The fundamentals behind how coil-overs work

Improving the suspension of a car is essential for ensuring good handling, which in turn is crucial for safe driving. Improving vehicle handling ensures the driver not only greater security, but confidence as well. coil-overs are the optimal solution for anyone looking to upgrade the suspension system of their vehicle. The term coil-over broadly refers to coiled springs that go over a shock. Basically they are part of the car’s suspension system being designed to absorb the shock loads sent to the wheels. For this reason, they are the most important component of the car. While it is clear that coil-overs Australia are a big investment, not many people actually understand what they are buying.

Explaining how the automobile suspension works

Coil-over is actually short for “coil spring over shock” and it comprises a shock absorber and a coil spring that is wrapped around the shock body of the vehicle. The coil-over system acts as a suspension; it controls the rocking motion caused by the wind at speed. This is very useful when experiencing changes in road surfaces because these differences push the car up and down. The main role of the shock absorber is to give tighter handling with less swaying. In the absence of a shock absorber, the spring would oscillate up and down until the initial force would be damped by the spring. From a performance standpoint, automobile suspension keeps the tyres on the ground.

At the heart of the coil-over

The shock is basically at the heart of the automobile suspension device. Similar to any other shock, the mount of the coil-over connects to the chassis, while the lower mount connects to the lower A-arm. The shock controls unwanted oscillations and reduces the vibrations caused by the wheels and chassis. For example, when the driver hits a bump, the energy is absorbed and transmitted to the shocks. Since the shocks dampen the vibrations, they are unnoticeable. In addition to reducing vibrations and controlling spring movements, they eliminate rocking, dipping, wheel spinning and other things that are not supposed to happen when someone is turning or stepping on the brake.

Not all automobile suspension devices are created equal

There are more than one shock absorber that exists. There are three types of automobile suspension devices: OEM spring-over shock assemblies, split-fit coil-overs and full-bodied coil-overs. The first automobile suspension type consists of a conventional shock that is surrounded by a coil spring. It is typically non-adjustable and features a fixed-length body. The second one is more complex  as it consists of an aluminium tube that slides over and sits on the existing shock’s perch in order to alter the ride height.  The third one is the full-body automobile suspension type that replaces the entire factory and spring assembly. Not only does it feature threaded lower bodies that shorten the shock without altering the spring compression, but it also allows a lower ride height. Full-bodied suspensions systems are the most complete kit because they come with everything.
