Turn to Delphi Technologies for steering & suspension.
Our control arms and track control arms are the real deal. As a critical element of a vehicle’s design and an integral part of the suspension system, you've got to choose an OE quality control arm. That's why you can turn to Delphi Technologies for reliable steering & suspension parts.
Why should you trust Delphi Technologies for control arms?
- Our control arms undergo 100% crack detection and ultrasonic flaw detection tests to ensure materials match OE specifications.
- Robot welded for consistent performance and quality.
- Anti-corrosion protection applied to each part.
- We test our parts to the extreme, from every angle, for reliable performance at temperatures below -40°F and over 248°F.
Turn to Delphi Technologies for imports.
In the US and Canadian aftermarket, we’re best known for our fuel management program, but in Europe we are one of the market leaders in steering and suspension. And of course, we’re known all over the globe for our rich OE heritage. Now we’re bringing our world-class steering portfolio to North America, and we’re focused on imports.
Applications include Acura, Audi, BMW, Daewoo, Fiat, Honda, Hyundai, Infiniti, Isuzu, Jaguar, Kia, Land Rover, Lexus, Mazda, Mercedes-Benz, Mini Cooper, Mitsubishi, Nissan, Porsche, Saab, Scion, Smart, Subaru, Suzuki, Toyota, Volkswagen, and Volvo. So whether you’re a technician or a DIYer, you can trust Delphi Technologies steering & suspension parts for your European and Asian vehicles.
What control arms do:
Help control the motion of the wheels and connect the suspension to the vehicle structure.
Connecting the spindle, hub or knuckle and wheel to the vehicle’s chassis, the control arm is a critical part of any vehicle’s steering and suspension system. Also known as an A arm, it allows the wheels to move up and down, while preventing forward and rearward movement and maintaining directional input from the driver. So, when the steering wheel is turned, the wheels follow suit.
When control arms fail:
If a control arm comes loose or is bent, it can be dangerous to drive. This can happen after collisions, hitting pot holes or curbs, etc.

Tested at every turn.
We test our parts to the extreme, from every angle. All our control arms undergo rigorous dimensional, material, durability and performance tests, designed to replicate the very same stresses the part will experience on the road. For example, every part is tested on our three axis test rig so all three forces can be analyzed simultaneously; braking force, cornering force and suspension travel movement. And up to 250,000 cycles. Watch this video to see the stresses our control arms withstand in three-axis testing.
We also test their resilience to extreme environmental conditions and corrosive materials. Our purpose-built environmental chamber tests to temperatures as low -40°F and up to 248°F. And our control arms are exposed to 720 hours of salt spray, to evaluate the effect of salt on bushings adhesion. So, you can choose a Delphi Technologies control arm with confidence, knowing they’ll perform, even under the harshest conditions.
Traditional phosphate coatings, applied by dipping or spraying have proven to be ineffective. That’s why our water-based cataphoretic coating uses electrical currents to apply the paint. The environmentally friendly procedure offers increased corrosion protection from salt, dirt and water. And is longer lasting too, providing up to 10 years’ protection.
Why does my control arm look different on this car?
Control arms can look very different from vehicle to vehicle. There are also multiple types of suspension systems for different types of vehicles and desired handling experiences. Here are the three most common for light-duty vehicles.
Below is an example of the Double Wishbone Suspension System, or Short-Long Arm Suspension (SLA).
Below is an example of the MacPherson Strut Suspension System.
Below is an example of the Multilink Suspension System.
Rear left lower forward? Front right upper rearward?
Naming conventions of control arm positions can be complicated, especially when some modern vehicles can have more than a dozen different control arms, like those with a multilink system, above. Make sure you get the right part the first time. The Delphi Auto Parts App has a simple tool to figure out the location on the vehicle of the part you are replacing and what its position name is. Then, just visit our catalog to find out the Delphi part number for your application.
