This is an adjustable air helper kit rather than a fixed spring rate product, so instead of choosing a spring rate you choose an air pressure to suit your load. Run 5-10 PSI for an empty or lightly loaded 4Runner/Surf, and wind up toward 35 PSI when you're carrying a full camping setup, tow ball weight, or tray accessories. Common accessories that push you toward the higher end of the PSI range include caravans and camper trailers, rooftop tents, long-range fuel tanks, and tray-mounted tool boxes or water tanks.
Fitment is a straightforward bolt-in job for an experienced DIY installer with basic hand tools, or your usual suspension workshop, and typically takes under an hour per side. Because this kit doesn't change your static unladen ride height, a full wheel alignment isn't mandatory the way it is with raised coil springs — but it's worth a quick check if you run higher PSI settings for extended touring or towing. If you're also fitting a lift kit or raised coil springs alongside this helper kit, pair it with upgraded control arms to keep suspension geometry correct at the new ride height. Always check air line routing clears moving suspension components before you drive away.
Airbag Man has been designing and testing air suspension helper kits in Australia for more than 25 years, with this CR5038HP kit built specifically around the coil spring rear end of the 1988-1997 4Runner and Surf. Every kit is backed by a manufacturer's warranty, and our team can talk you through PSI settings for your specific load before you fit it. View the full Airbag Man range if you're also considering a lift kit alongside this helper kit.
This kit suits owners who regularly carry weight in the back of their 4Runner or Surf — tradespeople with tools and equipment, tourers running camper trailers or roof-top tents, and anyone towing a caravan who wants the rear end to sit level rather than sag. If your loads vary a lot trip to trip, an airbag suspension helper like this gives you more flexibility than a fixed heavy-duty spring alone.
Ready to stop rear sag on your 4Runner or Surf? This CR5038HP kit is dispatched from Australian stock with support from our fitment team, and you can also browse our full suspension components range if you need shocks, springs or control arms to go with it.
This CR5038HP kit fits Toyota 4Runner and Surf models from 1988 to 1997 that have factory coil spring rear suspension. Leaf spring rear variants need a different Airbag Man kit, so it's worth checking your rear suspension type before ordering. If you're not sure which setup your vehicle has, contact our team with your build date and we can confirm fitment before you buy.
This is a load-support helper kit, not a lift kit, so it doesn't add static ride height when unladen. At 5 PSI it sits passively without altering ride height, and winding up toward 35 PSI firms the rear to counteract sag under load rather than raising the vehicle permanently. If you want an actual static lift as well, pair this kit with raised coil springs from our coil springs range.
The CR5038HP kit includes 2 x Airbag Man High Pressure air springs, upper and lower mounting brackets, chrome-plated inflation valves, braided air line and fittings, and all mounting hardware. Fitting instructions are included in the box. It's designed to bolt in around your existing coil spring rear suspension without cutting or permanent modification.
Yes, this is exactly what the High Pressure version is built for. Running higher PSI settings while towing a caravan or camper trailer counteracts tow ball weight and stops the rear from sagging, which helps keep headlights aimed correctly and the vehicle sitting level. Drop back to a lower PSI once you unhook to restore the softer unladen ride.
Not for this helper kit on its own, because it doesn't change your static unladen ride height or suspension geometry. Control arm upgrades become relevant if you also fit a lift kit or raised coil springs at the same time, since those genuinely change ride height and alignment angles. If you're combining this kit with a lift, our team can advise on matching control arms.
A full wheel alignment isn't mandatory after fitting this kit on its own, since unladen ride height doesn't change. It's still worth a quick alignment check if you regularly run higher PSI settings for extended towing or touring, as sustained load can subtly affect ride attitude. If this kit is fitted alongside a lift kit or new coil springs, an alignment is required.
This kit doesn't work on selectable spring rates like a coil spring upgrade does — instead you select an air pressure between 5 and 35 PSI to match your load. Lower PSI suits an empty or lightly loaded vehicle, while higher PSI suits full camping gear, a loaded tray, or a caravan on the tow ball. If you want a fixed heavier spring rate instead, look at our coil springs range for load-rated options.
Because this kit doesn't raise ride height, tyre clearance stays the same as factory. If you're planning to run larger tyres, you'll need an actual lift kit with raised coil springs rather than this helper kit alone. Our team can help you plan a lift kit and tyre combination that works together for your 4Runner or Surf.
This CR5038HP kit is backed by Airbag Man's manufacturer warranty, reflecting more than 25 years of the brand building air helper kits for Australian conditions. Exact warranty terms and claim details are available from our team on request. We also provide fitment support if you have any questions before or after installation.
Yes, that's how it's designed to work. Run it around 5 PSI for daily driving to keep the factory-soft unladen ride, then increase pressure only when you're carrying extra load or towing. Because the air springs sit passively at low PSI, they don't harshen the ride during normal commuting.
