What is a sway bar on a car?

A sway bar, also known as a stabilizer bar or anti-roll bar, is a component of a car's suspension system that helps reduce the body roll or sway of a vehicle during cornering or other maneuvers. It works by connecting the left and right wheels of the car together through a torsion spring, which resists the tilting motion of the vehicle when turning.

Sway bars are typically made of steel and come in various sizes and shapes, depending on the specific requirements of the vehicle. They are mounted to the chassis of the car and connected to the suspension components using end links.

By reducing body roll, sway bars help improve the stability and handling of a vehicle, especially during sharp turns or sudden maneuvers. They also help distribute weight more evenly across all four wheels, resulting in better traction and control.

Overall, sway bars play an important role in enhancing the driving dynamics and safety of a vehicle, making them a common feature in most modern cars.
