What are Control Arms?

Control arms, also known as suspension arms or A-arms, are essential parts of a vehicle's suspension system. They connect the chassis to the wheel hubs, allowing for controlled vertical movement of the wheels. Typically, a vehicle has upper and lower control arms, and their primary function is to stabilize the vehicle during cornering and provide alignment to the wheels. A well-functioning control arm is crucial for optimal handling, ride quality, and tire wear.

How Do Control Arms Affect Ride Quality?

Control arms play a direct role in how a vehicle handles on the road. If control arms are worn or damaged, you may experience poor ride quality, which can manifest as excessive vibrations, steering difficulties, or uneven tire wear. An efficient suspension system with intact control arms promotes better handling during acceleration and cornering, leading to a more enjoyable driving experience.
