Components of a Suspension System

Consumers who pursue the thought of performance modifications and aftermarket modifications of their cars often associate such changes with the instant gratification of having a car with performance parameters equal to that of a sports car. But this boost in power generated by the car’s enhanced engine is unusable if the consumer is unable to retain control of his car. Which is why a vehicle’s suspension system is carefully evaluated right after changes has been made to the car’s main engine, and its significance goes hand in hand with the increased performance of an engine.

A car’s suspension system serves the purpose of delivering friction between the tarmac and the tires, providing stability and confident handling capabilities to ensure ease and comfort for the driver and its passengers. Mechanical engineers often consider two major driving aspects when dealing with a car’s suspension—how it affects the ride (how smooth a car runs over rough terrain) and its handling (how it affects breaking, accelerating, and dealing with corners).

A suspension is composed of three main parts—springs, shock absorbers and anti-sway bars.

Suspension springs come in many different thicknesses and sizes. Different springs tend to alter the riding height of a car, firmness of the ride and the stiffness of the car’s handling. Damaged or faulty suspension springs leads to a decrease in a ride height which reduces the amount of compression for the suspension system to utilize.

Shock absorbers (as the name suggests) helps to dampen and control unwanted spring motion through means of using hydraulic fluid to reduce the vibrations. Other shock absorbers, like one that comes from a Sportsryder performance suspension takes the form of struts mounted inside a coil spring. These struts add structural support to the entire suspension system. While hydraulic fluid-based shock absorbers do the job of controlling the speed that weight is transferred to a car, they do not support the vehicle’s weight, unlike a strut-based shock absorber.

Anti-sway bars complement the shock absorbers to add stability to a moving vehicle. The bar is a rod that stretches along the length of a vehicle’s axle and connects each face of the suspension system. When the suspension system activates from one wheel, the anti-sway bar transfers this movement to the other wheel. This helps to prevent the sway from unbalanced terrain to keep a ride smooth. Cars in this day and age often comes with anti-sway bars installed in their suspension systems. Learn more at
