Why Old Man Emu?

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 4×4 suspension by ARB approaches this in a unique way.

Instead of offering a compilation of parts that have been chosen primarily to increase the vehicle’s ride height, OME 4×4 suspension provides a range of tuned, matched and integrated systems, each offering optimum levels of comfort, load carrying capability and control characteristics.

The complete Old Man Emu suspension range incorporates more than just 4×4 shock absorbers and springs. At ARB, we take integration to the highest level with our own selection of bushes, U bolts, centre bolts, spring liners, trim packers and suspension fitting kits.

Development and Safety

Old Man Emu employs a team of full time ride control engineers to carry out an exhaustive testing and development program on each component in an Old Man Emu suspension system. Access to a long list of sophisticated test equipment ensures all development work has an unrelenting, no compromise approach.

During development, each new Old Man Emu suspension system is tested not only for practical performance, but also to ensure compatibility with modern vehicle safety features such as electronic stability control, an area in which ARB has invested heavily in.

 

Nitrocharger Sport Shock Absorbers

Where the purpose of a spring is to carry the load of a vehicle and its cargo, a shock absorber works to control the spring by absorbing excess energy and, in doing so, has a profound impact on your vehicle’s ride and handling.

During the development of OME’s Nitrocharger Sport shock absorbers, particular focus is placed on how well they are matched to the specific springs they’ll be controlling, with Ride Control Engineers tailoring shock absorber valving to work with the different springs in the range, often resulting in multiple shock absorber options for each vehicle.

Whether it’s for work or play, ARB has a solution for just about any application.

Nitrocharger Sport Advantage

The Nitrocharger Sport range utilises significant advances in key componentry and the latest in valving technology to provide tremendous improvements in ride, comfort and handling over all terrains.

Vehicle specific valving ensures the proper valving is matched to your spring selection, accessory fitment and load carrying requirements, meaning there’s a Nitrocharger Sport Shock Absorber to suit your needs, no matter what the terrain or intended vehicle use.

Nitrocharger Sport Shock Absorbers offer the most cohesive, balanced and finely tuned valving system on the market.

Old Man Emu Springs

When undertaking remote area travel, the need to carry sufficient fuel, water, vehicle spares and safety equipment invariably means that your 4WD will be fully loaded, placing a lot of strain on suspension components.Combine this with punishing off road conditions, and the limitations of standard springs soon become apparent. Whether it’s coils, leaves or torsion bars, Old Man Emu springs are designedto improve the load carrying capability of your 4WD, allowing you to tackle more challenging terrain with confidence.

Leaf Springs

Old Man Emu leaf springs are engineered to provide optimum ride performance irrespective of the operating conditions in which they operate.

Numerous spring options are available to suit a multitude of applications, allowing you to set your vehicle up for recreational or commercial purposes.

Feature packed, a set of Old Man Emu leaf springs, matched to a set of Old Man Emu 4×4 shock absorbers will deliver vastly improved ride, handling

and load carrying capability.

Leaf Springs

Leaf Spring Features

  • Draw tapered and diamond cut leaves ensure the load is progressively distributed over a larger surface area, reducing the high stresses that develop at leaf ends, increasing ride comfort and longevity

  • Leaf clamps are bolted to allow installation of anti squeak nylon liners

  • Fully scragged to ensure the spring takes a permanent ‘set’ which reduces the risk of sagging

  • Load testing ensures the spring meets the required specification

  • Military wrap designed to provide added safety

  • Re-greasable nylon interleaf anti friction pads reduce friction at the leaf tips where the load is the greatest

  • Flat axle seat area allows a positive, safe axle mount reducing spring stress and increasing spring life

  • The tension side of all leaves is shot peened to reduce spring stress. This process can double the life of a spring

  • Two-stage leaf pack featured on most rear springs for optimum comfort. When unladen, the vehicle is largely riding on the primary stage, with the secondary stage providing additional support when a heavy load is added

PLEASE NOTE: Most Old Man Emu Leaf Springs have all the listed features, but where design or a physical limitation exists, one or more of these features may not be incorporated. Please check with your OME licensed dealer for further information.

Greasable Shackles

Should your Old Man Emu 4WD suspension system include leaf springs, bushes require periodic lubrication to ensure longevity.

OME greasable shackles and pins facilitate this without the need to remove the shackles, greatly reducing the time and effort involved.

  • Unique, easy bolt together assembly eliminates out of angle shackle pin to side plate’ problems commonly associated with press fit assemblies

  • Each pin has two grease outlet holes to guarantee maximum grease coverage between the shackle pin and the spring bush – increasing bush life and improving ride quality

  • Heat treated pins ensure long life under heavy loads and off road conditions

  • Side plates are zinc plated for protection against corrosion

Coil Springs

ARB designs an extensive range of Old Man Emu coil springs for each vehicle, using state of the art micro-alloyed spring steel to ensure superior resistance to sagging and corrosion. With such a wide range on offer, coil springs can be better matched to your specific load requirements and intended vehicle usage. While ride height increases are attained, a greater emphasis is placed on ridecontrol improvements. Further fine tuning is achieved when the springs are matched to a corresponding set of Old Man Emu shock absorbers, delivering a fully integrated system designed specifically to suit your vehicle.
