What Does a Sway Bar Do

What is a sway bar?

A sway bar, also known as an anti-roll bar or stabilizer bar, is a suspension component that connects the left and right wheels of a vehicle. It helps reduce body roll and improve stability during cornering. By transferring weight from the inside wheel to the outside wheel, the sway bar helps minimize body lean and improve handling.

The sway bar works by twisting from side to side as the vehicle turns. This torsional movement creates resistance against the body roll, which helps keep the car level. The stiffness of the sway bar determines how much it can resist this movement. A thicker sway bar will provide more resistance and less body roll than a thinner one.

One unique aspect of sway bars is that they do not contribute to ride comfort or straight-line stability. Their main purpose is to improve handling during turns. Sway bars can be adjusted or replaced with aftermarket options to fine-tune a vehicle’s handling characteristics.

According to Motor Trend, “Properly designed and installed anti-roll/bar suspension systems can make any car handle better.” Why did the car’s suspension feel so stable? Because the sway bar decided to take charge and keep things in line.
