The Airbag Man High Pressure Helper Kit is a coil-spring air support system purpose-built for Jeep Wrangler JL models running 100-105mm ID coil springs. Rather than replacing the spring, this airbag suspension fits inside the existing coil and lets you wind pressure up under a heavy load or back it off for an unladen ride. It counters sag from bull bars, canopies, drawers and touring gear, holding ride height steady as load changes. Backed by a lifetime manufacturer's warranty, in stock in Australia now.

This kit doesn't change your coil spring rate — instead you adjust air pressure in the bags to match your constant accessory load. Wind more pressure in for permanent fitments like bull bars, winches, canopies or drawer systems, and run lower pressure when the vehicle is empty for a softer ride. If your JL carries a roof-top tent, long-range fuel tank or a heavy canopy full-time, set your base pressure around that load and adjust up only when towing on top of it.
Fitment involves compressing the coil spring to insert the air bag, so we recommend a professional installer or an experienced DIY fitter with the right spring compressor tools. Because this kit doesn't change ride height at factory pressure, a wheel alignment isn't mandatory — but check ride height once loaded and get the geometry checked if you notice any change. Allow the air bags to settle over the first 500km of driving before locking in your day-to-day pressure setting. If you're also chasing a height increase, pair this kit with our upgraded control arms range for corrected geometry.
Airbag Man design and test their air bag systems in Australia for local conditions, from outback touring tracks to daily tradie loads. Every kit carries a lifetime manufacturer's warranty on the air bag components, and our team can talk you through pressure settings for your specific JL setup. Explore the full Airbag Man range to see helper kits, full replacement bags and matching suspension components.
This kit suits JL owners running heavier rear-end accessories — canopies, drawer systems, dual battery setups or a caravan on the tow ball — who need to keep ride height and handling consistent under variable load. Tourers and tradespeople who load and unload regularly benefit most from the on-the-fly adjustability. If you're chasing a fully adjustable airbag suspension setup for constant heavy loads, this is a straightforward way to add support without a full spring swap.

This helper kit fits Jeep Wrangler JL models running coil springs with a 100-105mm internal diameter (ID), covering standard Sport, Sahara and Rubicon variants from 2018-ON. If your JL has been fitted with aftermarket coils outside this ID range, check the spring diameter before ordering. Our team can confirm fitment against your specific coil spring if you're unsure. Reach out via our contact page or use the parts finder for the Wrangler JL.
This is a helper kit, not a lift kit, so it's not designed to permanently raise ride height. It sits inside the existing coil spring and adds adjustable air support to counter sag under load, keeping ride height consistent rather than increasing it. If you're after an actual height increase, look at Airbag Man's dedicated suspension lift kit range instead. This product is about load control, not ground clearance gain.
The kit includes two Airbag Man High Pressure air bags sized for 100-105mm ID coil springs, two chassis-mounted inflation valves, air line hose, a T-piece fitting and mounting hardware. Fitting instructions are supplied in the box. An air compressor and pressure gauge are not included and need to be sourced separately for air-up.
Yes, it's specifically designed to control coil sag when towing or carrying a constant accessory load such as a canopy, drawer system or caravan on the tow ball. You increase air pressure in the bags to add support when hitched up, then reduce pressure again once unhitched. This makes it a practical add-on for JL owners who tow regularly but don't want a permanent spring rate change.
Not necessarily, because this kit doesn't change your JL's ride height at factory air pressure, so suspension geometry stays close to standard. If you're running this alongside a lifted suspension setup, upgraded control arms help maintain correct alignment and driveline angles at height. Talk to our team about your full setup so we can advise on control arms if needed.
Wheel alignment isn't mandatory for this kit alone since it doesn't raise ride height at standard pressure. That said, it's worth checking ride height once the vehicle is loaded and getting an alignment done if you notice any change in geometry. If this kit is fitted alongside a lift kit, alignment after install is required regardless.
This kit doesn't replace your coil spring or change its fixed spring rate — it adds adjustable air pressure inside the existing coil instead. You fine-tune support by winding pressure up or down through the inflation valve to suit your current load, rather than selecting a different spring rate product. This gives you a range of support levels from one kit rather than a single fixed setting.
Since this is a helper kit and not a height-increasing lift kit, it won't create the extra clearance needed for larger tyres on its own. Tyre fitment on your JL stays governed by your current suspension setup and wheel arch clearance. If bigger tyres are the goal, pair this kit with an Airbag Man lift kit designed to raise ride height.
The Airbag Man air bag components in this kit are backed by a lifetime manufacturer's warranty. This covers the air bags against manufacturing defects for as long as you own the product. Keep your proof of purchase from 4WD Suspension for any warranty claim, and our team can help process it if needed.
Yes, it's built for everyday use on a JL that regularly switches between empty and loaded conditions. Run lower air pressure for a softer, factory-like ride when unladen, and increase pressure when carrying gear, towing or touring. It's a straightforward system to adjust from the driver's seat without any tools once it's fitted.
