Lower control arms are essential components of a vehicle's suspension system. They connect the vehicle's chassis to the wheels, allowing for controlled movement during driving. This helps maintain stability and improves handling by managing the wheel's alignment and movement over bumps and turns. These arms are typically made of metal and are designed to withstand significant forces. They work in conjunction with other suspension parts, such as upper control arms and shock absorbers, to provide a smooth ride. Proper functioning of lower control arms is crucial for tire wear and overall vehicle safety.
