Interesting Facts About the Global Control Arm Market

In North America, it’s commonly called a control arm.

In the U.K., it’s often referred to as a “wishbone.”

In some technical documents, you’ll see “suspension arm” or “A-arm.”

Despite different terminology, they all serve the same purpose: connecting the wheel hub to the vehicle chassis while allowing controlled movement.

2️⃣ Aluminum Is Replacing Steel in Many Vehicles

Traditionally, control arms were made from stamped steel.

Today, many OEMs are shifting to forged or cast aluminum control arms to reduce vehicle weight and improve fuel efficiency.

Premium brands like BMW and Mercedes-Benz widely use aluminum suspension components in their platforms.

3️⃣ EV Growth Is Reshaping Suspension Design

Electric vehicles are heavier due to battery packs.

This increases load requirements on suspension systems, including control arms.

Manufacturers such as Tesla use reinforced suspension geometries to handle torque and battery weight distribution.

4️⃣ Bushings Matter More Than Most People Think

A control arm is not just a metal part — its rubber or hydraulic bushings directly affect ride comfort, noise reduction (NVH), and steering precision.

In many aftermarket cases, failure happens in the bushing, not the arm itself.

5️⃣ Aftermarket Demand Is Stronger Than OEM in Some Regions

In developing markets (Middle East, Africa, South America), the replacement market is often stronger than new vehicle OEM supply.

Why?

Rough road conditions

Overloading

Extreme temperatures

Control arms are considered high-wear suspension parts in these regions.

6️⃣ Ball Joint Integration Changes Pricing Strategy

Some control arms come with pre-installed ball joints, while others are sold separately.

Integrated designs increase unit price but reduce installation time.

This affects how suppliers position products in different markets.

7️⃣ China Has Become a Major Exporter

China is now one of the largest exporters of suspension components, including control arms.

Improved forging technology and quality control systems have enhanced global competitiveness.

Factories supplying international clients must meet standards like ISO/TS certifications and strict material traceability.

8️⃣ Geometry Design Is Critical

Control arm length and angle directly affect:

Wheel alignment

Camber control

Handling stability

This is why OEM-level tooling precision is critical for export manufacturers.

9️⃣ Performance Market Is Growing

In the tuning and racing market, adjustable control arms are popular for:

Camber adjustment

Lowered vehicles

Drift and track use

The U.S., Japan, and Germany are major markets for performance suspension upgrades.
