Do you need to make a Booking?


A car’s suspension maximizes the friction between the tyres and the road surface, to ensure steering stability, good handling and the comfort of the passengers.

A bump in the road causes the wheel to move up and down. The magnitude, of course, depends on the size of the bump. Either way, the car wheel experiences a vertical acceleration as it passes over an imperfection.

What is required of the system is that it will absorb the energy of the undulation, allowing the frame and body of the car to ride undisturbed while the wheels follow the bumps in the road.

 Robert St Automotive Suspension Specialists

Your cars shocks and struts are meant to absorb dips and bumps that your car encounters on the road. Your struts also help hold the wheel in place and are the major factor in stabilising your car when its being driven. The shocks are there to minimise the bouncing involved with the spring inside the strut and provide a smoother ride.

If you are not sure what your vehicles shocks look like? You can see them behind your wheels, Its a long tube with another slightly smaller tube that slides into the larger tube. These tubes are pressured and are filled with fluid to provide the proper pressure for your vehicle.

The struts are basically larger cylinders with large springs inside of them under pressure. Struts help to stabilize your vehicle.

If your shocks or struts get worn out, your car will tend to bump or bounce around more than it should. If not attended this actually can cause a safety concern to your driving. So if you have noticed your car bounce too much after dips and bumps in the road while you are driving, or if you hear odd sounds coming from the wheels. These might be signs that you may need new shocks or struts.
