Adjust air pressure based on your specific load requirements — from 5 PSI for light loads up to maximum rated pressure for heavy hauling. For typical touring setups with roof racks, dual battery systems, and camping equipment, start at 20-30 PSI and adjust until the vehicle sits level. When towing caravans or camper trailers, increase pressure incrementally until rear sag is eliminated and the vehicle maintains factory rake angle. Always inflate equally side-to-side to prevent uneven loading.
This Airbag Man helper kit requires approximately 120 minutes for installation by experienced DIY enthusiasts or professional workshop fitment. Drilling is necessary to mount the airbag brackets to the chassis, and basic hand tools are required throughout the process. The kit includes comprehensive step-by-step instructions accessible via QR code, with detailed diagrams for bracket positioning and air line routing. For vehicles with significant lift or modified suspension geometry, consider pairing this kit with upgraded control arms to maintain optimal suspension geometry and driveline angles. After installation, check all fittings for air leaks and test inflate to ensure proper operation before loading the vehicle.

This kit is specifically designed to suit Jeep Wrangler JK 2-door and 4-door models from 2007-2018, including Sport, Overland, and Unlimited variants. It's also compatible with select JL models from 2018-2023. The kit works with both factory standard coil springs (CR5063 for 140mm ID) and lifted suspensions up to 96mm (CR5100 option). If you've installed aftermarket lift kits or modified your suspension, confirm your coil spring internal diameter and lift height before ordering to ensure correct fitment.
The CR5063 is designed for standard factory coil springs with 140mm internal diameter, while the CR5100 is specifically engineered for vehicles with 96mm lifted suspension setups. Both options are also available in high-pressure (HP) variants for increased load capacity. Choose based on your current suspension configuration — if you're running a lift kit, the CR5100 is typically the correct choice. Standard height Wranglers should use the CR5063 option for proper fitment and optimal airbag performance.
While exact load capacity varies based on air pressure and vehicle configuration, this Airbag Man helper kit significantly increases your Wrangler's ability to carry heavy loads without sagging. The adjustable air pressure allows you to match support levels to your specific load — from light camping gear to maximum towing capacity. Most users experience elimination of rear-end sag when towing caravans up to 2500kg ATM, carrying heavy roof loads, or running constant accessory weight like dual batteries and long-range tanks. Adjust pressure incrementally until the vehicle sits level under load.
Absolutely — this is one of the primary applications for Airbag Man helper kits. The adjustable air suspension maintains proper ride height and reduces rear-end sag when towing, which improves steering response, braking performance, and headlight aim. It also reduces stress on your factory coil springs and shock absorbers during long-distance touring. The kit stabilises body roll and sway when towing in crosswinds or on corrugated roads, delivering a safer and more comfortable towing experience for both short trips and extended outback adventures.
The Airbag Man helper kit does not require control arm upgrades for installation or operation, as it works within your existing suspension geometry to provide load support. However, if your Wrangler JK already has a significant lift kit (over 50mm), upgraded control arms may be beneficial for maintaining proper suspension geometry and caster angles. Control arms become more important if you're running larger tyres or experience issues with driveline vibration. Consult with our suspension experts if you're unsure whether your setup would benefit from this upgrade.
This kit can be installed by experienced DIY enthusiasts with basic mechanical skills and appropriate tools, with an estimated fitment time of approximately 120 minutes. Drilling is required to mount the airbag brackets to the chassis, so you'll need a quality drill and metal drill bits. The kit includes comprehensive step-by-step instructions with diagrams accessible via QR code. However, if you're not confident with drilling into your vehicle's chassis or routing air lines, we recommend professional installation at a qualified 4WD workshop for optimal results and peace of mind.
Air pressure should be adjusted based on your specific load requirements — there's no single 'correct' pressure. Start with 5-10 PSI for light loads and increase incrementally until the vehicle sits level and sag is eliminated. For typical touring loads with camping gear and roof racks, 20-30 PSI is common. When towing heavy caravans, you may need 40-60 PSI or more depending on towball weight. Always inflate both sides equally to prevent uneven loading, and never exceed the maximum pressure rating specified in your kit instructions. Adjust pressure as loads change for optimal performance.
The Airbag Man helper kit actually enhances off-road performance by maintaining proper suspension geometry and preventing bottoming out on harsh terrain when loaded. You can deflate the airbags for maximum suspension articulation on technical tracks, then reinflate for load support when touring or highway driving. The kit doesn't restrict suspension travel or alter your existing shock absorber performance — it simply adds adjustable support to your coil springs. Many serious off-road tourers rely on air helper kits to handle the weight of recovery gear, long-range fuel, and camping equipment without compromising flex and articulation.
This kit features Firestone airbags backed by a lifetime manufacturer's warranty against defects in materials and workmanship — one of the most comprehensive warranties in the industry. The warranty covers the airbag bladders themselves for the life of the product when used within rated specifications. Additional components like fittings, air lines, and hardware are covered under Airbag Man's standard warranty terms. This extensive warranty coverage reflects the exceptional quality and durability of Firestone airbag technology, giving you complete confidence for years of reliable load-levelling performance across Australia's toughest conditions.
You can safely leave the airbags inflated at your desired pressure for extended periods — there's no need to deflate after every trip. Many Wrangler owners maintain a baseline pressure (around 10-20 PSI) even when unloaded to provide slight assistance and improve ride quality. Inflate further when adding load or towing, then adjust back down if desired. The Firestone airbags are designed for constant inflation and will maintain pressure for weeks without leaking in a properly installed system. However, for maximum suspension articulation during serious off-road driving, you may choose to deflate temporarily, then reinflate afterwards for the drive home.
Perfect Solution for Our Loaded Family Camper
These Airbag Man helper springs have been a game changer for our JK when we head out bush with the kids and all the camping gear. Previously the rear end would sag pretty badly with the roof tent, fridge, and everyone's kit loaded up, but now it sits level and handles so much better on corrugations. Installation was straightforward enough to do at home in the driveway, and the ride quality is noticeably improved even when we're running empty around town.(5)
Best upgrade for my work Wrangler
Chuck these airbag helpers on my JK about three months back and they've been an absolute ripper. Carrying tools and materials every day was killing the rear end, but now it sits level even with a full load. Installation was pretty straightforward for anyone with basic tools, and the ride quality is heaps better than I expected. Worth every cent for a tradie's daily driver.(5)
Perfect Solution for Our Loaded Family Trips
Been using these airbag helpers on our JK Wrangler for six months now and they've completely transformed how the vehicle handles when we're loaded up for camping trips with the kids. The rear end used to sag terribly with all our gear, swags, and water, but now it sits level and the ride quality is actually better than empty. Installation was straightforward enough for a weekend in the shed, and being able to adjust the pressure for different loads is brilliant.(5)
