Airbag Man helper kits allow infinite adjustment between 5-100 PSI to match your specific load requirements. Start with 10-15 PSI for unladen driving to maintain factory ride quality. For light loads such as camping gear and recovery equipment, increase pressure to 20-35 PSI. Medium loads including rooftop tents, water tanks and dual battery setups typically require 40-60 PSI. Heavy loads such as towing camper trailers, caravans up to 2500kg ATM, or vehicles fitted with slide-on campers may need 65-100 PSI. Always measure vehicle stance and adjust pressure incrementally to achieve level ride height. Common rear accessories affecting air pressure requirements include: bull bars and winches (weight transferred rearward during hill climbs), long-range fuel tanks, dual spare wheel carriers, rear drawer systems, fridges and camping equipment, rooftop tents, awnings, water tanks, and tow-ball weight from trailers or caravans.
Professional installation is recommended, though experienced DIY mechanics with appropriate tools can complete fitment in approximately 120 minutes. Drilling is required to mount the airbag brackets to the chassis, so accuracy and proper placement are critical. The kit includes comprehensive step-by-step instructions accessible via QR code or the Airbag Man website. Vehicle must be level and properly supported on jack stands throughout the installation process. After installation, conduct a thorough safety inspection of all mounting points, air line connections and inflation valves before loading the vehicle. Wheel alignment is not typically required for helper kit installation unless you're also upgrading to lift kits or suspension components. We recommend pairing this airbag kit with quality shock absorbers for optimal load-carrying performance.

This CR5104 helper kit fits Jeep Wrangler JK (2007-2018) and JL (2018-2023) models in both 2-door and 4-door Unlimited configurations, including Sport, Overland and Rubicon variants. The critical requirement is that your coil springs must have a 120mm internal diameter when measured at the midpoint of the coil. This kit suits standard factory suspension, lowered setups, and raised aftermarket suspension configurations as long as the coil ID specification is met. If you're unsure about your coil spring diameter or have aftermarket springs fitted, contact our team for fitment verification before ordering.
Airbag Man helper kits don't technically increase your vehicle's GVM (Gross Vehicle Mass) or legal load rating, but they restore your suspension's ability to handle loads up to the manufacturer's specified limits without sagging. The CR5104 kit provides adjustable support from 5-100 PSI, allowing you to eliminate rear squat when carrying heavy camping gear, rooftop tents, or towing camper trailers and caravans. Most Wrangler owners find this kit easily handles tow-ball weights up to 350kg and rear cargo loads that would otherwise cause significant suspension sag. Always stay within your vehicle's published GVM and towing capacity limits regardless of suspension upgrades fitted.
The complete kit includes 2 Firestone air helper springs with lifetime warranty, internal jounce bumpers for overload protection, mounting brackets and hardware, nylon air line tubing, push-to-connect fittings, Schrader inflation valves, and detailed installation instructions with QR code access. Everything required for installation is supplied except basic hand tools. The kit is designed as a complete bolt-in solution, though drilling is required for mounting bracket installation. You can inflate the airbags manually using a tyre pump, or upgrade to an in-cab inflation system or on-board air compressor for convenient adjustment on the go.
Yes, the Airbag Man CR5104 is excellent for towing applications, helping to eliminate rear squat caused by tow-ball weight and improving overall towing stability and safety. By maintaining proper vehicle stance when hitched, the kit ensures your headlights remain properly aimed, steering remains responsive, and weight distribution stays optimal for safer braking and handling. Most Wrangler owners towing camper trailers or compact caravans run 50-80 PSI depending on tow-ball weight. The adjustable nature means you can fine-tune pressure to achieve perfect level stance regardless of your specific trailer weight, then deflate for improved ride quality when driving unladen.
No, control arm upgrades are not required when installing airbag helper kits, as these work with your existing suspension geometry and don't change ride height like lift kits do. The CR5104 simply provides additional support to your existing coil springs without altering suspension geometry or requiring castor correction. However, if you're also planning to install a lift kit or have worn factory control arms, upgrading to adjustable aftermarket control arms is recommended for optimal suspension geometry and alignment settings. Airbag helper kits can be fitted independently or as part of a larger suspension upgrade strategy depending on your specific requirements and driving conditions.
Wheel alignment is typically not required after installing airbag helper kits, as they don't alter your suspension geometry or ride height in the same way lift kits do. The airbags work in conjunction with your existing coil springs without changing control arm angles or castor settings. However, if you notice uneven tyre wear, steering pull, or if you're installing this kit as part of a larger suspension upgrade that includes lift components, a professional four-wheel alignment is recommended. It's always good practice to have alignment checked annually or after any significant suspension work to ensure optimal tyre life and handling characteristics.
Yes, infinite adjustability is one of the key benefits of the Airbag Man system - you can adjust air pressure anywhere from 5 to 100 PSI to match your exact load requirements. For unladen daily driving, run 10-15 PSI to maintain factory ride quality. Increase pressure to 30-50 PSI for camping gear and equipment, 50-70 PSI for rooftop tents and heavy cargo, or 70-100 PSI when towing caravans or carrying maximum loads. The kit includes Schrader valves that can be inflated using a standard tyre pump, service station air, or you can upgrade to wireless in-cab controllers or on-board air compressor systems for convenient adjustment without leaving the driver's seat.
The Airbag Man CR5104 helper kit doesn't provide suspension lift, so it won't increase tyre clearance for larger diameter tyres. This is a load-support system that works with your existing suspension height, whether factory standard, lowered, or already lifted. If you want to fit larger tyres on your Wrangler JK or JL, you'll need a proper suspension lift kit to increase clearance. However, the airbag kit is an excellent complement to lifted Wranglers, as the additional weight of larger tyres, heavier wheels, and off-road accessories often causes rear sag that airbags effectively eliminate. Many Wrangler owners install both lift kits and airbag helpers for the ultimate touring and load-carrying setup.
The Firestone airbags included in this kit are backed by a lifetime manufacturer's warranty against defects in materials and workmanship, providing exceptional long-term value and peace of mind. This lifetime coverage demonstrates Firestone's confidence in their industrial-grade air spring technology and construction quality. Other kit components including mounting hardware, air lines and fittings are covered by Airbag Man's standard warranty terms. Warranty coverage requires proper installation according to the supplied instructions and normal use within the product's specifications. For full warranty terms and conditions or to make a warranty claim, contact 4WD Suspension Australia or refer to the documentation included with your kit.
Absolutely - the Airbag Man CR5104 is ideal for daily driving, particularly if you regularly carry loads or experience suspension sag from fitted accessories like bull bars, roof racks, and drawer systems. Many Wrangler owners run 10-20 PSI for daily driving to maintain factory ride quality while preventing the gradual sag that occurs with constant accessory weight. The system is completely adjustable, so you can increase pressure for weekend camping trips or towing, then deflate for comfortable empty driving during the week. The result is improved ride comfort, better steering response, more even tyre wear, and enhanced safety compared to running on sagging factory springs. Thousands of Australian tradies and daily drivers rely on Airbag Man systems for year-round comfort and capability.
Perfect for Remote Touring with Heavy Gear
Been running these airbag helpers on my JK through the Simpson Desert and Cape York, and they've completely transformed how the Jeep handles a full load of recovery gear, water, and camping equipment. The adjustability means I can fine-tune the rear suspension depending on whether I'm solo or loaded up for a month-long trip. Installation was straightforward enough to do in the driveway, and the ride quality remains excellent even when carrying serious weight on corrugated tracks.(5)
Perfect for Our Loaded Family Camping Trips
These Airbag Man helper springs have completely transformed how our JK handles when we're loaded up for weekend trips away. Previously the rear would sag badly with all our camping gear, fridge and water, but now it sits level and the ride quality is actually better than empty. Installation was straightforward enough for a home job, and the adjustability means I can fine-tune it depending on the load. Couldn't be happier with how the Jeep tows our camper trailer now.(5)
Best upgrade I've made to the JK
Chuck these airbag helpers on my Wrangler about three months back and they've been brilliant for carting tools and materials around every day. The difference when I'm loaded up is night and day - no more sagging in the rear and the ride stays level even with a full load of pavers or timber. Fitted up pretty straightforward too, took me and a mate a couple hours on the weekend.(5)
Perfect for Our Loaded Family Camping Trips
These airbag helper kits have completely transformed how our JK handles when we're loaded up with kids, camping gear and the rooftop tent for weekend trips. The rear end no longer sags, and the ride quality actually improved compared to the overloaded standard coils we were running before. Installation was straightforward enough to tackle in the driveway, and being able to adjust the pressure for different loads is brilliant.(5)
