Control arms are essential components of a vehicle's suspension system. They connect the chassis to the wheels, allowing for controlled movement and stability while driving. By managing the wheel's vertical motion, control arms help maintain proper alignment and improve handling, contributing to a smoother ride. There are typically two types of control arms: upper control arms and lower control arms. Each type plays a specific role in supporting the vehicle's weight and absorbing shocks from the road. Properly functioning control arms are crucial for safety and performance, as they directly affect tire wear and overall driving dynamics.
