Product Introduction
A21-2919110 Precision-engineered OE-matching Corrosion-resistant Car Control Arm for Chery
Our Control Arm for Chery is a high - quality, precision - engineered automotive part. As a key component of the suspension system, it plays a crucial role in connecting the wheel hub to the vehicle's chassis.
Crafted from durable materials like high - strength steel or lightweight yet sturdy aluminum alloy, this control arm offers excellent resistance to wear and tear. It effectively absorbs shocks and vibrations from the road surface, ensuring a smooth and comfortable driving experience. The control arm also helps maintain proper wheel alignment, which is essential for optimal vehicle handling, accurate steering response, and even tire wear. With strict quality control and industry - standard manufacturing processes, our product guarantees reliable performance, meeting and exceeding the demands of Chery vehicle owners worldwide.
Product Advantage
1. High-Strength Material & Precision Forging Process
Our Chery control arm is made of 45# high-tensile steel (tensile strength ≥ 600MPa) through 3-stage precision forging. This process reduces material internal stress by 40% compared to ordinary casting, ensuring the arm resists deformation even under 2.5-ton continuous load. The surface undergoes electrophoretic coating (thickness 8-12μm) with salt-spray resistance over 500 hours, effectively preventing rust in harsh environments.
2. 100% OE-Matching Design & Drop-In Installation
Each OE-matching control arm is developed based on original Chery parts’ 3D scanning data (error ≤ 0.05mm). It perfectly fits the original mounting positions, requiring no drilling or modification during installation—saving mechanics 30% of installation time. The bushing uses high-density polyurethane (Shore hardness 70±5A), matching the original damping coefficient to avoid abnormal noise.
3. Stability-Enhancing & Vibration-Dampening Performance
Equipped with a dual-bearing structure, the control arm reduces steering play by 65% and improves vehicle stability at high speeds (tested to reduce body sway by 25% on uneven roads). Its integrated shock-absorbing design filters 80% of road vibrations, enhancing driving comfort while protecting other suspension components.
4. ISO/TS 16949-Certified Quality Control
Our production strictly follows ISO/TS 16949 automotive quality standards, with 100% full-inspection before delivery (including dimensional testing, load testing, and fatigue testing). The control arm passes 200,000-cycle fatigue tests (equivalent to 80,000km driving) without failure, far exceeding the industry average of 150,000 cycles.
5. Long-Lasting Durability & Low Maintenance
The heavy-duty Chery control arm has an average service life of 5-8 years (2-3 years longer than ordinary aftermarket parts), thanks to wear-resistant bushings and corrosion-resistant steel. Its maintenance-free design eliminates the need for regular lubrication, reducing owners’ long-term use costs by approximately 40%.
6. Professional R&D Support & Customization
With a 15-year-experienced R&D team specializing in Chery suspension parts, we update the control arm design annually based on 10,000+ user feedback data. We also offer customization for special usage scenarios (e.g., off-road, commercial vehicles) while maintaining OE-level compatibility and performance.

Product Uses
Here are specific application scenarios of Control Arm:
Daily Urban Commuting
Frequent starts, stops, and turns in cities put constant stress on suspension. Our Chery control arm, with 80% vibration-dampening, reduces jolts from potholes and speed bumps, ensuring stable steering and smooth rides for daily commutes, trusted by 20,000+ urban drivers yearly.Complex Road Conditions (Mountains/Rural Areas)
On gravel, muddy or hilly roads, the arm’s 600MPa high-tensile steel resists deformation. Its 2.5-ton load-bearing capacity handles uneven terrain, lowering suspension failure risks by 40% vs ordinary arms, ideal for drivers in non-urban areas.Aftermarket Maintenance & Replacement
When original control arms wear (avg 3-4 years), our OE-matching arm fits 99.5% Chery models. Mechanics save 30% installation time (no modifications), and it meets ISO/TS 16949 standards, chosen by 500+ auto repair shops globally.Commercial Vehicle Operations
For Chery-based commercial vehicles (logistics, delivery), the arm’s 5-8 year service life cuts replacement frequency. Its corrosion-resistant coating (500h salt-spray test) endures frequent outdoor use, reducing fleet maintenance costs by 35%.Extreme Temperature Environments
Operating in -40℃ to +120℃, it performs stably in frigid winters (e.g., high latitudes) and hot summers. The polyurethane bushing avoids hardening/cracking, ensuring reliable suspension, certified by TÜV for extreme climate use.Suspension Upgrade for Driving Safety
For drivers prioritizing safety, upgrading to our arm enhances stability by 25% (tested on winding roads). It maintains wheel alignment, reducing tire wear by 20%, a cost-effective upgrade recommended by auto suspension experts.
Product Operate Guide
Pre-Installation Check
Verify the arm matches your Chery’s OE specs (part number/ dimensions). Clean mounting areas—debris causes 30% of post-install noise. Check bushings for cracks (replace if hardened).
Installation Steps
Use professional tools (torque wrench: 80-100 N·m). Align arm with chassis/hub; tighten bolts sequentially. Avoid over-tightening (damages threads). Test steering after fitting—ensure no play.
Daily Use & Maintenance
No regular lubrication needed (maintenance-free). Inspect annually: look for rust (500h salt-spray resistance ensures durability) or loose bolts. Replace after 5-8 years (or 80,000km) for safety.
