The Airbag Man Helper Kit for Coil Springs fits Jeep Wrangler JK 2-door and 4-door models — Sport, Overland and Unlimited — from 2007 to 2023, and works with standard, lowered or raised suspension up to a 4" lift. Two Firestone-manufactured air bladders sit inside your factory coil springs, giving adjustable air pressure to correct sag and hold ride height under a heavier rear load. It pairs well with our coil spring range if you're planning a further upgrade. Backed by Firestone's lifetime warranty, in stock in Australia now with fitment support from our team.

This helper kit doesn't run a fixed spring rate like a heavy-duty coil — you tune it with air pressure to suit the load on the day. Run low pressure, or leave it empty, for unladen driving and wind pressure up before towing a van or loading gear. Common accessories that add constant rear load on a JK include steel rear bars, long-range fuel tanks, drawer systems, dual battery trays and roof-top tents — if several of these are fitted permanently, keep a higher baseline pressure as your default setting.
Fitting the Airbag Man Helper Kit means removing the factory coil spring, inserting the air bladder into the spring's centre, then reinstalling the spring with the supplied mounting cups and air line. Most experienced DIY installers can handle it with basic hand tools and a spring compressor, though we recommend a qualified workshop if you haven't compressed coil springs before. Wheel alignment isn't typically needed for a helper kit fitted at standard ride height, but get it checked if you're combining this with a control arm upgrade or raised springs. Recheck the air line fittings for leak-down after the first 500km on the road.
Airbag Man has developed air suspension products for Australian 4WDs and light commercials for over 25 years, with kits designed for local towing and touring conditions. The air bladder in this kit carries Firestone's lifetime warranty, and 4WD Suspension backs the whole kit with fitment support from our Australian team. Tradespeople, tourers and van-towers around the country run Airbag Man helper kits as a straightforward fix for rear sag — view the full Airbag Man range for other JK-specific options.
This kit suits Wrangler JK owners carrying a consistent rear load — tradies with tools and gear, tourers running a rear bar, fridge slide and water tanks, and anyone towing a box trailer or camper. If your JK sags at the back with gear loaded and sits level when empty, that's exactly the problem this airbag suspension kit is built to fix.
The Airbag Man Helper Kit for Jeep Wrangler JK is in stock in Australia and ships from local stock with fitment support from our suspension team — check all suspension parts for the Wrangler or browse our full lift kit range if you're planning a raised-suspension build too.

Yes — this Airbag Man Helper Kit is built for JK 2-door and 4-door Unlimited models, across Sport and Overland trims, model years 2007 to 2023. It fits vehicles running standard-height coil springs and those lifted up to a 4" lift. If you're running a lift beyond that, or non-standard coils, get in touch with our team to confirm fitment before you order. You can also check compatibility using our parts finder for the Wrangler.
This is a load-support helper kit, not a lift kit — it doesn't raise ride height on its own. It sits inside your existing coil springs, whether they're standard, lowered, or already raised up to about a 4" lift, and adds adjustable air pressure to correct sag under load. If you're after actual lift height, look at our coil spring or lift kit range and add this helper kit alongside it for extra load support. Our team can help you combine both correctly.
The kit includes 2 x Airbag Man air bags with the Firestone air bladder, 2 x upper mounting cups, 2 x lower locating saddles, a braided air line kit with T-piece, quick-connect fittings, Schrader-style inflation valves, mounting hardware and fitting instructions. Coil springs themselves are not included — the air bladder fits inside your existing factory or aftermarket coil spring. Everything needed to plumb one or two inflation points is supplied. Full details are listed in the kit contents above.
Yes, that's one of its main uses. Winding up the air pressure before you hook up a van or trailer corrects the rear sag a loaded tow causes, keeping the JK level and steering feel consistent. You can drop the pressure back down for unladen driving once the trip is done. It's a genuinely adjustable setup rather than a fixed heavy-duty spring rate.
Not for this helper kit on its own, since it doesn't change ride height at standard settings. If you combine it with raised coil springs or a lift kit, upgraded control arms help correct suspension geometry and driveline angles at the new height. We'd recommend checking our control arm range if you're planning a raised-suspension build alongside this kit. Our team can advise based on your exact combination.
Generally no, if the vehicle is at standard ride height, since the helper kit doesn't alter geometry on its own. If you're fitting it alongside raised coil springs or a lift kit, we recommend a wheel alignment once everything is installed and settled. Get the alignment checked again after towing a heavy load for the first time, since ride height will vary with air pressure. When in doubt, book an alignment as cheap insurance.
This kit doesn't use a fixed spring rate the way a heavy-duty coil does — instead, you adjust air pressure in the bladder to suit the load on the day. Run it near empty for unladen driving and increase pressure before towing or loading up. That flexibility is the main advantage over swapping in a single heavier-rated coil spring. If you'd prefer a fixed higher-rate coil instead, our coil spring range has options too.
Since this is a load-support helper kit rather than a lift kit, tyre clearance stays the same as your current suspension setup. If your JK already runs a lift kit up to around a 4" lift, this kit works alongside that without affecting clearance further. For extra tyre clearance on its own, you'll want to look at our lift kit range rather than this helper kit. Talk to our team if you're planning both together.
The air bladder in this kit is covered by Firestone's lifetime manufacturer warranty. 4WD Suspension also backs the kit with fitment support from our Australian-based team if you run into any installation questions. Keep your proof of purchase for any warranty claim. Reach out to our team if you notice any air loss or fitting issues after installation.
Yes. Run the bags at low or minimal pressure for everyday unladen driving, which keeps ride quality close to standard, then increase pressure only when you're loaded up or towing. This on-demand adjustability is what makes it practical for daily drivers that occasionally carry a heavier load. There's no compromise to everyday comfort since you control the support level yourself.
