A subframe is a structural component in an automobile or other vehicle that supports the weight of the body and suspension components. It typically consists of a rigid, welded-together structure made from steel or aluminum, with attachment points for various parts such as shock absorbers, springs, control arms, and other suspension components. The subframe also provides support for the vehicle's engine, transmission, and other mechanical systems. In some vehicles, it may also serve as a mounting point for the body panels or frame rails. Overall, the subframe plays an important role in providing structural integrity to the vehicle while allowing for smooth handling and ride quality.
