Nitrocharger Sport Shock Absorbers

During the development of Old Man Emu’s Nitrocharger Sport shock absorbers, Ride Control Engineers tailor shock absorber valving to work with the different springs in the range, often resulting in multiple shock absorber options for each vehicle.

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 offers a complimentary Front Axle Load Capacity Upgrade for a series of popular 4WDs with every full suspension installation?

Vehicle Specific Bushes

High quality, vehicle specific bushes manufactured from polyurethane and rubber materials for extended life.

Vehicle Specific Bushes

High quality, vehicle specific bushes manufactured from polyurethane and rubber materials for extended life.

Dirt Shield

Impact resistant, polyamide dirt shield provides additional protection from stone chips and off road debris.

Piston Rod

Super strong 18mm induction hardened chrome piston rod is engineered to handle rigours of heavy loads and tough 4x4 touring.

Triple Lip Oil Seal

Large, durable seal incorporates a gas retention check valve design to virtually eliminate contaminant damage while providing outstanding gas and oil retention.

Rod Guide

Large, low friction Teflon impregnated bronze bushing for long lasting durability.

Slip Ring

Teflon infused bronze slip ring ensures a more consistent and uniform damping performance by providing better control of oil flow between the rod and rod guide.

Nitrogen Gas

Increases the temperature operating range and improves oil flow through the valving, ensuring optimum performance.

High Flow Piston

Free flowing design reduces aeration and high oil temperature, extending shock absorber performance under harsh conditions.

Dual-Stack Deflective Disc Technology

Durable rebound and compression multi deflective disc stacking on either side of the free flowing piston allows infinite tuning options.

High Quality Oil

Petroleum based, high performance formula designed to resist fade and aeration for improved durability and shock absorber performance.

Heavy Gauge Reserve Tube

Heavy gauge (1.6mm) steel reserve tube is 23% more effective than common 1.3mm wall tubing to protect internal components from stone damage.

Multi-Disc Compression Valving

Six valving discs allow greater valving options for maximum ride and handling performance.

  • Mono tube vs twin tube shocks

    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.

  • Extra comfort - both on and off road

    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.

  • Compression and Rebound damping

    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.
