Adjust airbag pressure based on your loaded weight. Start with 20-30 PSI for light loads (roof rack, camping gear), increase to 40-60 PSI for medium loads (dual batteries, fridge, recovery gear), and run 70-100 PSI for heavy towing or full expedition setups with rooftop tents and rear drawers. Always measure your ride height when loaded and adjust pressure to restore factory stance — this ensures optimal suspension geometry, steering feel, and headlight aim. Check pressure monthly and before long trips, as temperature changes affect PSI.
This kit requires drilling into chassis or spring mount points and is best installed by a qualified mechanic or experienced DIY enthusiast with proper tools and vehicle lifting equipment. Installation typically takes around 120 minutes for both sides. The airbags fit inside the existing coil springs, with mounting brackets securing top and bottom points. After installation, inflate airbags to 20 PSI as a baseline, then adjust according to load. While wheel alignment is not mandatory for airbag helper kits, it's recommended if you've also installed suspension lift kits or notice uneven tyre wear. Pairing this system with upgraded suspension components maximises performance and longevity.

This kit suits all Jeep Wrangler JL models (2018-2023) including 2-door Sport, 4-door Unlimited, and Overland variants, provided your rear coil springs have an internal diameter of 100-105mm measured halfway down the coil. It's compatible with factory suspension and most aftermarket lifted setups. If you've installed a lift kit or aren't sure of your coil ID, measure with callipers or contact our team for confirmation before ordering.
While airbag helper kits don't technically increase your vehicle's GVM (Gross Vehicle Mass), they restore suspension performance and ride height when carrying loads up to your manufacturer's rated capacity. The adjustable air pressure (5-100 PSI) allows you to compensate for varying weights, preventing sag and maintaining optimal suspension geometry. This effectively allows you to carry heavy camping gear, rooftop tents, or tow trailers safely without bottoming out or losing steering control.
The kit includes 2 Firestone airbags designed to fit inside your coil springs, all necessary mounting brackets and hardware, nylon air line tubing, fittings, inflation valves, and comprehensive installation instructions with QR code access to online guides. Everything required for installation is provided except tools and a method of inflation. You'll need a portable air compressor, service station air, or an optional onboard compressor system to adjust airbag pressure as needed.
Absolutely — this is one of the most popular upgrades for Wrangler JL owners who tow. The airbags eliminate rear-end sag caused by towball weight, improve weight distribution across all four tyres, and reduce dangerous sway and porpoising at highway speeds. By maintaining level ride height, your headlights stay properly aimed, steering remains responsive, and braking performance is optimised. Inflate to higher pressures (60-100 PSI) when towing, then deflate for unladen driving comfort.
No, airbag helper kits work within your existing suspension setup and don't require control arm upgrades for installation. However, if you've also installed a suspension lift kit or are experiencing steering wander and poor handling, upgraded control arms can further improve suspension geometry and alignment. Airbags address load carrying and sag, while control arms address geometry and articulation — they complement each other but aren't interdependent for this kit specifically.
Wheel alignment is not typically required after installing airbag helper kits, as they don't alter suspension geometry or mounting points in the way lift kits do. However, if you notice uneven tyre wear, steering pull, or have recently installed other suspension modifications, an alignment is good practice. The airbags simply support the existing springs and can be inflated or deflated without affecting toe, camber, or caster settings on your Wrangler JL.
Yes, that's the key benefit of this system — you have complete control over pressure adjustment to suit your load. Each airbag has an accessible inflation valve (similar to a tyre valve) that you can adjust using a portable compressor, service station air, or dedicated onboard system. Simply check your ride height when loaded, and add or release air until the vehicle sits level. Most users keep a small compressor or tyre gauge in the vehicle for on-the-go adjustments during touring trips.
Airbag helper kits are designed to restore and maintain factory ride height under load — they don't provide suspension lift for larger tyres on their own. If you inflate the airbags to maximum pressure unladen, you may gain 10-20mm of additional height, but this is not their intended purpose and will result in a harsh ride. For larger tyres, you'll need a dedicated suspension lift kit with raised springs and longer shocks, which can then be paired with airbags for load support and adjustability.
The Firestone airbags included in this kit are backed by a lifetime manufacturer's warranty against defects in materials and workmanship — one of the best warranties in the industry. This covers the airbag membranes themselves under normal use conditions. Mounting hardware, air lines, and fittings carry a standard 12-month warranty. Airbag Man's 25-year reputation in Australia and comprehensive support network ensure you're covered for the long haul, whether you're touring the Kimberley or commuting daily.
Yes, the Airbag Man helper kit is excellent for daily driving, especially if you regularly carry tools, equipment, or family gear that causes rear sag. When unladen, simply deflate the airbags to 5-10 PSI or even zero for a comfortable factory-like ride. When loaded, inflate as needed to restore level stance. This adjustability makes it perfect for tradies who load up during the week and tour on weekends, or families who switch between school runs and caravan holidays without compromising ride quality in either scenario.
Game changer for my work setup
Been running these airbag helpers on my JL for about 6 months now and they've absolutely sorted out the sag issues I had with all my tools and gear in the back. The difference when towing the work trailer is night and day - no more bottoming out on rough tracks heading to job sites. Installation was pretty straightforward too, took me a Sunday arvo in the shed with a mate.(5)
Sorted the Sag on My Loaded JL
These helper airbags have been a game-changer for my heavily loaded Wrangler on remote Simpson Desert and Canning Stock Route trips. The adjustability means I can run them softer for solo trips and pump them up when carrying extra fuel, water, and recovery gear without that awful coil spring sag. Fitment was straightforward and the ride quality improvement when loaded is immediately noticeable—no more bottoming out on whoops or corrugations. Well worth the investment for anyone doing serious touring.(5)
Perfect for Loading Up the Family Camper
These airbag helper springs have been a game changer for our monthly camping trips down the coast. The JL was sagging noticeably with the camper trailer, kids, and all our gear loaded up, but now it sits level and handles so much better on the highway. Installation was straightforward enough to do in the driveway over a Saturday morning. Definitely worth it if you're serious about touring with a loaded rig.(5)
Perfect for Daily Work and Weekend Adventures
Been running these airbag helpers on my JL for about six months now and they've completely sorted the sag when I'm loaded up with tools and equipment during the week. The ride quality is noticeably better even when I'm not carrying a full load, and they handled a Cape York trip without any dramas. Installation was straightforward enough for a weekend job, and the build quality feels properly solid.(5)
Perfect for Our Loaded Family Camping Trips
These airbag helper springs have completely transformed how our Wrangler handles when we're loaded up with the camper trailer, kids, and all the camping gear. The difference in rear-end sag is night and day, and the adjustability means I can fine-tune it depending on what we're carrying. Installation was straightforward enough for a home job, and the ride quality is so much better on corrugated dirt roads now. Highly recommend for anyone doing serious touring with their JL.(5)
