  SHOCK ABSORBERS VS STRUTS   DISCOVER THE RANGE

The prize jewel of any suspension system is indisputably the shock absorber. But what exactly does a shock absorber or strut do, and with so many options and technologies on the market, how do you know which one is right for you?

Let’s start simple. A shock absorber’s primary role is to control the spring both as it compresses under load and how it rebounds back to position. This damping of energy ensures a smoother ride while helping your tyres maintain contact with the road.

SHOCK ABSORBERS VS STRUTS

Shock absorbers and struts use the same technology to achieve the same goal, but are packaged differently to suit specific vehicle applications.

Basically, a strut is a shock absorber with a flange built into it, so that we can mount a spring directly onto the shock body for an all-in-one compact solution. Modern independent suspension vehicles will most commonly use struts on the front axle and shock absorbers on the rear. However, some wagons use struts on both the front and rear.

TWIN TUBE DESIGN
SOLID, RUGGED AND PROVEN

The true value of a twin-tube shock absorber is the sheer durability of the design. With no foreign tubing or reservoirs and no exposed rods, our line-up of shock absorbers is designed to be uncompromising out in the harshest of Australian conditions.

Twin-tube shock absorbers are by far the most commonly produced shock absorber due to their stability and durability… but it’s not just about the design, it’s what you do with it!

Ironman 4x4 Shock Absorbers vs Struts

IRONMAN 4×4 SHOCK ABSORBERS & STRUTS

Ironman 4×4 offer three shock absorbers/struts, which allows customers to choose a shock absorber that fits both their driving style and their budget.

Most shock absorbers contain the same line-up of components; the main cylinder which contains a valved piston and piston rod, alongside oil and gas. The main difference between shock absorber designs is in how the oil flow is managed and where the gas is stored.

Oil and piston valving is used to manage the speed at which the shock absorber compresses and reopens, while the gas is used to pressurise the oil to prevent it from foaming which in turn destroys its viscosity (thickness) and effective resistance.

When should you get a shock or strut replacement? It’s important to know when you have worn shocks or struts so you can avoid an accident. Some things to look out for include:

  • A bumpy ride, indicative of your shocks and/or struts no longer functioning
  • Longer time to brake and instability during braking
  • The car head dipping forward when braking
  • Lack of control during sharp turns
  • Leakage from shocks

When in doubt, it’s best to leave it to the professionals and get your vehicle checked out at your local mechanic. They will have all the components and tools necessary to fix or replace your shocks or struts.

NitroGas Shock Absorbers by Ironman 4x4

NITRO GAS SHOCK ABSORBER

Nitro Gas shock absorbers use a very proven twin-tube construction. The gas is stored in the outer tube, while the hydraulic oil passes between in the inner and outer tubes.

What’s great about Nitro Gas is that it is a simple and highly-proven design. Nitro Gas is perfect for those who are looking to add a bit of lift to their vehicle, occasionally loading up the car for a camping weekend, enjoying some slow, low-range 4×4, or doing some on-road towing.

Nitro Gas is also the most versatile shock absorber to fit in the widest variety of vehicles due to its slim design.

FOAM CELL SHOCK ABSORBER RANGE

INTRODUCING…

FOAM CELL TECHNOLOGY

Shock absorbers create a huge amount of heat, they are constantly working and converting kinetic energy.

If the oil in a shock absorber gets too hot it can aerate and mix with the nitrogen gas. When this happens it loses its viscosity (thickness) and you experience what is called ‘shock-fade’ where basically your shock absorbers lose their core damping ability.

Foam cell technology uses a sleeve of foam with hundreds of tiny little gas-filled cells which the oil runs over and around. This foam cell prevents the gas and oil from being able to mix ensuring shock-fade is not something you need to worry about.

FOAMCELL SHOCK ABSORBER

Ironman 4×4 Foam Cell shock absorbers take things up a notch.

In addition to unique foam cell technology, Foam Cell shocks are a larger diameter which when combined with the foam cell, allows the oil more contact with a greater surface area of the shock, which in turn provides better cooling.

Foam Cell shocks also have a larger rod and piston which makes them even more robust and allows for greater valving by our suspension specialists.

Foam Cell shock absorbers are great for people who hope to hit a few dirt roads at highway speeds for long periods, tow off-road or tend to have a heavier-than-usual load from time to time. Shock absorbers and struts work harder on heavier vehicles, with more movement generating more heat! A bigger shock absorber with greater cooling capacity is a worthy upgrade.

FOAMCELL PRO SHOCK ABSORBER

The Ironman 4×4 FoamCell Pro range takes our proven foam cell design to the next level.

Utilising the same technology and design, the Pro version is designed with a bigger shaft, bigger piston, and a bigger cylinder.

The increase in size provides not just strength but also greater control in valving and greater cooling efficiency due to the larger surface area.

The Foam Cell Pro offers the greatest level of cooling efficiency and precision valving for the most comfortable ride.

The Foam Cell Pro is a great choice for those who value the best, those who consider themselves true four-wheel-drive enthusiasts, and those who carry heavier loads, especially with increased GVM

VALVING OPTIONS

Comfort valving is a softer valving in the stroke of the piston. It allows the vehicle to more freely ride with the natural movement of the spring. It could be described as a plusher ride, offering a more ‘floating’ feel.

This is most commonly used in the rear of a lighter vehicle to ensure optimal handling in the front and comfort and the rear is maintained.

Performance valving offers the best of both worlds.

Performance valving allows for a great level of both comfort and control. When matched to the rights springs; the optimal blend for a well-balanced vehicle.

Our professional valving is best suited to vehicles that are carrying heavier than standard loads, the heavier valving ensures that the additional weight does not over-run the shock absorber, to ensure control is maintained in the most extreme of conditions.

Firmer shock absorber also provides the least amount of body roll and a more sporty handling experience.
