This Airbag Man kit is designed to support your vehicle's full payload capacity by adjusting air pressure to match your load. The beauty of airbag suspension is its infinite adjustability — simply increase pressure as you add weight. Common loads that benefit from air helper springs include slide-on campers, canopies with dual battery systems and fridges, roof-top tents, bull bars and rear bars with spare wheel carriers, water tanks, toolboxes, tow balls and weight distribution hitches when towing caravans or heavy trailers. Simply inflate to the pressure that restores level ride height — typically between 20-80 PSI depending on load.
This Airbag Man helper kit is designed for straightforward installation by experienced DIYers or professional workshops, typically completed in 2-3 hours. The airbags mount between your existing leaf springs and chassis using the supplied brackets and hardware — no welding or major modifications required. Inflation valves can be mounted in your rear bumper or wheel arch for easy access. While wheel alignment is not typically required for air helper springs (unlike suspension lift kits), it's recommended to check alignment if your vehicle has been sagging significantly. The system works in harmony with your factory suspension setup and can be paired with upgraded shock absorbers for even better performance when loaded.
Airbag Man has been Australia's leading air suspension specialist for over 25 years, with products proven across millions of kilometers of outback touring, daily tradework, and heavy towing applications. Every kit is engineered for Australian conditions and backed by exceptional customer service and technical support. The limited lifetime warranty on airbags demonstrates Airbag Man's confidence in their product quality and durability. Whether you're a tradie carrying tools and materials, a grey nomad towing a caravan around Australia, or a weekend warrior hauling boats and camping gear, Airbag Man delivers the load support and ride quality you need.
This air helper kit is ideal for Toyota 4Runner and Surf owners who regularly carry heavy loads or tow caravans, camper trailers, boats, or box trailers. It's particularly popular with tradespeople who need consistent load support for tools and equipment, touring families with loaded roof racks and rear cargo areas, and caravan owners who want to eliminate sag and maintain safe, level towing geometry. If you've noticed your rear end sitting low when loaded, headlights pointing skyward, or reduced stability and handling with weight in the back, this airbag suspension system is the solution.

This kit is specifically designed for Toyota 4Runner and Surf models from 1984 to 1997 that are equipped with rear leaf spring suspension (N60 and N130 series). It's essential to verify your vehicle has leaf springs at the rear, as some later models switched to coil spring suspension. If you're unsure about your specific vehicle's suspension type or have made modifications, our team can help confirm fitment — just contact us with your VIN or build details. The kit has been extensively tested on Australian-delivered 4Runner and Surf variants to ensure perfect compatibility.
Airbag Man air helper springs are designed to support your vehicle's full payload capacity as specified by the manufacturer. The system doesn't increase your legal payload limits, but it does help your suspension handle the rated load more effectively by preventing sag and maintaining level ride height. With adjustable pressure from 5 to 100 PSI, you can dial in the exact support needed for loads ranging from a few hundred kilograms to your maximum payload. The airbags work with your existing leaf springs to share the load, reducing stress on factory suspension components and improving stability, handling, and braking performance when carrying heavy cargo or towing.
This complete kit includes everything needed for installation: two heavy-duty air springs (5.5" - 6.5" height), all mounting brackets and hardware, stainless steel U-bolts, nylon air line tubing, fittings, and inflation valves with mounting hardware. You'll also receive detailed step-by-step fitting instructions accessible via QR code, plus an operation and maintenance manual. The only item not included is an air compressor — you can use a portable tire inflator, service station air, or upgrade to an onboard air compressor system for ultimate convenience. All components are engineered to work together as a complete system, eliminating the need to source additional parts separately.
Absolutely — this is one of the most popular applications for Airbag Man helper springs. When towing caravans, camper trailers, or boats, the rear of your 4Runner or Surf can sag significantly, causing poor headlight aim, reduced steering control, and unsafe handling characteristics. This air suspension system eliminates that sag by providing adjustable support that maintains level ride height regardless of tow ball weight. You'll experience improved stability, better weight distribution, reduced sway, and more confident braking performance. Many caravan owners run 40-60 PSI when towing and reduce pressure when unhitched for a comfortable unladen ride.
Air helper springs work with your existing suspension system, so additional upgrades aren't mandatory. However, many customers choose to pair this kit with upgraded shock absorbers for even better performance, especially if their factory shocks are worn or they're doing serious off-road touring. If your leaf springs are sagged, cracked, or worn out, consider replacing them as well to maximize the benefits of the air system. For vehicles with significant loads or heavy towing, upgraded shocks provide better damping control and work synergistically with the airbags. Our team can recommend complementary upgrades based on your specific usage requirements and budget.
Wheel alignment is typically not required after installing air helper springs, as they don't significantly alter your suspension geometry the way lift kits do. The airbags mount between your existing leaf springs and chassis without changing suspension arm angles or ride height when deflated. However, if your vehicle has been sagging badly for an extended period and you've been driving it that way, it's worth having alignment checked once the suspension is returned to proper ride height. This ensures even tire wear and optimal handling. Unlike major suspension modifications, air helpers are a bolt-on enhancement that works within your factory suspension design parameters.
Yes — infinite adjustability is the key advantage of air suspension systems. You can easily adjust pressure to match your exact load, from completely deflated (5 PSI) when running empty for best ride comfort, up to 100 PSI for maximum payload or towing capacity. Simply add or release air through the inflation valves using a tire inflator, air compressor, or service station air. Most users find their sweet spot between 20-80 PSI depending on load. The independent left and right airbags can also be adjusted separately to level side-to-side weight imbalances, perfect for boats on trailers or uneven cargo loads. This flexibility means you get optimal performance in every loading scenario.
When deflated or run at low pressure (5-10 PSI), Airbag Man helper springs have minimal impact on your unloaded ride quality. The airbags work in conjunction with your factory leaf springs rather than replacing them, so your original suspension characteristics are largely preserved when you're not carrying loads. Many owners run 5-15 PSI as a baseline even when empty to provide a slight firmness improvement without harshness. The system is designed to be infinitely adjustable, so you can find the perfect balance between comfort and support for any situation. This versatility means you don't have to compromise daily driving comfort for occasional load-carrying capability.
Airbag Man provides a limited lifetime manufacturer's warranty on the airbags themselves, demonstrating their confidence in product quality and durability. This industry-leading warranty coverage protects against manufacturing defects in materials and workmanship for the life of the airbags under normal use conditions. Other components in the kit are covered by standard manufacturer warranty periods. Airbag Man has been manufacturing air suspension systems in Australia for over 25 years and stands behind their products with excellent customer service and technical support. Always retain your proof of purchase and follow the installation and operation instructions to ensure warranty coverage remains valid.
This Airbag Man kit is designed for straightforward installation by mechanically competent DIY enthusiasts or professional workshops. The comprehensive instructions with diagrams make the process easy to follow, and no welding or specialized tools are required — just common hand tools. Most installers complete the job in 2-3 hours. The airbags mount between your leaf springs and chassis using the supplied brackets and hardware, and the inflation valves can be positioned in your rear bumper or wheel arch for convenient access. If you're comfortable with basic mechanical work like changing shocks or U-bolts, you can tackle this installation. Otherwise, any suspension shop or mechanic can easily fit the system using the detailed instructions provided.
Perfect for hauling tools and materials daily
Been running these airbag helpers on my Surf for about six months now and they've completely sorted out the sag when I'm loaded up with gear for work. The difference when towing my box trailer is night and day - much more level and stable on the highway. Installation was straightforward enough to knock over in the shed on a Saturday arvo, and the quality seems solid for the price point.(5)
Perfect for Our Loaded Family Camping Trips
Been running these air suspension helpers on the 4Runner for six months now and they've completely transformed how the truck handles when we're loaded up with camping gear, roof tent, and the kids' bikes. The difference in ride quality is night and day, especially on corrugated roads heading out to the high country. Installation was straightforward enough for a home mechanic, and being able to adjust the pressure depending on the load has been a game changer.(5)
Perfect for hauling tools and towing gear
Had these airbag helper springs fitted to my '95 Surf about three months back and they've been an absolute game changer. Carry a full load of tools and materials every day, and the rear end used to sag terribly, but now it sits level and handles way better even when fully loaded. Easy enough to adjust the pressure depending on what I'm carrying, and they've held up fine on some rough bush tracks out near the jobsites.(5)
Perfect for Our Loaded Family Camping Trips
These airbag helper springs have completely transformed how our 4Runner handles when we're loaded up for weekend trips down the coast. The back end no longer sags with the tent, water, and all the kids' gear, and the ride quality is noticeably smoother even on corrugated tracks. Installation was straightforward enough for a home job, and being able to adjust the pressure depending on the load is brilliant. Absolutely worth every cent for anyone who regularly tours with the family.(5)
