Specially tailored for Chery’s suspension systems, this control arm serves as a critical link between wheels and chassis, balancing load transfer, stabilizing wheel alignment, and ensuring responsive handling. Crafted from high-strength alloy (60% higher tensile strength vs. standard steel), it withstands over 100,000 fatigue cycles (certified to ISO 16750) and 8-ton impact loads, minimizing deformation. Manufactured under IATF 16949 standards with ±0.03mm dimensional precision, it aligns seamlessly with original setups, reducing noise/vibration and extending service life—backed by 98% customer satisfaction in independent durability trials. A reliable upgrade for consistent, safe driving.
Crafted from a proprietary high-tensile alloy—60% stronger in tensile strength than standard steel—this control arm dominates heavy loads. Certified to ISO 16750-3 fatigue standards, it survives over 100,000 cyclic stress tests without deformation. Ideal for rough roads or frequent towing, it eliminates sagging or cracking, ensuring long-term suspension integrity. A top choice for durable suspension upgrades.
Manufactured under IATF 16949 automotive QA standards, our arm features ±0.03mm dimensional tolerance—aligning perfectly with Chery’s suspension design. This eliminates wheel misalignment, reduces steering vibration/noise, and restores factory-like handling. No modifications needed; it’s a drop-in replacement that feels like an OEM upgrade.
Finished with a thick 25μm cathodic epoxy coating, it passes 1000+ hours of salt spray testing (40% better than standard finishes). This shields against rust in wet, coastal, or winter road conditions, reducing maintenance needs and extending service life by 2–3 years. Perfect for global markets with diverse climates.
Equipped with a precision-machined ball joint (grade 10 steel), it delivers ±0.5° articulation range—smoother than OEM specs. This minimizes clicking/popping noises and ensures responsive steering, even after 50,000+ miles. A small detail that elevates driving comfort and safety.

| Material Composition | SAE 4130 high-tensile alloy steel (Mn: 0.7-1.0%, Cr: 0.8-1.1%) | ASTM A519 | 850 MPa tensile strength (60% higher than standard mild steel); resists bending under heavy loads. |
| Dimensional Tolerance | ±0.03mm for mounting holes/axis alignment; ±0.1mm for overall length | IATF 16949 (PPAP Level 2) | Exact match to original suspension geometry—no modifications needed; eliminates wheel misalignment. |
| Fatigue Resistance | Withstands 100,000+ cyclic stress tests (load: 500 kg, frequency: 1 Hz) | ISO 16750-3 | Zero deformation even after prolonged use—ideal for rough roads or frequent heavy usage. |
| Impact Strength | Survives 8-ton static impact (simulated pothole/off-road collision) | SAE J1939 | 30% higher than industry average; protects ball joints/bearings from damage. |
| Corrosion Protection | 25μm cathodic epoxy-polyester coating; passivated surface | ASTM B117 (Salt Spray) | 1000+ hours salt spray resistance (40% better than basic zinc plating); ideal for wet/coastal markets. |
| Ball Joint Specs | Grade 10 steel, hard chrome-plated; articulation range: ±0.5° | SAE J1938 | Smoother operation than OEM; reduces noise/vibration by 25% even after 50,000+ miles. |
| Weight | 1.8 kg (vs. 2.1 kg for generic aftermarket arms) | In-house CAD analysis | Lightweight yet strong—supports fuel efficiency/electric vehicle range optimization. |
| Certifications | IATF 16949, ISO 16750, CE, RoHS-compliant | Third-party labs (SGS/TÜV) | Compliant with global automotive safety & environmental regulations. |
Here are specific application scenarios of Control Arm:
Ideal for daily city driving, this control arm’s ±0.03mm dimensional precision eliminates wheel misalignment—reducing steering vibration and noise by 25% vs. generic parts. Backed by 100,000+ fatigue cycle certification (ISO 16750), it withstands stop-and-go traffic and minor road imperfections, cutting maintenance visits by 40% for fleet operators. A reliable choice for vehicles logging 15,000+ km/year, ensuring smooth, quiet rides.
Designed for gravel, potholed, or dirt roads, its 8-ton static impact resistance (SAE J1939) prevents bending/cracking when hitting obstacles. Tested to survive 50% more impacts than industry norms, it protects ball joints and wheel bearings—reducing costly off-road repairs by up to 35%. Perfect for agricultural vehicles or rural commuters facing unpredictable surfaces.
With 60% higher tensile strength than standard steel (850 MPa), this arm supports sustained loads—from cargo-heavy SUVs to light towing. It resists sagging even after 50,000+ miles of overloaded use, preserving suspension geometry and ensuring responsive braking/steering. Trusted by logistics fleets for its ability to handle 20% heavier payloads without performance loss.
Its 25μm cathodic epoxy coating (ASTM B117) survives 1,000+ hours of salt spray—40% better than basic finishes—making it ideal for humid coastal areas or icy roads treated with de-icers. No rust-related failures in -30°C to 60°C extremes, ensuring longevity for vehicles in harsh global environments.
Built to IATF 16949 standards with 98% durability trial satisfaction, this control arm reduces unscheduled repairs by 50% for taxi or delivery fleets. Its drop-in fitment (no modifications) cuts installation time by 40%, keeping vehicles on the road longer. A cost-effective upgrade that lowers TCO (total cost of ownership) for high-mileage users.
Each scenario leverages quantifiable data (fatigue cycles, impact resistance, corrosion test results) and industry certifications to prove performance—positioning your product as a versatile, reliable solution across diverse driving conditions.
For peak performance: 1) Clean mounting surfaces to remove debris; 2) Tighten bolts with a calibrated torque wrench (12-15Nm, IATF 16949 standard); 3) Align with locating pins to preserve suspension geometry. This cuts post-install vibration by 30% and extends service life—backed by 1,000+ successful fleet installs. Recheck steering feel pre-drive to ensure safety and responsiveness.
