We supply Old Man Emu suspension - specialised, integrated 4WD suspension systems.
Suspension systems, especially when referring to 4WDs, are extremely complex. Determining the right solution for each 4WD requires special attention to many factors, with weight being the most critical. Old Man Emu 4x4 suspension by ARB approaches this in a unique way.

The Concept
When an emu runs, its powerful legs absorb most of the impact, allowing it to move over all types of terrain while its body remains virtually motionless. This is what Old Man Emu (OME) strives to achieve with its range of fully integrated 4x4 shocks and suspension systems.
The Difference:
Instead of offering a compilation of parts that have been chosen primarily to increase the vehicle's ride height, OME 4x4 suspension provides a range of tuned and matched integrated systems, each offering varying degrees of comfort, load carrying capability and control characteristics.
The Outcome:
Prototype shock absorbers and springs are tested and modified in a variety of terrains and with varying loads to ensure that each shock and spring combination is ideally suited to a vehicle, its varying weights and the conditions it will be used in.


Hi guys (& girls)
Just wanted to say thanks heaps for all the work you have done on my Prado.  I wasn’t sure if I really needed the lift, bar, lights etc. or if I wanted to spend the money but I’m wrapped with the end result!  The lights are unbelievable and driving at night is awesome!  People comment heaps on the bar and how good it looks and I wish I’d taken your advice Morgan and got the lift ages ago!  You know how I use to hate driving my truck – now you can’t get me out of it! It handles so much better and gives me a firmer ride with no body roll and more ground clearance.  I could drive it all week!  Thanks heaps for the solid advice and great service.  It’s always good dealing with you guys!

"I recently purchased a set of Sumo Springs for my 4x4 Landcruiser double cab ute.  I wanted something that would not compromise the ride but when a load was dropped on the ute, would not sink in the rear with the lights pointing skywards.
So far these Sumo Springs seem to be doing exactly what I want.  They don’t noticeably affect the ride yet, when I put on a heavy load – the tray stays level.  
I am very happy with them and have no hesitation in recommending them to anybody in my situation that have to carry heavy loads, but not all the time.  They took about an hour to fit and are doing the job you claimed they would."
Many thanks
