If you’re looking to optimize your lifted vehicle’s suspension, upgrading the control arms is just one of many ways to go about this. However, purchasing a control arm can be a difficult, perplexing undertaking. Our objective is to make that task as simple and painless as possible. Here are the top things to look for when buying control arms.
What Are Control Arms?
Control arms, often known as “A arms,” are the backbones of your vehicle’s front suspension, connecting the front wheels to the rest of the vehicle. The wheel assembly is connected to one end, and the frame or chassis of your vehicle is connected to the other. The upper control arm attaches to the highest section of the steering knuckle or spindle, while the lower control arm attaches to the lowermost section, with both arms subsequently connecting to the vehicle’s frame.
What Is the Function of Control Arms?
Many automobile-owners may not be familiar with the term “control arms,” but they’re important parts of a vehicle’s suspension system, allowing the tires to gently rise and fall in a controlled manner. Without them, your ride would be unlikely to be pleasurable or safe. Most automobiles have one or two control arms per wheel on the front suspension and occasionally one on the rear suspension as well.
How To Choose Control Arms
You’ll know when the control arms start to fail. When you drive over a bump, the automobile may squeak or make a knocking sound, or it may pull to one side or the other. You may also notice that the tires are wearing unevenly. Control arm failure can occur as a result of regular wear and tear or because the bushing on the control arm has deteriorated.
When you’re looking for a replacement control arm assembly, you’ll want to look for materials that are both durable and affordable. Because this part is subjected to a lot of stress, you’ll want a long-lasting product.
- Decide on materials: Although cast-aluminum control arm components are lightweight and corrosion resistant, they buckle more easily when you drive over deep potholes. Cast-iron arms are typically wishbone shaped and extremely robust. Stamped steel arms were common on older autos; they’re less expensive, but they’re prone to rust.
- If you’re dealing with aftermarket parts, look for OEM (original equipment manufacturer)-compatible pieces. If you buy from a reliable vendor, high-quality aftermarket components can perform just as well as OEM parts.
- Choose a control arm assembly that’s powder coated or otherwise treated for corrosion resistance.
