...or Lower Rear Swing Arm, Metal, Black, Painted Stock Image

The rear lower wishbone is a key element of the car's suspension, which connects the rear axle to the vehicle body. Its main task is to ensure stability and control while driving, transmitting forces and reactions related to wheel movement to the rest of the vehicle. The rear lower control arm is usually made of strong materials such as steel or aluminum, which provide it with the necessary strength and durability. It consists of a long arm that is attached to the car body and a link that is connected to the rear axle.
