4WD Suspension Systems Perth: What You Need to Know

Four-wheel drive (4WD) vehicles can handle some pretty rough terrain, but they can’t do it alone. Several components work together to ensure you can navigate the most challenging trails.

This article will explain what 4WD suspension systems are, why they are important and what they do. It also details the different types of 4WD suspension systems used in modern vehicles and explains how each works.

What is a 4WD Suspension System?

If you have ever seen or driven a 4WD vehicle, you have experienced the benefits of a 4WD suspension system. These systems allow the wheels and axles of the vehicle to move independently from each other, but they remain connected by an axle or an articulated joint. The main components that make up a 4WD suspension in Perth system are:

Front axle assembly: The front axle is the frame that connects your vehicle’s wheels to your other wheel and tire assemblies. This is where your wheel bearings and axle shafts are housed.

Front suspension system: The front suspension system is designed to distribute steering forces from bump steer to wheel wrap-up. It also helps to stabilise your vehicle as it travels over rough terrain.

Rear axle assembly: The rear axle is the frame that connects your vehicle’s wheels to your other wheel and tire assemblies. It is typically designed to connect the back of your vehicle with the more stable front-end components of your 4WD system.

Rear suspension system: This system may include a shock absorber, which dampens springs and limits movement. It also helps take up excess travel during heavy loads or while negotiating rough trails. It can be “leaf spring” or “torsion bar,” depending on what type of vehicle you own.

What is a 4WD Suspension System Used For?

4WD vehicles are designed for adventurers who travel off-road or on rugged terrain. The 4WD suspension systems allow a driver to switch from two-wheel drive to four-wheel drive, depending on the conditions and terrain of where they are driving. Although most modern trucks and 4x4s have automatic systems that switch between 2WD and 4WD, some still require you to push a button or turn a knob on the dash. This lets you control when your vehicle switches from 2WD to 4WD, which is essential for serious off-roaders who need better traction in loose soil or mud.

How do 4WD Suspension Systems Work?

A 4WD suspension in Perth ensures that the wheels and tires of your vehicle are properly aligned, which is necessary for optimum performance. The front axle assembly and suspension system also help to minimise body roll and maintain steady air pressure under the tires as they move over rough or rutted terrain. The rear axle assembly and rear suspension system help to stabilise the entire vehicle, giving it extra traction over a difficult surface when you turn corners in off-road conditions.


Most modern vehicles have a 4WD suspension system that helps the car or truck handle the rugged terrain if you’re driving on an all-terrain vehicle. These systems can be pricey to install, so be sure to shop around for a good deal if you need a helper for your 4WD vehicle. It also helps to access basic maintenance tools, as every time you get in and out of your vehicle, you put wear and tear on these parts.
