Suspension Struts: How They Work and Why They Matter

Off-road driving can put a lot of stress on a vehicle’s suspension system. From bumpy terrain to sudden drops, the shocks and impacts can take a toll on even the most durable vehicles.

Suspension struts are an essential component of a vehicle’s suspension system, providing support and stability to the vehicle while driving on challenging terrain. If you’re a hardcore off-roader, it pays to know what suspension struts are, how they work and why they matter for your vehicle.

So, what are suspension struts?

Part of a vehicle’s suspension system, suspension struts are designed to absorb the shocks and impacts of driving on uneven surfaces to provide a smooth and stable ride. These essential components are typically located near the wheels of the vehicle and are connected to the chassis and other suspension components.

How do suspension struts work?

Suspension struts work by dampening the shocks and vibrations caused by driving on rough terrain. When a vehicle drives over a bump or a pothole, the suspension struts compress, absorbing the impact and reducing the amount of energy transferred to the vehicle’s body and occupants. When the vehicle returns to its normal position, the suspension struts extend, providing the necessary rebound and stability to the vehicle.

Types of suspension struts

There are two main types of suspension struts: hydraulic and gas-filled. Hydraulic struts use oil to absorb and dissipate the shocks and vibrations. They are commonly used in older vehicles and can be prone to leaks and wear over time.

Gas-filled struts, on the other hand, use a pressurised gas, typically nitrogen, to absorb the shocks and vibrations. Commonly used in modern vehicles, they are more durable and efficient than hydraulic struts.

Why suspension struts matter for off-road enthusiasts

Without the proper support and stability provided by suspension struts, shocks and impacts can cause damage to your vehicle’s body, suspension components and occupants. High-quality suspension struts can improve a vehicle’s handling, making it easier to navigate through challenging terrain and enhancing the overall off-roading experience.

When to replace suspension struts

Like any other component of a vehicle, suspension struts can wear out over time and lose their effectiveness. Signs that it may be time to replace your suspension struts include:

  • Reduced ride quality
  • Increased bouncing or swaying while driving
  • Uneven tyre wear
  • Vehicle leans to one side

If you notice any of these signs, have your suspension system inspected by a professional mechanic. Should they recommend a replacement, know that replacing worn-out suspension struts can improve your vehicle’s performance and safety and your overall driving experience. 

To make sure you’re getting suspension struts of the highest quality, turn to reputable manufacturers like Ironman 4×4.


Understanding how suspension struts work and when to replace them can improve your off-road experience and keep your vehicle in top condition. As an off-road enthusiast, investing in high-quality suspension struts can make a significant difference in the safety and performance of your vehicle, allowing you to tackle any terrain with confidence.
