A stabilizer bar, also known as a sway bar, is a component in a vehicle's suspension system. Its primary function is to reduce body roll during cornering, helping to keep the vehicle stable and improve handling. By connecting the left and right wheels, it distributes the forces experienced during turns, enhancing overall driving safety and comfort. Stabilizer bars are typically made of steel and come in various sizes and shapes, depending on the vehicle's design. They work in conjunction with other suspension parts, such as shock absorbers and coil springs, to provide a balanced ride. Proper maintenance of the stabilizer bar is essential for optimal vehicle performance.
