The Airbag Man Air Helper Kit (RR4593) suits leaf-spring rear Mitsubishi Triton ML-MN models built 2006-2015, adding adjustable air pressure support alongside your existing leaf springs rather than replacing them. Air pressure is manually adjustable from 0 to 100psi through a single external valve, letting you dial in support to suit a canopy, tool boxes or a loaded trailer. Check exact fitment for your build using our Triton parts finder. Stocked in Australia with manufacturer warranty and fitment support from our team.

Because this kit adds adjustable air support rather than a fixed spring rate, you match pressure to your actual load each trip instead of locking in one rate. Start around 20psi for a light trailer and increase toward 100psi for a loaded canopy, tool boxes, water tanks or a heavy caravan tow ball weight. Common rear accessories that change your required setting include steel trays, canopies, long-range fuel tanks, dual batteries and permanently fitted tool boxes.
Fitting is a bolt-on installation most experienced DIY installers complete in a few hours, though we recommend a qualified workshop if you're not confident working under the vehicle. Because the air bags mount to the existing leaf spring perches on ML-MN models, no cutting or drilling is needed. We recommend a wheel alignment check any time ride height changes noticeably under load, and a visual inspection of air lines and fittings after the first 500km. Pair the kit with upgraded control arms if you're also correcting front-end geometry as part of a broader suspension upgrade.
Airbag Man designs and tests its air helper kits in Australia specifically for local utes and load conditions, including the Triton ML-MN leaf-spring rear end. This RR4593 kit is backed by a manufacturer warranty and ships from our Australian stock with fitment support from our in-house team. Tradespeople and tourers running canopies, tool boxes or trailers use Airbag Man kits to add adjustable support without replacing their leaf springs — view the full Airbag Man airbag range for other Triton and 4WD applications.
This kit suits Triton ML-MN owners running a fitted canopy, steel tray, tool boxes or towing a trailer or caravan who notice rear sag under load. It's built for tradespeople carrying gear daily and tourers who load up for weekends away, both needing adjustable support rather than a fixed heavier leaf spring. If you're comparing options across your suspension components, ask our team whether an air helper kit or a heavier-rated leaf spring suits your load pattern better.

Yes, RR4593 fits leaf-spring rear Mitsubishi Triton ML-MN models built 2006 to 2015. It mounts directly to the factory leaf spring perches without drilling into chassis rails. If you're unsure about your exact build or a factory modification, contact our team with your rego or VIN for confirmation. This kit is rear leaf-spring specific and doesn't apply to coil-sprung components elsewhere on the vehicle.
This is a load-support helper kit, not a lift kit, so it doesn't raise unladen ride height. When inflated under load, the air bags help restore ride height and level the rear rather than adding permanent lift. Air pressure is adjustable from 0 to 100psi to match how much support you need for a given load. If you want an actual permanent height increase, ask our team about raised leaf spring options for the ML-MN Triton instead.
RR4593 includes 2 x Airbag Man air bags rated to a maximum 100psi, mounting brackets profiled for the ML-MN leaf pack, U-bolts, a braided air line kit with a single inflation point, a T-piece fitting and a schrader valve. Fitting instructions are included for DIY or workshop installation. The in-cab twin-needle gauge kit and onboard compressor are sold separately if you want dash-mounted control.
Yes, the adjustable 0-100psi air support helps level the rear under tow ball weight and reduces sag when towing a trailer or caravan behind a Triton ML-MN. You increase pressure to suit the actual tow ball load rather than running a fixed heavier spring rate all the time. Many owners run low pressure unladen and increase it only when hooked up to a trailer.
No, control arm upgrades relate to front independent suspension geometry and aren't required for this rear leaf-spring air helper kit. They're only relevant if you're combining this kit with a front lift or correcting front-end alignment as part of a wider suspension upgrade. Our team can advise if your specific build calls for it.
Since this kit doesn't change unladen ride height at rest, a wheel alignment isn't mandatory for the airbag installation itself. If you're fitting other suspension components alongside it, such as a front lift or new control arms, we recommend a post-install alignment check as standard practice. Ask our team if you're unsure what your specific combination requires.
This kit doesn't use a fixed spring rate — air pressure is manually adjustable from 0 to 100psi so you set the support level to suit your actual load each trip. That means one kit covers everything from an empty tray to a fully loaded canopy or towing setup. If you'd prefer a fixed heavier leaf spring instead, our team can talk you through the leaf spring options for ML-MN Tritons.
Because this kit doesn't raise ride height at rest, tyre clearance stays the same as factory. If you're planning larger tyres you'll need an actual lift kit rather than an air helper kit. Speak with our team about combining this kit with a genuine lift if bigger tyres are part of your plan.
RR4593 is covered by an Airbag Man manufacturer warranty against defects in materials and workmanship. It's dispatched from our Australian stock, and our in-house team is available for fitment guidance before and after your purchase. Keep your invoice as proof of purchase for any warranty claim.
Yes, run the air bags at low or minimal pressure for everyday unladen driving to keep ride comfort close to factory. Increase pressure only when you're carrying a load, towing, or running a permanently fitted canopy or tool boxes. This on-demand adjustability is the main reason tradespeople and tourers choose an air helper kit over a fixed heavier leaf spring.
