The Lower Control Arm is formed by a rigid metal structure, which is a metal bar that connects to the front or rear spindle of the vehicle and to the chassis. It is a fundamental part of the suspension system and can be made of steel or aluminum, often taking the shape of an "L" or "U". Each wheel has a control arm depending on the vehicle's design, and sometimes, some cars have both upper and lower arms.
