Control Arms and Wishbones

Connecting the spindle, hub or knuckle and wheel to the vehicle’s chassis, the control arm or wishbone - depending on the type of suspension - 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. That’s pretty important, so you’ll want to fit a quality steering brand that always performs to the same standard as OE. Just like Delphi.

Quality counts

As well as affecting the vehicle’s handling, comfort and safety, lower quality steering and suspension parts can accelerate wear and tear on other parts of the vehicle, causing unnecessary expense. That’s why every one of our control arms and wishbones is designed, engineered and manufactured to meet exacting OE standards at our state-of-the-art production facilities.

Proven performance

All our control arms and wishbones 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 analysed simultaneously; braking force, cornering force and suspension travel movement. And up to 250,000 cycles. Just to be sure.

Tested to the extreme

We also test their resilience to extreme environmental conditions and corrosive materials. Our purpose-built environmental chamber tests to temperatures as low -40°C and up to 120°C. And our control arms are exposed to 720 hours of salt spray, to evaluate the effect of salt on rubber-to-metal adhesion. So, you can fit with confidence, knowing they’ll perform, even under the harshest conditions.

Cataphoretic coating

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 ingress. And is longer lasting too. Providing up to 10 years’ protection.

Three-year warranty

Available in UK only. Thanks to our all-encompassing approach to testing, we know our control arms and wishbones will perform just like the OE. Day-in, day-out. That’s why every Delphi steering part comes with an extended three-year or 36,000-mile warranty. Demonstrating our commitment to the very highest quality standards and giving you added peace of mind.

The complete solution

For a fast, efficient, and of course, complete steering repair, we also provide a range of suspension kits. Each kit comes with the key components, including control arms, ball joints and bushings, as well as fasteners, where needed. So, you have everything at hand for a best-practice steering repair, and at a more attractive price too.
