Truck Suspension 101

Even if you don’t know a lot about commercial trucks, you know that the suspension system is a critical component. Just like the transmission or the brake system, your suspension is an integral piece that keeps your truck running properly so you can get the job done. Here’s a closer look at how the truck suspension system works.

There are three main parts to your truck’s suspension: the springs, the dampers, and the anti-sway bar. All of these pieces work together to maximize stability while driving, provide good handling for the driver, and ensure that everyone inside the vehicle is comfortable.

The springs are responsible for absorbing the regular impacts that your truck will encounter, such as a bumps or ruts on the road. In heavy duty commercial trucks, lead springs are used, while passenger cars generally have coil springs.

Dampening components also play an important role. These parts control how far the spring extends and also release the energy that is absorbed from the impact. Snubbers, or shock absorbers, work to regulate the motion of the springs and lessen vibratory motions the vehicle experiences. Struts are another type of shock absorber that are found within the spring. In addition to aiding in shock absorption, they also provide structural support for the truck.

The final piece of the suspension system is the anti-sway bar, also known as the anti-roll bar. This piece consists of a metal rod that spans the axles and connects the suspension pieces together. Responsible for transferring movement during turns, the anti-sway bar curbs swaying and helps maintain a smoother and more level ride.

As you can see, your truck’s suspension system plays a large role in the smooth operation of your vehicle. If you notice reduced stability or swaying, it may mean there’s a problem with the suspension. Don’t wait to have this issue addressed, and letting it continue can lead to even greater problems.
