The Airbag Man Helper Kit CR5107 fits inside the factory or aftermarket coil spring on a Jeep Wrangler JK (2007-2023), 2-door and 4-door, covering Sport, Overland and Unlimited variants. Each Firestone-sourced airbag adjusts from 0 up to 100psi, so you add load support only when carrying touring gear, a bullbar or a trailer — not when running empty. It sits alongside your existing suspension setup without altering unloaded ride height or geometry. Backed by Firestone's lifetime warranty on the airbags, dispatched from Australian stock, with fitment guidance available via our JK parts finder.

Because this kit uses adjustable air pressure rather than a fixed spring rate, you match psi to your constant accessory load instead of ordering a specific rated coil. Common front loads include a steel bullbar, winch and driving lights, while rear loads typically come from drawers, a canopy, water tanks, camping gear or a loaded roof rack. Start with lower pressure for daily driving and increase toward the 100psi ceiling only when the vehicle is loaded for touring or towing.
Fitting the airbags inside the coil spring perimeter is a straightforward DIY job for an experienced installer, though we recommend professional fitment if you're not confident working around suspension components. Because the kit only adds support when inflated, unloaded ride height and factory alignment settings are not changed by the airbags themselves. If you're running higher constant pressure for regular towing, it's worth having your alignment checked afterwards. If you're also correcting geometry from a lift, pair this kit with upgraded control arms for a properly set-up front end.
Airbag Man builds its air springs around Firestone rubber, the same manufacturer supplying air suspension components globally, and backs the airbags with a lifetime warranty. The brand is a regular fitment for Australian tourers and tradespeople who need adjustable load support rather than a fixed spring rate. You can view the full Airbag Man range for other JK-compatible suspension upgrades.
This kit suits JK owners who regularly carry or tow a variable load — trades vehicles running tool storage and equipment, and tourers packing camping gear, water and recovery kit for weekends away. If you're after adjustable airbag suspension rather than a fixed heavier spring, this helper kit lets you dial support up or down as your load changes trip to trip.

The CR5107 Helper Kit is built to fit inside the coil spring perimeter on Jeep Wrangler JK models from 2007 to 2023, covering both 2-door and 4-door body styles including Sport, Overland and Unlimited variants. It's designed to work with factory-height coil springs as well as raised coils from an existing lift kit. If you're running a non-standard coil spring or aftermarket bracket setup, contact our team to confirm bracket compatibility before ordering.
This is a load-support helper kit, not a lift kit — it doesn't add a fixed lift height. The airbags sit inside the coil spring and only take up load when inflated, so your unloaded ride height stays as it is now, whether that's factory or an existing lift. If you want a genuine ride height increase on top of load support, pair this kit with a set of raised coil springs from our range.
The kit includes two Firestone-sourced air springs, top mounting brackets, lower locating cups, a nylon air line kit with fittings, and two chassis-mounted inflation valves. A T-piece is included where dual-point inflation is fitted. An air gauge and 12V compressor are not included and are sold separately.
Yes, that's a primary use case. Increasing air pressure toward the 100psi ceiling adds support to the coil spring when you're hitched up or carrying a loaded canopy, then you can drop pressure back down for unladen daily driving. This gives you variable support rather than a single fixed spring rate for all conditions.
Not specifically for this helper kit, since it doesn't change your ride height or suspension geometry on its own. If your JK already runs a taller lift with raised coil springs, upgraded control arms may still be worth fitting to correct caster and driveline angles at that height — that's separate to whether you run this airbag kit.
Fitting the airbags themselves doesn't require an alignment, as unloaded ride height and geometry are unchanged. If you regularly run higher constant air pressure for towing, it's good practice to have your alignment checked afterwards, particularly if it's combined with an aftermarket lift kit already on the vehicle.
This kit doesn't use a fixed spring rate — it uses adjustable air pressure from 0 up to 100psi, which you set based on your accessory and towing load. That means one kit covers a range of load scenarios instead of needing a different-rated spring for light versus heavy use.
Because this is a load-support kit rather than a height-increasing lift kit, it won't create extra tyre clearance on its own. If you're planning larger tyres, you'll need a genuine lift kit with raised coil springs; this helper kit can then be run alongside that lift for added load support.
The air springs are backed by Firestone's lifetime manufacturer warranty, covering the rubber airbag component. Brackets and fittings are covered under standard supplier terms. Keep your invoice from 4WD Suspension as proof of purchase for any warranty claim.
Yes. Run the airbags at low or zero psi for unloaded daily driving so the ride stays as it was before fitment, then increase pressure only when you're carrying extra weight. This on/off flexibility is the main advantage over a fixed heavier-rated coil spring that stays stiff all the time.
