Universal Rear-End Kit | Boss Air Suspension

£635.00 inc. VAT

This kit is a universal (multi-fit) load-support kit from Boss Air Suspension.

As a universal kit, it can fit almost any vehicle, although some drilling of the brackets to secure may be required (although not necessarily!) It is also possible that on some vehicles a mounting tag may have to be welded on. This kit is ideal if you can’t find a bolt-on kit for your van or pick-up. In this case it will usually get you between 70% and 90% of the way there.

Just like any other load-support kit, it is fitted in addition to your vehicle’s rear spring to offer support, stability and extra comfort to your ride.

It can be inflated simply through Schrader (tyre) valves, or through an air management system of your choice (see ‘Options’ tab below for more info).

All Boss airbags are manufactured by Boss Air Suspension and are branded Boss.

Boss has sold over 13,000 load-support in Australia, proven over time with 4WD enthusiasts, mining companies, traders, 4WD tour operators as well as in agricultural vehicles, trailers and motorhomes, limited only to your imagination.

To get the best performance from your kit, inflate airbags just enough to achieve a level ride height. By doing this you are also allowing all of the suspension components to share the extra load of the vehicle and not putting any unnecessary pressure on any individual part of your vehicle’s suspension.



AirRide Sales Limited offer a warranty on Boss Air Suspension kits for a period of 5 years from time of purchase. This warranty is limited to the original purchaser and subject to registration at the time of fitting. If you fail to register then a 1 year warranty is offered.

If the kit does not appear to fit – STOP and call us, as a vehicle misidentification may have occurred. Kits will be accepted for return and exchange only if they are undamaged. The buyer must cover the return postage.


Car kits can be supplied with or without air management, although going without isn’t advisable if you have air on all four corners of your vehicle.

Air management allows you to get the very best from your kit at all times. It allows the ride height to be adjusted for road, weather and load conditions, while also giving you a street-skimming stance when the time is right.

We have four main management options for cars at AirRide. Read on to find out more:

No compressor, no tank

You can have a car kit with no air management system, but this is not recommended. With this option you will receive the air bags, brackets and struts required for a basic air suspension system, but no compressor or tank, as without some form of control system the compressor and tank would not be able to function correctly.

Manual Paddle Control (MPC)

MPC is controlled by four buttons, one for each air bag. These buttons act like electric-window switches, meaning you can either raise or lower the amount of pressure in each air bag by pressing up and down on each switch. The switches will normally fit somewhere on your dashboard.

MPC comes with an aluminium, 100% duty cycle compressor with up to 200 PSI and an air tank, so you can adjust your ride height whenever you wish (as long as it’s safe). It also comes with twin gauges and a tank gauge.

Solenoid control kit

Solenoid kits are controlled in the same way as an MPC kit, with four electric window-style buttons. However, solenoids act much faster than manual controls.

You can get either standard or advanced solenoids from AirRide. Advanced solenoids run much faster than the standard ones and can be installed a lot easier, as the come in blocks of two, rather than one.

Our solenoid kit comes with a 100% duty cycle compressor and tank for instant adjustment, as well as twin gauges and a tank gauge.

Digital computer system

The Air Lift 3P computer system electronically controls the amount of pressure in each air bag. This can be controlled either with a wired controller or a phone app. You can also set up to five pre-set heights, meaning you can slam or raise your car with just a single touch. The computer will also automatically alter your height to allow for road conditions. This is also the easiest system to install, meaning you’ll save money on installation, as compared to the MPC kit or solenoid kits.

The computer system also comes with an aluminium 100% duty cycle compressor with up to 200 PSI and an air tank, allowing for constant adjustment.

Other options

If you would prefer an air management system other to those listed, please feel free to call or e-mail us. We are happy to discuss your personal requirements and make sure you get the management system that is right for you.
