Suspension System Components & What They Do

Suspension System Components & What They Do | Fox Run Auto

You're ready for an adventure, but instead of a refreshing family get-away or quick grocery run, you find yourself being jostled around. It's then you truly appreciate the components of your suspension system—working tirelessly to transform your tumultuous trek into a serene sail.

The suspension system is not just about comfort; it's a balance between physics, engineering, and magic (well, almost) that keeps your car stable, ensures tires stay in contact with the road, and protects the vehicle from wear and tear. Let's explore these mechanical marvels that make our rides smooth and secure.

Shock Absorbers

When you hit a bump or dip in the road, they absorb the shock by converting kinetic energy into heat within their hydraulic fluid. This process prevents your car from bouncing excessively and maintains wheel stability. Without them, every ride would feel like navigating through a never-ending earthquake aftershock.


Springs are what give your vehicle its bounce—but in a controlled manner. These metal spirals support the weight of your car and work hand-in-hand with shock absorbers to cushion impacts from road irregularities. They compress to absorb force when you hit a pothole and then rebound to their original shape afterward. There are various types such as coil springs, leaf springs, and torsion bars, each with their own role in keeping your vehicle poised under pressure.


A strut is essentially a shock absorber mounted inside a spring; it's an all-in-one suspension squad member that contributes both to absorbing impacts and supporting the vehicle's structure. They play an integral role in steering stability and alignment, too. If cars were superheroes, struts would be their trusted sidekicks—essential for maintaining a balance between good (comfort) and evil (road turbulence).

Control Arms

Control arms (also known as A-arms) connect wheels to the car frame while allowing them to move up and down smoothly. They coordinate motion control with help from ball joints and bushings—those lesser-known little guys that provide pivot points for movement and reduce friction, respectively.

Anti-Sway Bars

Anti-sway bars stabilize by connecting opposite wheels together through short lever arms linked by a torsion spring. When turning or maneuvering through wind gusts on highways at high speeds, these bars reduce body roll and keep your vehicle level. Thus ensuring better tire contact—and consequently improved handling.
