Which suspension component helps to reduce body lean during cornering?

The stabilizer bar, also known as an anti-roll bar or sway bar, is specifically designed to reduce body lean in a vehicle during cornering. When a vehicle makes a turn, the weight of the car shifts, causing the body to lean towards the outside of the turn. The stabilizer bar helps to counteract this leaning motion by connecting the left and right wheels, transferring the force applied to one side of the suspension to the opposite side.

When the vehicle corners, the stabilizer bar twists, creating a force that pushes down on the outside wheel while lifting the inside wheel. This action helps maintain a more level ride and improves stability, allowing for better control and handling of the vehicle. Consequently, the stabilizer bar plays a crucial role in enhancing the overall performance and safety of the vehicle during dynamic driving conditions such as turns or curves.

Other components, while important to the overall functionality of the suspension system, do not primarily serve this role. Control arms primarily articulate the movement of the wheels and suspension, torsion bars are used for springing and support but do not directly manage body lean, and strut rods provide structural support to the suspension yet do not specifically reduce body roll during cornering.
