7 Common Parts in the Car Suspension Systems and the Functions

The suspension system is basically the main stabilizer of the vehicle. When you’re driving over rough terrain or road conditions, the suspension system absorbs all the vibrations and impact that comes from driving through these areas. This allows for the driving experience to be more comfortable for the people in the cabin, so they’re not getting bounced around and jerked all over the place. It also helps sustain the health of the car as well.

The car suspension system is comprised of hundreds of components. They all support the weight of the vehicle as it travels along on the road. Not only does it absorb the impact of things like potholes and bumps, but it also allows you to turn the steering wheel so that your vehicle turns are much smoother.

Suspension System Components

Rather than explain each individual part, we will go over the most important parts of the suspension system. Below is a list of these parts.

1. Coil Springs

When you drive over a pothole or bump, the coil springs are responsible for absorbing this impact. Sometimes there will be metal rods which do this rather than coil springs, but most vehicles use the coil springs for this purpose. Since springs can bend, it makes it easier for them to absorb the impact of the vehicle. As a result, the vehicle does not get damaged, and the people inside the vehicle remain fine.

2. Tires & Wheels

Everyone is familiar with tires and wheels. They sit below the vehicle on the outside where everyone can see. The tires touch the ground as they rotate on it. Whatever you’re driving over, the tires receive the impact first. You must have good treads for your vehicle to remain stable. Otherwise, the stability will be off if your tires are worn.

3. Shocks

The shocks are the shock absorbers of the vehicle. Together with the coil springs, the impact of driving over potholes and bumps is reduced because of the shocks. It is actually the shock absorbers which stabilize the springs after they experience this impact.

4. Linkages & Rods

The rods serve as metal links between various parts of the suspension. Because they’re metallic, they are quite durable and should stay strong for as long as you own the vehicle. Unless you get into an accident, you should never need to replace the rods.

5. Bushings & Bearings

The bushings and bearings are what secure the rods to the various components that are linked together by them. The components can perform twisting and sliding movements because of the bushings and bearings.

6. Frame

The entire skeleton of the suspension is the frame. It carries the weight of the whole vehicle and its components around. Additional components assist it with carrying the engine and body too. But most of the vehicle’s weight falls upon the frame. That is why certain vehicles can only handle a certain amount of load. If you start packing more items into your vehicle, the frame and suspension might not be strong enough to support all that added weight.

7. Steering System

The steering system is separate from the suspension system, but the two systems collaborate in order for the wheels to turn smoothly. The steering system even controls several of the suspension system’s components, such as the wheels, joints, tie rods, and linkages.


If you want a smooth driving experience while keeping your vehicle’s components and engine safe, then pay attention to the health status of your suspension system. If there are ever bad components in it which need replacing, then you must replace them to protect your vehicle.
