Suspension, Wheels & Recovery Gear Fitted on the Sunshine Coast
Load Assist & Air Control Options
Boss Air Suspension Sunshine Coast
Boss load-assist airbags provide adjustable rear support for selected utes, American trucks and commercial vans. Add manual inflation for simple operation, an in-cab controller for on-the-fly adjustment, or an onboard-air package where airbag control and tyre inflation are both required.
The Ute Shop can identify a vehicle-specific Boss kit and match it with the appropriate air-control package, with professional fitting available at our Warana workshop on the Sunshine Coast.

Boss Load-Assist Airbag Kits
Boss vehicle-specific load-assist airbag kit with brackets and hardware
Boss load-assist kits mount heavy-duty double-convoluted air springs between the chassis and rear axle. They work with the factory leaf springs to eliminate rear sag when carrying tools, toolboxes, trade gear, service bodies, or towing heavy caravans and work trailers.
- Heavy-duty laser-cut steel brackets engineered for Australian conditions
- Reinforced multi-ply rubber airbags with extreme burst ratings
- Helps maintain proper headlight angle, steering traction, and braking balance
- Protects springs from premature flattening under persistent heavy loads
In-Cab Airbag Controls
Boss heavy-duty dual-bellow air spring component
In-cab control kits allow you to adjust airbag pressures directly from the driver's seat using pneumatic paddle switches or digital electric valves. Dual gauges display left and right bag pressures independently, letting you compensate for uneven drawer, fridge, or water tank weights.
Onboard Air & Tyre Inflation Systems
A Boss 12-volt compressor package paired with a 2-gallon or 3-gallon aluminium or steel air tank turns your ute into a fully self-sufficient mobile air station. Run airbag pressure adjustments, air horns, air lockers, and rapid 4WD tyre re-inflation after a beach or trail session.
Never run airbags completely empty. A minimum operating pressure (typically 5 to 10 psi) must be maintained at all times to prevent the bags from pinching or chafing inside suspension coils or against chassis components.
Professional Installation at The Ute Shop
Proper bracket alignment and torque verification prevent stress fractures and chassis damage. Our Warana technicians ensure all airlines are protected from road debris and heat, with pressure-leak testing completed before delivery.

Frequently asked questions
What makes Boss airbags different from other brands?
Boss utilizes heavy-duty reinforced rubber bellows with thick laser-cut brackets designed specifically for harsh Australian outback and trade conditions.
Can I adjust Boss airbags while driving?
Yes, if equipped with a Boss in-cab control kit or wireless digital controller, you can inflate or deflate the bags from inside the cabin.
Do Boss airbags increase my ute's towing capacity?
No. Airbags level the vehicle and improve braking and handling stability, but do not exceed the vehicle's factory towing capacity or legal GVM limits.
Can I use the onboard air compressor to pump up 4WD tyres?
Yes. When equipped with an onboard compressor and storage air tank, the system easily powers tyre inflation lines and air accessories.
Does The Ute Shop supply and fit Boss Air Suspension?
Yes. We supply and professionally install Boss load-assist kits, onboard compressors, tanks, and in-cab gauges at our Warana workshop.

Workshop Buyer's Guide & Technical Fitment Advice
ADR Compliant
▼
This is the hub for everything that decides how a loaded ute sits, rides and gets itself out of trouble: springs and shock absorbers, load levelling airbags, certified GVM upgrades, winches, recovery gear and the rated points that make a recovery safe. They belong together because they are one system. A lift kit changes how the vehicle carries weight, the weight decides whether it gets stuck, and the recovery gear is what you reach for when it does.
Suspension - what the options actually do
A lift kit raises ride height for clearance and larger tyres, usually 40 to 50mm on a dual cab, which is where most kits stop because beyond that the driveline angles and the ADR height rules start working against you. A load-carrying kit may not lift much at all; it is rated to hold a constant load level rather than to gain clearance, and that is the right kit for a tradesman's ute or a permanent canopy build. Load levelling airbag suspension sits inside or beside the existing springs and is adjusted by pressure, which is the sensible answer for a ute that is empty on Monday and towing a van on Friday - but it manages load, it does not raise your legal limit. That is what a certified GVM upgrade does, and we do those both pre-registration and post-registration. Shock absorbers are the part people under-think: twin-tube units are quiet and comfortable, monotube and remote-reservoir shocks shed heat on long corrugations and are worth it if you genuinely spend time on dirt.
Winches and recovery
Electric winch capacity should be roughly twice the vehicle's loaded weight, which puts most dual cabs at 9,500 to 12,000lb. Synthetic rope is lighter, safer when it fails and easier to handle than steel cable, but it needs a different fairlead and does not like heat or grit. A winch also needs a bull bar with a winch cradle, a battery and charging system that can hold up under load, and rated recovery points bolted to the chassis - the factory tie-down hooks on a ute are not recovery points, and using them is how people get hurt. Snatch straps, soft shackles, recovery tracks, a damper and a set of gloves finish the kit. We stock Runva winches and Carbon Offroad recovery gear, alongside Lovells, Outback Armour, Tough Dog, Dobinsons, EFS 4x4, ORI and Polyair for suspension, and Campboss and Outback Kitters for the touring hardware around it. We are an authorised dealer for all of them and everything we supply is ADR compliant.
Vehicles covered
Ford Ranger and Raptor, Toyota HiLux, Isuzu D-MAX and MU-X, Toyota LandCruiser 79, 200 and 300 Series and Prado, Mitsubishi Triton, Mazda BT-50, Volkswagen Amarok, Nissan Navara and Ford Everest, plus RAM 1500, RAM 2500 and 3500 and the Chevrolet Silverado. American trucks in particular are worth a conversation before ordering - spring rates and kit availability differ a long way from the local dual cabs, and not every kit that fits the truck is certified for it here.
Supplied, fitted and aligned at Warana
Suspension is the category where fitting quality shows up fastest. We fit in our own workshop at 4/43 Premier Circuit, Warana, on the Sunshine Coast, and a suspension job leaves here corner-weighted where the kit calls for it, torqued to spec and wheel-aligned afterwards - an alignment is not optional after a lift, and skipping it is why some lifted utes chew out a set of front tyres in a few thousand kilometres. Customers come through from Kawana, Caloundra, Maroochydore, Mooloolaba, Buderim, Nambour, Noosa, Gympie and Caboolture, and we deliver nationwide for owners doing their own fitting. Tell us what the ute carries, what it tows and where it actually goes, and we will spec it around that rather than around a catalogue.
Common questions
How much lift can I legally run?
As a rule of thumb, up to 50mm of combined suspension and tyre height increase is the straightforward path in Queensland; beyond that you are into certification. There are also driveline and brake-line limits that arrive before the legal one on most dual cabs. We will tell you where your build sits.
Airbags or heavier springs?
Airbags if the load changes - empty during the week, loaded or towing on weekends. Heavier springs if the load is permanent, like a fitted canopy and drawers. Neither one raises your legal GVM; only a certified upgrade does that.
What size winch do I need?
Roughly twice the vehicle's loaded weight, which puts most fitted-out dual cabs at 9,500 to 12,000lb. Undersizing is false economy - a winch working at its limit gets hot and slow exactly when you need it, and it needs a bull bar cradle and a healthy charging system behind it.
Do I need a wheel alignment after a lift?
Yes, every time. Changing ride height changes camber and caster, and a lifted ute that is not realigned will wear the inside edges off a set of front tyres surprisingly quickly. We align in-house as part of the job.
