Product Advantage
1. Authoritative Quality Certifications & Strict Quality Control
This heavy-duty ball joint is fully compliant with ISO 9001 and IATF 16949 standards—two most recognized certifications in the auto parts industry. Our production line adopts a 6-step quality inspection process, from raw material screening to finished product testing, achieving a 99.9% qualification rate. Every unit is sampled and verified by third-party testing institutions, ensuring it meets international quality benchmarks for automotive chassis components.
2. Premium Materials for Exceptional Durability
The 2904150XKZ16A Ball Joint features a high-strength SCM435 alloy steel housing, which enhances impact resistance by 30% compared to ordinary carbon steel. Its internal bearing uses wear-resistant POM (polyoxymethylene) material, tested to reduce friction coefficient by 0.02 and extend service life to 50,000+ kilometers. The surface is treated with electrophoretic coating, providing corrosion resistance that passes 500-hour salt spray tests—ideal for harsh environmental conditions and long-term use as a wear-resistant ball joint.
3. Rigorous Performance Testing for Stable Operation
We subject each ball joint to three core performance tests: 1) Static load test: Withstands 3,000N vertical load without deformation, far exceeding the industry’s 2,500N standard. 2) Fatigue cycle test: Completes 10,000+ reciprocating motion cycles at 15° swing angle, maintaining smooth operation without jamming. 3) Temperature resistance test: Performs normally in the range of -40℃ to 120℃, adapting to extreme cold or hot climates. These tests guarantee the high-performance ball joint remains stable under various driving conditions.
4. Direct-Fit Design for Easy Installation & High Compatibility
Designed with precise dimensional accuracy (tolerance within ±0.05mm), this ball joint is a direct replacement for original parts, eliminating the need for modification during installation. It reduces installation time by 40% compared to universal-fit alternatives, saving labor costs for repair shops. With 99.8% compatibility with target vehicle platforms, it ensures a perfect match with existing suspension and steering systems, avoiding fitment issues common in low-quality heavy-duty ball joint products.
5. Reliable After-Sales Support Backed by Data
We offer a 24-month/40,000-kilometer warranty for this ball joint—backed by our 0.3% annual replacement rate data (lower than the industry average of 1.2%). Our after-sales team provides technical support within 8 hours for any installation or performance questions, and we maintain a 98% customer satisfaction rate based on 5,000+ post-purchase feedbacks. This commitment ensures customers feel secure when choosing our automotive chassis components.

Product Uses
Here are specific application scenarios of Ball Joint:
1. Daily Commuter Vehicles
Ideal for vehicles used in daily urban or suburban commuting, where frequent start-stop, low-speed turning, and road undulations are common. It maintains stable steering response (tested to reduce steering backlash by 0.2mm) and supports 50,000+ km of daily use—meeting IATF 16949 standards for long-term reliability. Its wear-resistant POM bearing ensures smooth operation even in heavy-traffic, repetitive-use scenarios.
2. Commercial Heavy-Load Vehicles
Suitable for commercial vehicles that carry moderate to heavy loads (e.g., cargo transporters). With a static load capacity of ≥3000N (exceeding ISO 9001’s 2500N standard), it resists deformation under heavy load pressure. The SCM435 alloy steel housing enhances impact resistance by 30%, preventing damage from load-induced stress during long-haul trips.
3. Vehicles in Extreme Climate Zones
Designed for regions with extreme temperatures, from -40℃ (cold northern areas) to 120℃ (hot desert areas). It passed 100-hour high/low-temperature cycle tests without performance degradation. The electrophoretic coating (500-hour salt spray test passed) also protects against corrosion in humid, rainy, or coastal environments—extending component life by 20% vs. uncoated alternatives.
4. Off-Road & Unpaved Road Conditions
Reliable for vehicles frequently driven on gravel, dirt, or off-road trails. It completed 10,000+ fatigue cycles at 15° swing angle (simulating rough terrain jolts) without jamming. The high-strength stud (40Cr steel, HRC 38-42 hardness) resists bending or breaking from uneven road impacts, ensuring consistent suspension and steering function.
5. Professional Repair Shop Replacements
A top choice for auto repair shops due to its 99.8% compatibility rate with target platforms. Its direct-fit design (±0.05mm tolerance) cuts installation time by 40% vs. universal-fit parts, reducing labor costs. Backed by a 24-month warranty and 8-hour technical support, it aligns with repair shops’ demand for efficient, low-risk automotive chassis components.
6. Fleet & Corporate Vehicle Maintenance
Perfect for fleet operators managing large vehicle groups (e.g., logistics fleets). Its 0.3% annual replacement rate (lower than the industry 1.2% average) minimizes maintenance downtime. The consistent quality (6-step factory inspection) ensures uniform performance across all fleet vehicles, simplifying maintenance planning and cost control.
Product Operate Guide
Secure the vehicle on a level surface with a jack and wheel chocks; disconnect the old ball joint.
Align the new ball joint with mounting holes (use a torque wrench to tighten bolts to 55±5 N·m—critical for load-bearing safety).
After installation, test steering range and suspension movement to ensure no jamming; check for loose connections.
