Shock absorbers come in all shapes, sizes and designs – from the outside it’s hard to know what’s what!

Whilst mono-tube shocks are common in aftermarket 4WD suspension, by design they offer less travel for a given external length and can be more prone to failure if impacted by rocks and debris off road; a dent to the single tube can damage the internal components.

Old Man Emu Nitrocharger Sport is a twin tube design with the outer reserve tube providing protection to the internal components off road. Utilising the latest advances in shock absorber technology, Nitrocharger Sport is the most finely tuned 4×4 shock absorber on the market.

Old Man Emu’s Ride Control Engineers spent countless hours in design and testing to ensure Nitrocharger Sport valving is precisely matched to an OME spring selection that is right for the accessories fitted to your vehicle, as well as your load requirements.

Testing is carried out both in the field with sophisticated data logging equipment, as well as inside the OME laboratory using shock dynamometers to ensure durability under all conditions. With Nitrocharger Sport’s vehicle specific valving technology, owners will experience improvements in both ride control and comfort whether it be on or off road.

WHAT IS COMPRESSION AND REBOUND DAMPING?

Damping refers to the slowing of the shock absorber’s oscillation. This is controlled by a series of valves that slow the movement of the hydraulic fluid through the piston. Valving controls the movement of the pistons both during compression and rebound strokes.

WHAT EFFECT WILL THESE ADJUSTMENTS HAVE ON A VEHICLE?

Adjusting the compression valving has an effect on how comfortable or firm the suspension is when the suspension of the vehicle compresses. Too firm and the vehicle will feel every bump and ripple in the road surface as the shock tries to prevent the spring from freely compressing. Too soft and the ride will become more comfortable, however, more body roll can be felt when tackling corners and the vehicle may nose dive during braking, resulting in less control. The suspension may also easily bottom out on the bump stops.

Adjusting rebound valving effects the rate at which the shock allows the spring to return back to ride height once it has been compressed. Higher rate springs are used to maintain correct ride height when either accessories or greater constant loads are added to the vehicle. When these springs are compressed with greater load, the energy stored within the spring is also greater and requires extra damping control as it rebounds. Not enough rebound control may cause the shock absorber to top out, causing internal damage to the shock or allow the suspension to bounce numerous times after hitting an obstacle, resulting in less control of the vehicle.
