Benefits of Control Arm
Shock Absorption
Control arms help effectively absorb shocks, which is crucial for ride comfort. When the vehicle drives over road irregularities, the control arms absorb the energy, preventing it from being transferred to the body. This results in a smoother ride, reducing discomfort for passengers.
Stability on Corners
Control arm kits also have a significant impact on vehicle stability when cornering. Control arms provide better tire grip on the road surface, allowing for more confident cornering. In the case of worn or low-quality control arms, the vehicle may exhibit excessive body roll, reducing safety and ride comfort.
Steering Precision
The condition of the control arms directly affects steering precision. Damaged or worn control arms can cause play in the suspension system, leading to imprecise steering and difficulty maintaining a straight driving line. Replacing worn control arms with new, high-quality components restores full control over the vehicle.
Responsible for maintaining control and alignment while allowing for the up and down travel of the suspension system while you're driving, control arms are key for maintaining your vehicle's directional stability, torque and traction.
The control arm connects your vehicle's wheels to the frame and helps maintain proper wheel alignment and movement to improve overall handling. Control arms have a direct effect on wheel travel, suspension durability and wheel alignment.
The Anatomy of Control Arm
Found on virtually all road-going suspension systems, control arms are located at the front axle at each of the two front wheels. They are comprised of either stamped steel, cast iron, or cast aluminum as their primary material. Steel and iron control arms deliver strength, sturdiness, and the ability to resist damage.
Control arms are typically A-shaped, L-shaped, or wishbone-shaped, but designs differ from vehicle-to-vehicle based on suspension geometry. These components have connection points at each end for attaching a wheel's steering knuckle to the vehicle frame.
At the frame or body, the control arm connects to a hinge by bolts and bushings. These bushings guard against metal-on-metal contact when the arm is moving up and down with the wheels.
At the steering knuckle end, the control arm connects via ball joint to allow smooth wheel movement in all directions. The ball joint allows the steering knuckle to pivot and gives the wheels the ability to turn while the vehicle is in motion.
Control Arm Material
Stamped Steel
Steel is a good material. In addition to being sturdy, it easily flexes and won't easily break or crack under the vehicle's weight or impact. Steel arms also cost less to manufacture, which makes them an inexpensive option.
Cast Aluminum
Aluminum weighs comparatively less and will not introduce unnecessary weight. It also does not rust and can last longer in wet or salty conditions. It also absorbs vibration better than the other materials.
Cast Iron
Cast iron is more rigid than steel and aluminum and can support heavier loads. Cast-iron arms are, therefore, mainly used in heavy-duty vehicles like trucks. The material is usually coated to protect it against damage if you drive in wet conditions.
