Abstract
A forged control arm for light trucks which is more durable than those currently available and which obviates the collection of debris. In a preferred manner, the forged control arm is formed with two leg portions joined by a common midsection and a support arm interconnecting the leg portions. A novel process for producing the control arm is also presented.
