Product Code: LA-01 + PX-01 DIGITAL

This is a brand new BOSS air bag load assist kit + DIGITAL In Cab Kit PX01 (Inflation Kit) to suit the rear of ALL Toyota Landcruiser models that come out with leaf rear. This double air bag kit suits vehicles with normal lift up to a 2" lift.


The Load Assist Kit comes with:

  • 2 x BOSS Extreme Series Double Bellow Airbags
  • 4 x brackets (2 upper & 2 lower)
  • Mounting Hardware
  • Quality SAE J844 Government Approved Airline
  • Dual Schrader Valves Mounted in Stainless Panel
  • Instructions for fitting

Boss Extreme series airbags are rated at 2500lb or 1136kg per side and have been government approved tested to over 750psi.

All Boss airbags are manufactured by us and are branded Boss. Beware of unbranded airbags, usually coming from China from other companies.

Average dual cab ute will run around 15-45psi depending on load.

Boss has sold over 13000 load assist kits in Australia, proven over time with 4WD enthusiasts, Mining companies, Tradies, 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 unecessary pressure on any one individual part of your vehicles suspension.


The In Cab kit includes the BOSS PX01 Compressor, digital gauge and controls. As soon as you turn the compressor on, it inflates the 2 air bags. The one-way valves prevent air transferring from one bag to the other so that you have a better ride. A digital gauge is also included.

This kit is used to control Load Assist Kits from inside your cab without the need for a tank and electric valves.

Simple installation and controls bags independently up and down using our PX-01 compressor.


  • 1 x PX-01 12V BOSS Air Compressor.
  • 1 x Stamped stainless steel gauge panel.
  • 2 x Pneumatic Push Buttons for dropping each bag.
  • 1 x 12V momentary switch for compressor.
  • 1 x BOSS 200psi Dual reading digital Gauge.
  • 10 meters of 1/4” J844 DOT Airbrake line.
  • 2 x 1/4” push connect check valves.
  • 3 x Y Connectors.
  • 2 x T Connectors.
  • 4 x 1/4” female push fittings for gauge and buttons.
  • 10 x Cable Ties.
  • Instruction Sheet.


The In Cab Kit includes the BOSS PX01 Compressor, digital dual reading gauge, electric valves, air fittings and switches. When you turn on the compressor, it pumps up both airbags at the same time. It includes a one way valve to prevent air transferring from one bag to the other. This means they are always independent to make for a better ride and cornering. The digital gauge has 2 readings and 2 switches (one for each bag) to open the electric valves to allow the air out and for the bags to deflate. Each bag can be deflated on it's own.

With this upgrade we take out the twin needle gauge and the 2 manual dump valves and replace them with the following:

  • 1 x LED Digitial Gauge - twin read out
  • 1 x Mounting plate
  • 2 x air down electric solenoids with 1/4" T-piece
  • 2 x push button switches to activate the solenoids
  • 2 x sender units with 1/4" T-piece
  • Instructions

This Kit can be run with little or no air for no load or fully inflated for heavy loads. No drilling, welding or cutting is needed. The rubber is a heavier grade than your tyres and individual components are all replacable. All Boss Kits come with a full 5 year warranty, regardless of which vehicle it is in or who fits the Kit.
