The Airbag Man Full Air Suspension Kit replaces the rear coil springs on your Jeep Gladiator JT (2018-On) with commercial-grade Firestone air springs, giving you 0-2" of infinitely adjustable ride height. Air pressure control eliminates spring sag under load, so your Gladiator sits level whether towing a caravan or running empty. This metric tubing kit suits factory height, lowered, or raised setups and works with all suspension parts for the Gladiator JT in our range. Backed by Firestone's lifetime warranty, in stock in Australia, with fitment support from our team.

Because this is an air spring system rather than a fixed-rate steel coil, you don't select a spring rate at purchase — you set it with air pressure once fitted, firming up for load and dropping it for an unladen ride. Consider your typical constant accessory load before ordering an air controller: canopies, drawer systems, dual batteries, water tanks, rooftop tents and caravan ball weight all affect how much pressure you'll run day to day. Heavier constant loads generally mean you'll sit at higher base pressure to keep the Gladiator level.
Installation takes around 180 minutes for an experienced DIY mechanic with basic tools, though professional fitting is recommended given the air line routing and axle-mounted brackets involved. Wheel alignment is recommended after fitting and again once you've settled on a regular ride height, since any change in rear height affects rear geometry slightly. On-board air controls are required for in-cab adjustment and are sold separately. If you're also running a front lift, pairing this kit with upgraded control arms helps keep castor within range front to rear.
Airbag Man has engineered air suspension for Australian vehicles and conditions for over 25 years, with kits designed around local towing and touring use rather than generic overseas fitments. This kit uses genuine Firestone air springs backed by a lifetime manufacturer's warranty, and is supported by our range of suspension components if you need matching hardware down the track. It's a system used by tradespeople running constant tool and canopy loads as much as tourers towing off-road.
This kit suits Gladiator JT owners who tow caravans or camper trailers regularly, run a canopy and drawer system for work, or carry rooftop tents and camping gear on tour. If load levelling and adjustable clearance matter more than a fixed lift height, this airbag suspension system gives you that control without swapping coil springs for different jobs.

Yes, the OA6049M kit is designed specifically for the Jeep Gladiator JT built from 2018 onwards, covering both 3.6L Pentastar V6 and 3.0L EcoDiesel V6 variants. It replaces the factory rear coil springs with Firestone air springs matched to the JT's rear axle and chassis mounting points. If you run a modified rear bar or aftermarket chassis accessories, contact our team to confirm fitment before ordering.
The system is adjustable from fully lowered to 2" raised, controlled entirely by air pressure rather than a fixed spring height. This lets you lower the Gladiator for easier loading or raise it up to 2" for extra clearance on tracks or when towing. Ride height is adjusted in real time via on-board air controls, which are sold separately to this kit.
The kit includes two Firestone air springs for the rear axle, mounting hardware, metric nylon air lines, quick-connect fittings and step-by-step instructions accessible via QR code. On-board air control panels, gauges and compressors are not included and are sold separately. Everything needed to mount the air springs in place of the factory coil springs is supplied.
Yes, it's built with towing in mind. Maintaining constant air pressure prevents the rear squat that occurs with sagging factory coils under trailer ball weight, keeping the tow coupling level and reducing sway at highway speed. It also keeps headlight aim and brake bias correct when hitched up, which factory springs can't do once they've started to sag.
Most Gladiator JT owners running this air suspension kit at factory height or up to 2" raised don't need control arm changes. If you've also fitted a front lift kit that pushes castor angle out of range, upgraded control arms can help correct geometry — it's worth checking with our team based on your full setup.
Yes. Any change in ride height, including running the air springs raised, alters castor and camber slightly, so a wheel alignment is recommended after installation and again once you've settled on your preferred ride height. This protects tyre wear and keeps steering feel consistent.
This is an air spring system, not a fixed-rate steel spring, so rate isn't chosen at purchase — it's tuned with air pressure once fitted. You add pressure to firm up the rear for towing or heavy accessories, and reduce it for an unladen, comfortable ride. This gives more flexibility than selecting a single fixed spring rate upfront.
Running the air springs at their maximum 2" raised setting adds extra clearance in the rear guards, which can help with slightly larger tyres depending on your Gladiator's wheel offset and any front-end lift already fitted. Check actual clearance with wheels on and full-lock steering before committing to a tyre size change.
The Firestone air springs included in this kit carry the manufacturer's lifetime warranty. 4WD Suspension also provides fitment support Australia-wide, and genuine Airbag Man parts are backed by the brand's dealer network for ongoing service and spares.
Yes. You can run the air springs at a lower pressure for a comfortable daily ride and increase pressure only when loaded or towing, unlike fixed heavy-duty springs that feel firm even unladen. This adjustability is one of the main reasons Gladiator owners choose air suspension over a fixed helper spring kit.
