Product Advantage
1. High-Strength Material & Precision Craftsmanship
This high-performance A2904110 ball joint is made of high-strength forged steel, a material selected after 15+ years of automotive parts R&D. The forging process ensures 30% higher tensile strength than ordinary cast steel, while the surface is treated with electrophoretic coating. It passed a 500-hour salt spray test, maintaining corrosion resistance even in humid or dusty environments. This craftsmanship eliminates premature wear, making it a reliable automotive ball joint replacement for long-term use.
2. Dual International Quality Certifications
As an ISO 9001 certified Lifan ball joint, it also meets TS 16949 automotive quality standards—two certifications that require strict compliance in raw material inspection, production process control, and final product testing. Each unit undergoes a 10,000-cycle fatigue test (simulating continuous steering operations) and a 200N·m torque test, with a 100% qualification rate before leaving the factory. These certifications ensure it aligns with global automotive part quality benchmarks.
3. Extended Service Life Exceeding Industry Averages
Backed by real-world operational data, this A2904110 ball joint delivers a service life of 20,000+ miles under normal driving conditions—25% longer than the industry average for comparable products. The internal bearing uses high-density PTFE lubricant, which reduces friction by 40% and avoids the need for frequent re-lubrication. This extended lifespan cuts down on replacement frequency and maintenance costs for end-users.
4. High Load-Bearing Capacity for Stable Performance
It features a static load capacity of 3,000+ lbs, easily handling the vertical and lateral forces generated during acceleration, braking, or rough road driving. The ball stud is heat-treated to HRC 58-62 hardness, preventing deformation even under sudden heavy loads. This load-bearing capability ensures consistent steering responsiveness and suspension stability, critical for safe driving.
5. 15+ Years of OE-Grade Manufacturing Experience
Our factory has 15+ years of experience in producing OE-grade automotive suspension parts, with a dedicated production line for Lifan ball joints that outputs 50,000+ units annually. We use 3D optical measuring instruments to control dimensional tolerance within ±0.02mm, ensuring perfect fit with original mounting points. This experience guarantees the product’s compatibility and reduces installation errors for repair shops or end-users.

Product Uses
Here are specific application scenarios of Ball Joint:
1. Daily Urban Driving
Ideal for vehicles used in daily commuting, where frequent steering (at intersections, parking lots) and stop-and-go traffic are common. The PTFE internal bearing reduces steering friction by 40%, ensuring smooth handling. Its 20,000+ mile service life also matches the annual mileage (10,000–15,000 miles) of most urban drivers, avoiding frequent replacements.
2. Long-Distance Highway Driving
Suitable for vehicles traveling long distances on highways, where stable suspension performance is critical. With a static load capacity of 3,000+ lbs, it handles continuous vertical forces from high-speed driving. Its -40℃ to 120℃ operating range also adapts to temperature changes across regions, maintaining reliability in both cold and hot climates.
3. Rough Road Conditions (Rural/Dirt Roads)
Perfect for vehicles navigating unpaved rural roads or construction zones with potholes. The forged steel (40Cr) housing resists impact damage, while the electrophoretic coating (tested to 500-hour salt spray) prevents rust from mud or water. This durability reduces wear caused by gravel and vibrations, extending service life in harsh environments.
4. Professional Auto Repair Shop Replacements
A top choice for repair shops focusing on reliable aftermarket parts. It meets OE-level dimensional standards (tolerance ±0.02mm), with 100% fit verification completed. Shops can reduce installation time by 15% (vs. non-standard parts) and lower return rates—backed by our 15+ years of OE-grade manufacturing experience.
5. Fleet Vehicle Maintenance
Ideal for corporate fleets (logistics, service vehicles) that require minimal downtime. Its 25% longer service life than industry averages cuts maintenance frequency. The maintenance-free design (no re-lubrication needed) also saves fleet managers time and labor costs, aligning with efficient fleet operation needs.
Product Operate Guide
We recommend professional technicians install this part (per ISO 18328 standards) for safety. First, inspect the ball joint for damage; then remove the old part with standard auto repair tools. When installing, use a torque wrench to fasten mounting bolts to 200 N·m (matches our torque test data). After installation, test steering smoothness—no stiffness or abnormal noise means proper fit. Check it every 5,000 miles to maintain performance.
