The Airbag Man Helper Kit is purpose-built for the Ford Ranger PX1 and PX2 (2011-2018), fitting inside the factory rear leaf springs to eliminate sag from canopies, tow bars, and dual-battery setups. It uses genuine Firestone airbags backed by a lifetime manufacturer warranty, with adjustable air pressure to level your load rather than a fixed spring rate. Nylon air lines and full mounting hardware are included so it works alongside your existing leaf spring suspension without replacing it. In stock in Australia now, with fitment support from our suspension team.

This kit is an airbag helper for your existing rear leaf springs, so there's no spring rate to select — instead you adjust air pressure to match your constant load. Heavier setups such as a steel tray, canopy, dual battery tray, long-range fuel tank, or a loaded caravan tow ball weight need higher air pressure to keep the rear level. If you're carrying very heavy constant accessory loads day-to-day, a heavier-rated rear leaf spring from our leaf spring range may suit better alongside this kit.
Fitting the airbags inside the leaf spring pack is a job for an experienced DIY installer with basic hand tools, or your usual suspension fitter, using the supplied mounting brackets and hardware. Wheel alignment is not typically required from this kit alone since it doesn't change unladen ride height, but if you're also fitting a front lift or new control arm upgrades, book an alignment as part of that job. Check air line fittings and bracket bolts for tightness after the first 500km of towing or load-carrying, and re-torque as needed.
Airbag Man builds airbag suspension kits using genuine Firestone air springs, matched to specific Australian 4WD and ute models rather than generic fitments. Every helper kit is backed by a lifetime manufacturer warranty on the airbags themselves. Tradespeople and tourers running the Ford Ranger PX1/PX2 use this kit to keep the rear level under constant load — view the full Airbag Man suspension range for other Ranger applications.
This kit suits Ranger PX1/PX2 owners who regularly carry a heavy canopy, tray, or tools, and tourers towing a caravan or box trailer who need the rear to sit level rather than squatting under load. It's also a practical option for anyone wanting adjustable airbag suspension support without replacing their factory leaf springs outright.
This Airbag Man Helper Kit is in stock in Australia and ready for fast dispatch, with our team on hand to confirm fitment for your specific Ranger build. Browse our full lift kit range if you're also planning a front-end upgrade alongside this rear helper kit.

Yes, this Airbag Man Helper Kit is specifically designed for the Ford Ranger PX1 (2011-2015) and PX2 (2015-2018) rear leaf spring suspension. It uses mounting brackets matched to the factory chassis rail and axle points on these models. If you're unsure which series your Ranger is, our team can confirm fitment using your build plate or rego details before you order.
This is a helper kit, not a lift kit, so it doesn't raise your Ranger's unladen ride height. Instead, the Firestone airbags sit inside the rear leaf springs and are inflated to restore level ride height once you've added weight — canopy, tow bar, or a loaded trailer. Unladen, you deflate the airbags back down and the Ranger sits and rides like standard. If you want an actual lift height, pair this with our leaf spring or front lift options.
The kit includes two Firestone air springs, upper and lower mounting brackets, nylon air lines, an inflation valve, and all mounting hardware needed for installation. Detailed fitting instructions are supplied, and the airbags carry a lifetime manufacturer warranty. It's designed to work with your existing leaf springs, not replace them.
Yes, this is one of the main reasons Ranger owners fit it. When you're towing a caravan or trailer with tow ball weight pressing down on the rear, the airbags can be inflated to counter that sag and keep the Ranger level. This helps maintain consistent handling and headlight aim while towing, then you deflate the bags again for unladen driving.
Not for this specific rear leaf spring helper kit, as it doesn't affect front suspension geometry. Control arm upgrades are more relevant if you're also fitting a front lift kit or raised coil springs on your Ranger. If you're planning both a front lift and this rear helper kit, check our control arm range for correct geometry at ride height.
This kit alone doesn't require a wheel alignment because it doesn't change your Ranger's unladen ride height or front suspension geometry. If you're fitting this alongside a front lift kit or new control arms at the same time, an alignment is required as part of that separate installation. Always check air line and bracket bolt tightness after the first few hundred kilometres of use.
This kit doesn't change your leaf spring rate — it adds adjustable air support on top of your existing springs. You control support level by adding or releasing air pressure through the supplied lines and valve, rather than choosing a fixed spring rate. If you need a genuinely heavier constant load rating, a heavy-duty rear leaf spring from our leaf spring range is worth considering alongside this kit.
This helper kit doesn't raise your Ranger's unladen ride height, so it won't create extra tyre clearance on its own. If you're after clearance for larger tyres, you'll need a genuine front and rear lift kit rather than this airbag helper kit. Our team can recommend a suitable Ranger lift kit to pair with this product if that's your goal.
The Firestone airbags in this kit are covered by a lifetime manufacturer warranty against manufacturing defects. Mounting hardware and air lines are covered under standard supplier terms. Keep your invoice from 4WD Suspension as proof of purchase for any warranty claim, and contact our team if you notice any air loss or fitting issues.
Yes, that's exactly how it's designed to be used. You run the airbags deflated or at low pressure for normal unladen daily driving, then add air pressure only when you're carrying a heavy load or towing. This keeps ride quality close to standard when unladen while giving you load-levelling support when you need it.
