The Airbag Man Helper Kit uses genuine Firestone air springs mounted above the rear axle to give your Ford Ranger PJ-PK (2007-2011) adjustable load support without replacing the factory leaf springs. Pump the air springs up when towing a trailer or carrying a loaded canopy, then run them soft or empty for a normal unladen ride — the kit doesn't alter your Ranger's factory ride height. It works alongside your existing leaf springs rather than replacing them, cutting rear-end sag and keeping steering and braking predictable under load. Supplied in Australia with Firestone's lifetime warranty on the air springs and fitment guidance from our team.

This is a helper kit, not a fixed spring-rate kit — instead of choosing a physical spring rate, you set air pressure through the inflation valve to suit the load on any given trip. Run higher pressure for sustained heavy loads such as a caravan, slide-on camper or full tool canopy, and lower pressure or empty for solo touring and everyday driving. Common load factors that affect your ideal pressure setting include tow ball weight, tray tool boxes, long-range fuel tanks, and rear-mounted canopies or dual battery setups.
Fitment is straightforward for an experienced DIY installer with basic hand tools, though workshop installation is recommended if you're not confident working around the rear axle and leaf springs. Because the kit doesn't change unladen ride height, wheel alignment isn't mandatory after fitting, but it's worth checking toe and camber if your Ranger is already due for a check. Inspect air line fittings and bracket bolts after the first 500km of loaded driving to confirm everything has settled and stayed tight. If you're regularly carrying heavy constant loads, pairing this kit with load-rated leaf springs or upgraded control arms can further improve geometry and stability.
Airbag Man builds its helper kits around genuine Firestone air springs, a componentry choice used across the load-assist air suspension industry for its rubber bellows and pressure range. Kits are specced for Australian vehicles and load conditions, and the air springs carry a lifetime manufacturer warranty against material defects. Tradespeople and tourers running the Ranger PJ-PK for regular towing or heavy tray loads rely on this kit to keep the rear end level without replacing their factory leaf springs — see the full Airbag Man suspension range for other applications.
This kit suits Ranger PJ-PK owners who tow caravans, box trailers or boats, and tradespeople running loaded canopies, tool storage or generators in the tray. If you want airbag suspension that you can adjust for the load rather than a fixed spring upgrade, this helper kit gives you that flexibility without altering your everyday unladen ride.

Yes, this Airbag Man Helper Kit is built specifically for the Ford Ranger PJ-PK built between 2007 and 2011, covering the 2.5L and 3.0L turbo diesel and 4.0L V6 petrol variants. It mounts to the factory rear leaf springs and axle housing without cutting or drilling in most fitments. If you're unsure of your build date or series, check your compliance plate or use our parts finder for the Ranger PJ-PK before ordering.
This helper kit doesn't lift your Ranger — it's a load-assist system, not a lift kit. Deflated, the air springs sit clear of the leaf spring and your Ranger sits at its normal factory ride height. Inflated, the air springs counteract sag under load rather than raising the unladen vehicle. If you want additional ride height as well, look at our leaf spring range instead or alongside this kit.
The kit includes two Firestone air springs, upper and lower mounting brackets with a U-bolt kit, a braided air line connecting both air springs, a single-point inflation valve, fitting hardware and installation instructions. A compressor or inflation source is not included — most owners use a 12V portable inflator, foot pump, or servo air to top up pressure. Full details are listed in the Kit Includes section above.
Yes, this is one of the main reasons buyers fit this kit. Increasing air pressure in the rear air springs before hooking up a caravan, box trailer or boat reduces rear-end sag from tow ball weight, keeping the Ranger's steering and braking more predictable while towing. Once the trailer is unhooked, deflate the air springs back down for a normal unladen ride.
Not necessarily — this kit doesn't change ride height, so it doesn't affect front control arm geometry the way a lift kit would. Front control arm upgrades are more relevant if you're also fitting front suspension lift components on your Ranger. For this rear leaf spring helper kit alone, no control arm changes are required.
Wheel alignment isn't mandatory after fitting this kit, because it doesn't alter your Ranger's unladen ride height or suspension geometry. It's still worth having your alignment checked if it's due, or if you notice any handling change once the air springs are loaded. This is different to a leaf spring or lift kit installation, which does typically require a post-fit alignment check.
This kit doesn't use fixed spring rates — instead, you adjust air pressure through the inflation valve to suit the load you're carrying on any given trip. Run higher pressure for sustained heavy loads like a caravan or full tool canopy, and lower pressure or empty for everyday unladen driving. If you want a fixed heavier-rate leaf spring instead, browse our leaf spring range.
Because this kit doesn't raise ride height, it doesn't create extra tyre clearance the way a lift kit would. If you're planning larger tyres, you'll need a leaf spring or lift kit upgrade rather than this helper kit alone. This kit is purely about load levelling and towing support on your existing ride height.
The Firestone air springs in this kit are covered by Firestone's lifetime manufacturer warranty against material defects. Brackets and hardware are covered under standard Airbag Man product warranty terms. Our team can talk you through the specific warranty process if you ever need to make a claim.
Yes — run the air springs empty or at low pressure for daily unladen driving and your Ranger keeps its normal factory ride feel. Air pressure only needs to go up when you're towing or carrying a heavy load, then back down for the commute home. This flexibility is the main advantage of a helper kit over a fixed heavy-duty leaf spring.
