Best Digital Airbag Inflation Kit for Towing 2026
Towing with load assist airbags means constantly adjusting air pressure between an empty run and a loaded one. A digital airbag inflation kit takes that guesswork out of the cab, letting you dial in the right PSI from the driver's seat instead of crawling under the tray with a hand pump.
- Boss Digital Airbag Inflation Kit PX01 3-Button suits most towing setups and adjusts pressure from the cab - Buy.
- Skip analogue-only controllers if your load changes week to week; digital kits let you dial in exact PSI on the move.
- The complete PX01 compressor kit adds a bare compressor for utes with no existing onboard air - Buy.
- Impressor Digital In-Cab 3-Button suits drivers who want a cleaner, factory-style dash display - Consider.
Why this matters
Load assist airbags only work properly when the pressure matches the load. Too soft and they do nothing under a loaded trailer. Too firm and the ride turns harsh on the return trip empty.
A manual system means pulling over, connecting a hand pump or 12V inflator to a valve, and checking a gauge by eye. A digital airbag inflation kit puts that same adjustment on a dash-mounted controller, so you can top up or bleed pressure while the vehicle is moving or stationary.
Boss Air Suspension has sold over 50,000 load assist kits across Australia, and the digital controller range exists because customers kept asking for an easier way to manage pressure changes on the road. If you want more background on how these controllers work, the digital air controller buying guide covers the fitting and calibration basics in more detail.
This guide ranks the current Boss digital airbag inflation kit options for towing setups in 2026, based on what each kit includes, who it suits and where it fits against the rest of the range.
How we ranked these kits
Each kit is assessed against four practical measures: what's included in the box, whether a compressor and tank are part of the package, how the controller is operated, and how well it suits a vehicle that alternates between towing and unloaded driving.
Kits that arrive as a complete package with compressor, tank and fittings rank ahead of bare controllers for anyone starting from scratch. Kits built around a 3-button digital interface rank ahead of single-button or analogue setups for day-to-day pressure adjustment while towing.
None of these rankings imply a change to legal payload, GVM or towing capacity. Load assist airbags support the existing rear suspension - they don't add capacity beyond what your vehicle's compliance plate allows.
The ranked list
1. Boss Digital Airbag Inflation Kit PX01 3-Button - the straightforward digital upgrade
This is the entry point into digital pressure control for a vehicle that already has a load assist kit fitted. The 3-button controller lets you inflate, deflate and read pressure without leaving the driver's seat.
It works well for tradies and tow vehicle owners who adjust pressure regularly between loaded and unloaded runs. Buy if you already run Boss load assist airbags and want cab control without buying a full compressor package.

2. Boss Digital Airbag Inflation Kit with PX01 Compressor - the complete setup
This kit bundles the digital 3-button controller with a PX01 12V compressor, giving you everything needed to run digital pressure control without sourcing a separate air source.
It suits caravan and camper trailer tow vehicles that don't already have onboard air fitted. Buy if you're starting from zero and want one purchase that covers the controller and the compressor.

3. Impressor Digital In-Cab 3-Button - the premium display option
The Impressor digital in-cab kit uses the same 3-button logic but with a different display housing, aimed at drivers who want a neater dash finish that blends with factory switchgear.
Function is close to the standard PX01 digital kit, so the decision usually comes down to how it looks on your dash rather than what it does. Consider if fit and finish matter as much as function.

4. Digital In-Cab Upgrade Stage 1 3-Button - the upgrade path
This option is built for owners who already have an analogue or basic onboard air setup and want to upgrade to digital control without replacing the compressor or tank.
It's a sensible middle step if your existing hardware still works fine and you only need the control side upgraded. Consider if you're upgrading an existing system rather than building one from scratch.
5. Boss Auto Pressure Controller Kit with PX06 Compressor, 9L Tank, Fittings, Water Trap and Nitto Coupling - the heavy-duty package
This is the largest package in the range, built around a PX06 compressor and a 9-litre aluminium tank rather than a small in-line unit. It's aimed at setups that need reserve air for tyre inflation or air lockers as well as load assist.
If your onboard air needs go beyond just the airbags, this is the kit that covers more ground. Consider if you want one system doing double duty for suspension and tyre inflation.
6. Boss Auto Pressure Controller with PX03 Compressor and Fitting Kit - the mid-tier option
Slotting between the entry-level 3-button kits and the 9L tank package, this controller pairs with a PX03 compressor and includes the fittings needed for a standalone install.
It's a fair choice for vehicles with moderate towing frequency that don't need a large air reserve. Hold unless the smaller PX01-based kits don't suit your compressor preference.
7. Boss Auto Pressure Controller with Fittings and Water Trap to suit ARB Compressors - the compatibility option
This kit skips the compressor entirely and is built to pair with an existing ARB compressor already fitted to the vehicle, adding the controller, fittings and water trap around it.
It only makes sense if you've already invested in a compatible compressor. Consider only if that applies to your setup.
8. Impressor In-Cab Analogue Kit - the one to skip for this use case
This analogue controller still does the job of inflating and deflating airbags, but without digital pressure readout or button-based control. For a vehicle towing regularly with changing loads, that means more guesswork at the gauge.
Skip this one specifically if you're after digital control - it's a fine budget option, just not what this guide is ranking for.
“If you're swapping between towing and unloaded driving every week, a digital controller earns its keep on convenience alone.”

Where to buy
Buy a digital airbag inflation kit as a complete package if you don't already have a compressor fitted - mixing components from different brands can create fitting and pressure-rating mismatches.
Check that the kit you're buying matches your existing load assist airbags before ordering the controller separately. Boss Air Suspension kits are designed to work as a matched system, and mismatched pressure ratings can affect performance.
Confirm warranty coverage before you buy. Boss digital controllers and load assist kits carry a five-year warranty when purchased and fitted correctly, which is worth checking against any third-party or generic controller you're considering.
FAQ
What does a digital airbag inflation kit do?
A digital airbag inflation kit lets you inflate or deflate your load assist airbags from a dash-mounted controller instead of a manual valve. It shows live pressure on a digital display so you can match PSI to your current load without guesswork.
Is a digital controller better than an analogue one for towing?
For vehicles that switch between towing and unloaded driving often, yes - a digital controller gives you a precise pressure readout and cab-based adjustment. An analogue setup still works but relies on a separate gauge and manual valve.
Do I need a compressor to run a digital airbag inflation kit?
Yes, unless you already have one fitted. Kits like the Boss Digital Airbag Inflation Kit with PX01 Compressor include the compressor, while controller-only kits assume you already have onboard air.
Will a digital controller increase my towing capacity?
No. A digital airbag inflation kit adjusts pressure in your existing load assist airbags to improve stability and reduce rear-end sag - it does not change your vehicle's legal payload, GVM or towing capacity.
How much does a digital airbag inflation kit cost in 2026?
Pricing varies by kit and whether a compressor is included, since bundled compressor kits cost more than controller-only options. Check current pricing on the Boss Air Suspension site for the specific kit you need.
Can I upgrade my existing analogue kit to digital?
In many cases yes. Options like the Digital In-Cab Upgrade Stage 1 3-Button are built to add digital control to a vehicle that already has a compressor and tank fitted.
Do digital kits work with any load assist airbags?
Digital controllers are designed to work with the load assist airbags they're paired with. Confirm your existing airbag kit's pressure rating matches the controller before combining components from different sources.
One last thing
Most drivers underestimate how often they'd actually adjust pressure if it only took three button presses instead of a roadside stop with a hand pump. That's the real gap a digital airbag inflation kit closes - not a performance upgrade, just fewer excuses to leave the pressure wrong for the load you're carrying in 2026.
