The beauty of air helper kits is their infinite adjustability - you simply adjust air pressure to match your current load requirements. Start with 20-30 PSI for moderate loads and increase up to 100 PSI for maximum load support. Common accessories that benefit from air helper support include roof racks with rooftop tents, rear tire carriers, heavy-duty rear bumpers with dual jerry can holders, drawer systems, fridges, water tanks, recovery gear, and camping equipment. For Wrangler owners who frequently tow camper trailers or boat trailers, maintaining 50-70 PSI helps prevent rear sag and maintains proper trailer tongue weight distribution.
This Airbag Man helper kit is designed for straightforward installation by experienced DIYers or professional workshops, with an estimated fitting time of approximately 120 minutes. The kit includes comprehensive step-by-step instructions accessible via QR code, along with all necessary brackets, hardware, air lines, and fittings. Drilling is required to mount the airbag brackets to the chassis, so take care to measure twice and drill once. The inflation valves can be mounted in a convenient location such as inside the rear cargo area or underneath the vehicle for easy access. While this helper kit works with existing shock absorbers and springs, it's recommended to inspect all suspension components during installation and replace any worn bushings or hardware for optimal performance.

This CR5107 helper kit fits Jeep Wrangler JK models from 2007-2018 (2-door and 4-door Sport, Overland, and Unlimited variants) and select JL models from 2018-2023. The critical fitment requirement is coil spring inner diameter - your coils must measure 100-105mm ID when measured halfway down the coil. It's compatible with factory standard suspension and raised aftermarket coil springs that fall within this diameter range. If you've installed a lift kit with larger diameter coils, please measure carefully or contact us to confirm fitment before ordering.
The Airbag Man helper kit provides infinitely adjustable load support from 0-100 PSI, effectively adding several hundred kilograms of load-carrying capability to your Wrangler's rear suspension. The exact weight capacity depends on your existing springs and vehicle configuration, but most Wrangler owners find 50-70 PSI provides excellent support for heavy camping gear and towing, while 80-100 PSI handles maximum loads including caravans and fully loaded rear cargo areas. The beauty of air suspension is you can adjust pressure to match your specific load - run low pressure when empty for comfortable riding, then inflate when loaded.
This complete kit includes everything needed for installation: two Firestone airbags with lifetime warranty, heavy-duty mounting brackets and all necessary hardware, high-pressure nylon air lines and fittings, inflation valves for pressure adjustment, and comprehensive installation instructions with QR code access to digital guides. The kit also includes an operation and maintenance manual to help you get the most from your new air suspension system. The only additional items you'll need are basic hand tools and a drill for mounting the brackets - no welding or specialized equipment required.
Absolutely - this helper kit is specifically designed to improve towing performance and safety. When towing a camper trailer, boat trailer, or caravan, the added weight on the rear of your Wrangler can cause dangerous spring sag that affects steering, braking, and stability. The Airbag Man system eliminates this sag by providing adjustable support that maintains proper ride height and suspension geometry. This keeps your headlights aimed correctly, improves weight distribution across all four tyres, reduces trailer sway, and makes towing significantly safer and more controlled, especially on long highway trips or corrugated outback roads.
No, this airbag helper kit works with your existing suspension components including springs, shocks, and control arms - no additional upgrades are mandatory. However, it's a good opportunity to inspect all suspension components during installation and replace any worn bushings, shock absorbers, or steering components. If you're running a lifted Wrangler JK, you may already have upgraded control arms to correct castor angle. The airbag kit doesn't change your suspension geometry, so whatever control arm setup you currently have will continue to work perfectly. We recommend having your suspension inspected by a professional if you haven't done so recently.
No, wheel alignment is not required after installing this airbag helper kit because it doesn't change your suspension geometry or ride height - it simply provides additional load support within your existing suspension travel. The airbags work alongside your factory or aftermarket coil springs without altering castor, camber, or toe settings. However, if you notice uneven tyre wear or steering pull during or after installation, it's worth having your alignment checked, as these symptoms may indicate pre-existing issues that were masked before. It's always good practice to have alignment checked annually or after any significant suspension work regardless.
You can easily adjust air pressure yourself using any standard tyre pump, air compressor, or even a service station air line - no special equipment needed. The kit includes inflation valves that can be mounted in a convenient location like the rear cargo area or underneath the vehicle for easy access. Simply connect your air line, inflate to the desired pressure (typically 20-100 PSI depending on load), and check with a standard tyre pressure gauge. Many Wrangler owners keep a small 12V compressor onboard for convenience, allowing them to adjust pressure on the trail or before heading home from a camping trip.
This helper kit doesn't provide lift height for larger tyres - it maintains your existing ride height while providing additional load support. If you're looking to fit larger tyres, you'll need a proper suspension lift kit that increases ground clearance and provides room in the wheel arches. However, this airbag helper kit is an excellent complement to existing lift kits, as it prevents the rear-end sag that often occurs when running heavy wheels and tyres plus camping gear. If you've already installed a lift kit and are experiencing spring sag under load, this helper kit solves that problem perfectly without needing stiffer springs that compromise unladen ride quality.
The Firestone airbags included in this kit are backed by a comprehensive lifetime manufacturer warranty, demonstrating the exceptional quality and durability of these components. This warranty covers manufacturing defects and premature failure under normal use conditions. The mounting hardware, air lines, and fittings carry standard manufacturer warranty coverage. Airbag Man has been supporting Australian customers for over 25 years with industry-leading customer service and warranty support. Keep your receipt and installation documentation, and if you ever experience issues, contact us or Airbag Man directly for prompt warranty assessment and replacement if required.
Yes, that's one of the key advantages of air suspension over heavy-duty springs - adjustability for every situation. When you're not carrying heavy loads or towing, simply deflate the airbags to 0-10 PSI (or completely deflate them) and your Wrangler will ride just like it did before installation, using only the factory or aftermarket coil springs. When you load up for a trip or hook up a trailer, inflate the airbags to the appropriate pressure for that load. This gives you the best of both worlds: comfortable daily driving without the harsh ride of heavy-duty springs, plus serious load support when you need it for weekend adventures or work duties.
Perfect for our loaded up family trips
These helper bags have been a game changer for our monthly camping trips down the coast. The JK was sagging noticeably with the rooftop tent, kids' gear, and all our camping equipment, 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. Well worth the investment for anyone who regularly loads up their Wrangler.(5)
Perfect for My Work Rig
Been running these airbag helpers on my JK for about 6 months now and they've been absolutely brilliant. Haul tools and materials every day, and the difference when loaded is night and day - no more sagging rear end and way more stable on the highway. Installation was pretty straightforward too, had them in within a few hours. Well worth the money for anyone using their Wrangler as a daily work horse.(5)
Perfect for Our Loaded Family Camping Trips
These airbag helper springs have been a game changer for our JK when we load up the kids and camping gear for weekend trips. The rear end used to sag quite a bit with the rooftop tent and all our equipment, but now it sits level and the ride quality is so much better, even on corrugated tracks. Installation was straightforward enough to tackle in the driveway, and being able to adjust the pressure for different loads is brilliant.(5)
