Product Introduction
T11-2919030 High-Tensile Long-Lasting OEM-Spec Control Arm for Chery
The control arm for Chery is a pivotal component in the vehicle's suspension system. Its primary function is to connect the wheel to the vehicle's frame. By doing so, it enables the wheel to move smoothly up and down in response to uneven road surfaces, such as bumps and dips, ensuring a comfortable ride.
Made from high-strength materials like steel or aluminum, it offers durability and can withstand significant stress. This control arm also plays a crucial role in maintaining wheel alignment, which is essential for stable steering and even tire wear. With precise engineering, it meets the high standards of Chery vehicles, providing reliable performance for a long time.
Product Advantage
1. High-Strength Material & Long-Lasting Durability
Adopting heavy-duty 45# carbon steel (tensile strength ≥ 600MPa) for the main body, our control arm for Chery undergoes quenching and tempering treatment. This process enhances surface hardness to HRC 30-35, ensuring it resists deformation even under 500,000+ times of road impact (tested per ISO 18797 standard). The material’s corrosion resistance is 3x higher than ordinary steel, adapting to harsh environments like coastal areas or cold regions.
2. Precision Engineering for Stable Wheel Alignment
Equipped with a CNC-machined ball joint (tolerance ≤ 0.02mm), the control arm maintains accurate wheel positioning. After 10,000km road tests, the wheel alignment deviation is controlled within ±0.5°, effectively reducing uneven tire wear (saving 15% of tire replacement costs annually for users). It perfectly matches the original suspension system, avoiding abnormal noise caused by poor fitment.
3. High-Performance Rubber Bushing for Smooth Ride
The integrated rubber bushing is made of EPDM material with Shore A hardness 65±5. It absorbs 80% of road vibrations (tested at 20-200Hz frequency), significantly improving driving comfort. The bushing’s aging resistance exceeds industry standards—after 3 years of use, its elasticity retention rate remains over 90%, avoiding the need for frequent replacements.
4. Strict Quality Control & Authority Certifications
Each control arm passes 12 inspection procedures, including load-bearing test (max load 1200N), fatigue test, and salt spray test (500 hours without rust). We hold ISO/TS 16949 (automotive quality management system) certification, and our products have a defect rate of less than 0.03% (backed by 500,000+ units of annual sales data). This ensures consistent reliability for global customers.
5. Easy Installation & Cost-Effective After-Sales
Designed with the original vehicle’s mounting points in mind, the control arm can be installed in 30 minutes (no need for modified tools). We provide a 24-month/60,000km warranty—10% faster than the industry average response for after-sales issues. For bulk orders, we offer technical support for installation guidance, reducing maintenance costs for repair shops.

Product Uses
Here are specific application scenarios of Control Arm:
1. Urban Daily Commuting
Ideal for daily travel on urban roads with frequent stops, starts, and small potholes. Its EPDM rubber bushing absorbs 80% of road vibrations (tested at 20-200Hz), reducing driver fatigue. The CNC-machined ball joint ensures stable steering, adapting to dense traffic flow.
2. Suburban & Rural Roads
Suitable for suburban/rural roads with uneven surfaces and gravel. Made of 45# carbon steel (tensile strength ≥600MPa), it withstands 500,000+ road impacts (ISO 18797 standard). Resists deformation, ensuring smooth driving even on bumpy sections.
3. Long-Distance Highway Driving
Perfect for long highway trips (1000+ km). Maintains wheel alignment deviation ≤±0.5° after 10,000km tests, reducing uneven tire wear by 15%. The 1200N max load-bearing capacity (ISO 10326-1) ensures stability at high speeds.
4. Harsh Climate Environments
Adapts to coastal (high humidity) and cold (-40℃) regions. 500-hour salt spray test (ISO 9227) proves no rust; the bushing works normally at -40℃~+120℃. Avoids corrosion and aging, ensuring year-round reliability.
5. Fleet & Commercial Vehicle Operations
For commercial fleets (frequent use). With ≤0.03% defect rate (500,000+ annual sales) and 24-month/60,000km warranty, it reduces maintenance frequency. 30-minute quick installation cuts downtime for fleet managers.
Product Operate Guide
Installation: Use standard auto repair tools (no modifications needed). Align the control arm with original mounting points, fasten bolts to 35-40 N·m torque (per ISO 898-1), and finish in ≤30 minutes. Post-installation, check wheel alignment (deviation ≤±0.5°).
Daily Use: Avoid overloading (max dynamic load 800N). For harsh roads, inspect rubber bushings quarterly—replace if cracks appear (elasticity retention <90%).
Maintenance: After 30,000km, lubricate the ball joint (use lithium-based grease). Follow the 24-month/60,000km warranty for defective parts.
