Old Man Emu
Nitrocharger Shocks
Why Buy A Set Of Four
Shock Absorbers? It's a simple fact of life that shock absorbers do wear out and
should be replaced. It's also fact that a vehicle may be equipped with shock
absorbers that were not designed to meet your requirements. Old Man Emu shock
absorbers last much longer than original equipment units. They also reduce pitch
and body-roll. OME shock absorbers will make your vehicle track and handle
better. It will, therefore, be a safer vehicle and the ride will be more
comfortable, regardless of whether your vehicle is brand new or a little older.
But, for the best results, it's strongly recommended that all four shock
absorbers be replaced at the same time. Fifteen years experience in 4WD
suspension, a strict policy of thorough development before introducing any new
product and an extremely successful long-term involvement in off-road racing led
to the production of this, Australia's' best shock absorber. Nitrochargers
unique glacier bush, its Teflon-impregnated piston-rod guide and Teflon-banded
piston eliminate metal to metal contact within the piston tube itself, thus
reducing bore wear, friction and heat. New design multi-stage valves, including
a seven-stage coil sprung compression valve and a four-stage coil sprung rebound
valve, improve the Nitrochargers consistent performance characteristics, enhance
its fine tuning capabilities and increase overall durability. The Benefits Of
Gas Pressurization As the piston travels in a non-pressurized hydraulic twin
tube shock absorber, oil passes through the base or compression valve to and
from the outer tube, which serves as a reservoir. Part of the reservoir must be
filled with compressed air to compensate for movement of the piston rod and its
displacement of the shock oil as the rod enters (compresses) into the shock.
This internal shock air can mix with the oil in the shocks reservoir, and
actually foams with the oil under operation, drastically reducing the
effectiveness of the shock absorbers damping valving and causes fading to occur.
The OME Nitrocharger replaces the air in the shock reservoir of common low
performance shocks with pressurized Nitrogen gas. A major component of the air
we breathe, Nitrogen is a pure, inert gas, without the corrosive and unstable
properties of Oxygen and Water Vapor which are also found in air. Use of pure
Nitrogen gas in the pressurized OME Shock helps provide more consistent damping
and prevents deterioration of the shocks damping oil and internal working
components. Low Pressure Versus High Pressure Essentially, there are two basic
varieties of gas shocks in common usage today: one is the low pressure twin-tube
shock absorber, while the other is the high pressure De Carbon Principle
mono-tube. High gas pressures are the norm in racing car shocks for high speed
applications and short suspension on smooth roads. But the Australian on-road
and off-road environments embody markedly different needs and, in the OME
experience, there are two problems with high pressure shock absorbers. Under low
pressure, the broader range of bottom end softness is able to be easily fine
tuned. Such is not the case with the high-pressure approach, as the system is
inherently stiffer, regardless of the setting. The degree of bottom-end softness
dictates the level of comfort experienced while driving at low speed.
Consequently, the low pressure system is more comfortable and more desirable.
The other problem is that the internal gas cylinder of the De Carbon principle
mono-tube design has a shaft length shorter than the Old Man Emu twin-tube
design. If an OME unit and a mono unit of the same compressed length are fully
extended, the OME unit will extend further. On 4x4 vehicles, therefore. the OME
unit will allow the axle to drop down further and gain traction, dependent upon
suspension design. The walking effect of your 4x4 may be limited by the shorter
traveling mono-tube, but not by the Old Man Emu Nitrocharger.
