Product Introduction
A21-2909020BB High-Tensile Precision-Machined Durable Car Control Arm for Chery
Our Chery-specific control arm is built on 15+ years of suspension component expertise, meeting ISO 9001 and IATF 16949 standards. Made with heat-treated high-strength steel (tensile strength ≥600MPa), it lasts 30% longer than industry averages.
Core functions: Stabilize vehicle handling, absorb road vibrations, and maintain wheel alignment for safe rides. With OEM-level precision (tolerance ≤0.05mm), it enables drop-in replacement—no extra mods needed. Trusted by 500+ global auto repair shops.
Product Advantage
1. High-Strength Forged Steel Material for Superior Durability
Our Control Arm for Chery is crafted from 42CrMo forged alloy steel—a material with 1200MPa tensile strength, 30% higher than ordinary carbon steel. This ensures exceptional resistance to bending and fatigue even under long-term heavy loads (e.g., rough road conditions). With a salt-spray test result of 500+ hours, it effectively resists rust and corrosion, extending the service life to 80,000+ kilometers. It’s the ideal choice for durable Chery suspension control arm solutions.
2. Precision CNC Machining for Zero-Fitment Issues
Each control arm undergoes 5-axis CNC machining, achieving a dimensional tolerance of ±0.02mm—far exceeding industry standards (±0.1mm). The ball joint socket and mounting holes are processed in one cycle, ensuring 100% alignment with Chery’s original chassis specifications. This eliminates fitment gaps and abnormal noises, reducing post-installation adjustment time by 60%. It’s a benchmark for precision Chery control arm manufacturing.
3. High-Elasticity Polyurethane Bushing for Smooth Driving
Equipped with imported polyurethane bushings (Shore A hardness: 85±3), the control arm absorbs 40% more road vibrations compared to rubber bushings. It maintains stable performance in extreme temperatures (-40℃ to 120℃) without hardening or cracking. This not only enhances driving comfort but also reduces wear on adjacent suspension parts (e.g., stabilizer links), lowering overall maintenance costs for users of Chery aftermarket control arms.
4. 100% Factory Pre-Assembly & Endurance Testing
Before leaving the factory, every control arm undergoes a 30,000-cycle swing test (simulating 5 years of daily use) and a 2000N load-bearing test—all in compliance with ISO/TS 16949 automotive quality standards. We achieve a 99.8% pass rate in final inspections, supported by a 2-year/40,000km warranty. This demonstrates our commitment to reliable Chery suspension components.
5. Lightweight Design for Fuel Efficiency
By optimizing the arm’s structural design (adopting a hollow ribbed structure), we reduce the weight by 15% (from 2.2kg to 1.87kg) without compromising strength. This lightweight upgrade lowers the vehicle’s unsprung mass, improving handling responsiveness and reducing fuel consumption by approximately 0.3L/100km. It’s a cost-effective high-performance Chery control arm for eco-conscious drivers.
6. Global Supply Chain & Timely Delivery
As a professional manufacturer with 15 years of experience in automotive suspension parts, we supply Chery control arms to 40+ countries (e.g., Europe, Southeast Asia, South America). Our 10,000㎡ warehouse stocks 50,000+ units, enabling 48-hour delivery for standard models. We also offer custom OEM/ODM services (minimum order quantity: 500 units) to meet diverse market demands, backed by 24/7 after-sales support.

5. Extreme Temperature Environments
Adapts to -40℃ cold regions (e.g., Northern Europe) and 120℃ hot areas (e.g., Middle East). The bushing retains elasticity in extreme temps, avoiding suspension failures. Certified by SGS for stable performance in 90% of global climate zones.
6. Aftermarket Replacement & Repair
A top choice for auto repair shops and aftermarket distributors. With direct OE fitment (no modification needed), it shortens repair time by 60% (from 2hrs to 48mins). 85% of professional mechanics recommend it for reliable Chery suspension replacements.
Product Operate Guide
Pre-installation Check: Verify the control arm’s surface (no rust/deformation) and bushing flexibility. Match OE part number to ensure fitment—avoids 90% of installation issues (per SAE J2530 standards).
Installation Steps: Use a torque wrench (55-60 N·m) to fasten mounting bolts. Tighten in crisscross order; avoid over-torque (prevents thread damage). Test suspension swing post-install (no abnormal noise = success).
Post-install Care: Inspect after 500km of use (check bolt tightness). Clean with neutral detergent (protects anti-corrosion layer). Follow this to extend service life to 80,000+ km (as per our durability test data).
