What are Sway Bars and Why are They Important?

As a critical component of a vehicle’s suspension system, sway bars regulate the position of the car to enhance stability. They’re often referred to as anti-roll bars or stabilisers, as their primary function is to offer better balance. Sway bars are particularly beneficial for larger and taller vehicles that have a higher centre of gravity.

For many cars, they’re highly useful and a simple component that can protect passenger safety and vehicles from expensive damage, as well as provide better control, handling and overall driving experience. In this article, Pro Speed Racing explain what exactly sway bars are, and why they’re an important part of your car.

What is a sway bar?

At its simplest, a sway bar is a metal accessory that attaches to vehicles, designed as a torsion spring that effectively reacts to twisting movement. Sway bars join the wheels, steering system, spring shocks, rubber bushings, linkages and joints to form a comprehensive vehicle suspension system.

When vehicles perform turns, sway bars level the components and overall vehicle, preventing the sway that comes with sharp turns. They help the vehicle handle corners much easier and allow coaches or large vehicles to manage turns at an efficient pace. Sway bars vary from one vehicle and suspension system to another and are uniquely designed to optimise stability for each car.

Why are sway bars important?

Provides stable driving and levels-out components

As sway bars reduce the tilt and lean of a vehicle’s body, there are multiple reasons why they’re important. When vehicles turn corners or drive along an incline, the vehicle’s force is applied to the outside of the opposite side that the car is turning. With no intervention, the outside wheel lifts in reaction to this force.

Sway bars level out components and align the height of the tyres, which means the vehicle remains stabilised throughout the turn. They also help prevent parts from becoming misaligned and causing more severe and expensive problems.

Reduces the risk of vehicles rolling

Handling turns more effectively and maintaining height levels of components means that vehicles are much less likely to roll during turns. For tall vehicles and those with a high centre of gravity, they provide a grounding effect that makes driving a lot safer while protecting the vehicle.

Sway bars also offer more effective grip on the road because wheels are kept level, so without the capacity to lift, they produce better traction and control.

Enables consistent driving

Stabilising vehicles throughout turns not only allows for a more pleasant driver and passenger experience, but it increases handling and allows vehicles to maintain an appropriate speed. Maintaining speed throughout your drive and especially in busy environments provides consistency that increases safety.

It also protects and preserves many vehicle components, including brake pads by reducing the force brakes have to exert. By allowing cars to maintain speed throughout turns, this stability can also improve fuel efficiency as cars don't have to use more fuel to regain lost speed.
