This high-pressure helper kit is designed for Jeep Wrangler JK owners who regularly carry heavy constant loads or tow substantial trailers. Consider your typical rear axle load including rooftop tents, rear bar and tyre carriers, dual battery systems, long-range fuel tanks, drawer systems, fridge slides, recovery gear, water tanks, and camping equipment. The high-pressure design provides maximum load support while maintaining ride quality—ideal for serious tourers who push their Wrangler's payload limits on extended trips.
This kit requires drilling for bracket mounting and is best installed by experienced DIY enthusiasts with fabrication skills or professional 4WD workshops—estimated installation time is 120 minutes. The airbags install inside your existing coil springs without removing suspension components, though access may require lifting the vehicle. After installation, inflate airbags to suit your load (start at 20 PSI unladen, adjust up to 80+ PSI when loaded). Optional in-cab inflation systems allow on-the-fly adjustment. For vehicles with raised suspension or modified geometry, consider pairing with upgraded shock absorbers for optimal performance and control.

This Airbag Man kit fits Jeep Wrangler JK (2007-2018) and select JL (2018-2023) models that have rear coil springs with 120mm internal diameter measured halfway down the coil. It suits both 2-door and 4-door variants including Sport, Overland, and Unlimited models. The kit is compatible with factory standard suspension, lowered setups, and raised aftermarket suspension configurations. However, not all JL models have 120mm ID coils, so it's essential to measure your coil spring diameter before ordering. If you're unsure about fitment, contact our team with your VIN number and we'll confirm compatibility for your specific Wrangler variant.
The Airbag Man High Pressure sleeve design doubles the lifting capacity of standard polyurethane airbags, providing up to 1,500kg of additional load support across the rear axle when inflated to maximum pressure. This makes it ideal for Jeep Wrangler JK owners carrying heavy constant loads like rooftop tents, rear bar and spare tyre carriers, drawer systems, dual batteries, long-range tanks, and recovery gear. The adjustable air pressure (5-100+ PSI) allows you to fine-tune support based on your current load—run lower pressure unladen for comfortable daily driving, then increase pressure when fully loaded for touring or towing. This prevents spring sag, maintains ride height, and ensures your Wrangler's suspension geometry stays within safe operating parameters regardless of payload.
The complete kit includes 2 x Firestone high-pressure polyurethane airbags with protective sleeves, mounting brackets and all necessary hardware (drilling required), high-grade UV-resistant nylon air line tubing, brass air fittings, inflation valves, and comprehensive fitting instructions with QR code access to online manuals. The airbags come with Firestone's lifetime manufacturer warranty. Please note that air compressors and optional in-cab inflation control systems are sold separately—we recommend adding these accessories for convenient on-the-fly pressure adjustment. The kit contains everything needed for a complete rear axle airbag installation, and the step-by-step instructions make the process straightforward for experienced DIY installers or professional workshops.
Absolutely—this high-pressure helper kit is specifically designed for heavy towing applications and is one of the most popular upgrades for Jeep Wrangler JK owners towing caravans, camper trailers, or boat trailers up to 3,500kg. The adjustable airbags eliminate rear-end sag, maintain level ride height, improve weight distribution across all four tyres, and dramatically reduce dangerous body roll during cornering and emergency maneuvers. This results in better steering control, safer braking, reduced understeer, and more predictable handling when towing. You'll also experience less wear on rear suspension components and more even tyre wear. The ability to adjust air pressure means you can run lower pressure when not towing for comfortable daily driving, then increase to 60-80+ PSI when hitched up for maximum stability and control.
This airbag helper kit works with your existing factory or aftermarket control arms and doesn't require control arm upgrades for installation. However, if you're running a raised suspension setup (lift kit) or have modified your Wrangler's suspension geometry, upgraded adjustable control arms can help maintain optimal alignment angles and improve overall handling. Many serious tourers choose to combine airbag helper kits with quality control arm upgrades to maximize suspension performance, especially when carrying constant heavy loads or towing regularly. The airbags provide load support and ride height control, while upgraded control arms maintain proper suspension geometry throughout the travel range. If you're unsure whether your setup would benefit from control arm upgrades, our suspension experts can assess your specific configuration and recommend the best combination for your touring needs.
No, wheel alignment is typically not required after installing this airbag helper kit because the airbags sit inside your existing coil springs and don't alter suspension geometry or mounting points. Unlike lift kits that change ride height and suspension angles, this system simply provides additional load support through adjustable air pressure. However, if you notice uneven tyre wear, steering pull, or if you're installing the airbags as part of a broader suspension upgrade that includes new springs, shocks, or lift components, then a professional wheel alignment is strongly recommended. It's always good practice to have your alignment checked periodically anyway, especially on heavily loaded touring vehicles. Proper alignment ensures optimal tyre life, predictable handling, and safe braking performance on both highway and off-road conditions.
Yes—adjustable air pressure is the primary benefit of this system and allows you to perfectly tune rear suspension support for any load condition. When unladen or lightly loaded, run 5-20 PSI for comfortable daily driving with minimal impact on ride quality. When carrying camping gear, touring accessories, or medium loads, increase to 30-50 PSI. For maximum loads or when towing heavy caravans and camper trailers, inflate to 60-100+ PSI for optimal support and stability. The high-pressure sleeve design allows safe operation at higher pressures than standard airbags, providing greater lifting capacity when needed. Many Wrangler owners add an optional in-cab inflation system with dual gauges, allowing convenient pressure adjustment from the driver's seat without needing to exit the vehicle—perfect for changing conditions on extended outback trips.
This airbag helper kit doesn't provide suspension lift for fitting larger tyres—it's designed to prevent spring sag and maintain your current ride height when loaded, not to increase ground clearance for bigger rubber. If your goal is to fit larger tyres (33", 35", or bigger), you'll need a proper suspension lift kit that raises your Jeep Wrangler's overall height and provides clearance in the wheel arches, guards, and suspension travel zones. However, if you already have a lift kit installed and are experiencing rear sag due to heavy accessories and touring gear, this airbag system is the perfect complement—it maintains your lifted height under load and prevents the saggy rear-end look common on heavily equipped Wranglers.

This kit includes Firestone airbags backed by a lifetime manufacturer warranty, covering defects in materials and workmanship for as long as you own your vehicle. This industry-leading warranty demonstrates the exceptional quality and durability of Firestone polyurethane airbags, which are proven across millions of kilometres on Australian roads. The warranty covers the airbags themselves—mounting hardware, air lines, and fittings carry standard manufacturer warranties. Airbag Man has been Australia's leading air suspension specialist for over 25 years with a reputation for standing behind their products. To maintain warranty coverage, follow the installation instructions, perform regular visual inspections for damage or wear, and ensure airbag pressures stay within recommended ranges. If you experience any issues, our Australian-based support team will assist with warranty claims and replacement parts.
Yes, this kit is excellent for daily driving and highway use—in fact, most Airbag Man customers use their systems every day with outstanding results. When unladen, simply reduce air pressure to 5-10 PSI (or completely deflate if preferred) and your Wrangler will drive exactly as it did before installation, with factory ride quality maintained. The beauty of adjustable air suspension is versatility—comfortable and compliant for your daily commute, then firm and supportive when loaded for weekend trips or long-distance touring. The high-pressure polyurethane construction is extremely durable and requires minimal maintenance beyond periodic visual inspections. Unlike some aftermarket suspension modifications that compromise on-road comfort, this helper kit system enhances your Wrangler's capability without sacrificing daily drivability. It's the perfect solution for vehicles that need to perform dual duties as both comfortable daily drivers and serious touring platforms.
Perfect for Our Loaded Family Camping Trips
These Airbag Man helper springs have been a game changer for our Wrangler when we head out bush with the family. Previously the rear would sag pretty badly with all our camping gear, the kids, and the rooftop tent loaded up. The difference in ride quality is night and day - the JK sits level now and handles so much better on corrugated tracks, plus installation was straightforward enough to do at home.(5)
Perfect for the daily work rig
Been running these Airbag Man helper springs on my JK for about 6 months now and they've been brilliant. Load up the tray with tools and materials every day, and the rear end stays level instead of sagging like it used to. Easy enough to adjust the pressure depending on what I'm carrying, and they've handled some rough tracks on weekend trips without any dramas.(5)
Perfect Solution for Our Loaded Family Trips
Been running these Airbag Man helper springs on our JK Wrangler for six months now and they've completely transformed how the rig handles when we're packed up for camping. The rear end used to sag terribly with all our gear, water, and the kids' stuff, but now it sits level and the ride quality is actually better than empty. Really impressed with how easy they were to adjust for different loads, and fitment was spot on with no dramas during installation.(5)
