinite adjustability is the primary advantage of air suspension helpers. You can adjust pressure in minutes using any air compressor to match your current load requirements. Run 5-10 PSI for comfortable empty daily driving, increase to 15-20 PSI for camping gear and accessories, and inflate to 25-35 PSI for heavy towing or maximum payload. Pressure adjustments require no tools - simply connect an air line to the inflation valves mounted in an accessible location (typically near the rear bumper or inside the cargo area). Many users install onboard air compressors for convenient adjustment on the road, allowing you to optimise ride quality and load support for every trip.
This airbag system does not provide suspension lift and therefore does not increase tyre clearance. Air suspension helpers work within your existing suspension travel to provide load support and leveling, but they don't raise the vehicle's ride height or create additional space for larger tyres. If you're looking to fit oversized tyres on your 4Runner or Surf, you'll need a dedicated lift kit with raised springs and potentially extended shock absorbers. However, airbag helpers are an excellent complement to lift kits, providing adjustable load support after the lift is installed. Many touring setups combine lift kits for tyre clearance with airbags for load management.
Airbag Man products are covered by comprehensive manufacturer warranty against defects in materials and workmanship. The specific warranty period and terms are detailed in the documentation included with your kit and available on the Airbag Man website. As with all suspension components, warranty coverage requires proper installation according to the provided instructions and normal use within the product's specifications (not exceeding maximum pressure ratings). Airbag Man has over 25 years of proven reliability in the Australian market with excellent warranty support. For specific warranty claims or questions, contact us and we'll coordinate with Airbag Man to ensure you're looked after.
Absolutely - one of the key benefits of air suspension helpers is that they don't compromise empty ride quality when properly adjusted. When running unladen or lightly loaded, simply deflate to 5-10 PSI and your 4Runner or Surf will drive virtually the same as factory. The airbags provide minimal resistance at low pressure, allowing your standard coil springs to function normally. You only inflate to higher pressures when carrying loads or towing. This makes the system perfect for vehicles that serve dual purposes - comfortable daily commuting during the week and heavy-duty touring or towing on weekends. Unlike fixed-rate heavy duty springs that are harsh when empty, airbags give you the best of both worlds.
