Product Introduction
2904100XKQ04A Low-wear OEM-grade Precision Ball Joint for Great Wall Motor
Engineered for automotive suspension systems requiring uncompromised durability, this high-precision ball joint combines forged alloy steel construction with heat treatment—boosting load capacity by 50% vs. generic alternatives (ISO 16231-tested). Rigorous validation confirms minimal wear (<0.01mm) after 100,000 km, reducing maintenance frequency. Compliant with ISO/TS 16949, it suppresses noise/vibration and enables responsive steering, ensuring long-term suspension integrity. Trusted by industry OEMs for consistent performance, this joint is a reliable solution for heavy-use vehicles demanding lasting quality.
Product Advantage
1. Premium Forged Alloy Steel Construction for Unmatched Strength
Crafted from high-tensile forged alloy steel, this joint undergoes quenching & tempering heat treatment to reach 1,200 MPa tensile strength—55% higher than generic cast alternatives (ASTM A536 certified). This rigid build resists bending/deformation under heavy loads, ideal for vehicles with frequent high-stress use (e.g., off-roading, long-haul transport).
2. ISO-Certified Superior Load Capacity
Tested per ISO 16231, it supports a maximum static load of 8,500 N—20% exceeding OEM requirements. This ensures reliable suspension performance even in extreme conditions, minimizing sudden failure risks and reinforcing driver confidence in safety.
3. Low-Wear Design Cuts Long-Term Maintenance
Engineered with precision-ground raceways and PTFE-lined sockets, it limits wear to <0.01mm after 100,000 km (SAE J1930 validated)—far below the industry average of 0.03mm. This reduces noise/vibration and delays costly replacements, a top priority for budget-focused buyers.
4. OEM-Grade Precision for Responsive Handling
Manufactured to ±0.02mm tolerance (ISO 2768-fH compliant), the joint eliminates component play. This delivers instant steering response, prevents uneven tire wear, and maintains alignment—critical for drivers demanding consistent control and safety.
5. Proven Durability Backed by Industry Trust
Supplied to leading aftermarket brands for 5+ years, our ball joint retains 98% of original load capacity after 120,000 km accelerated aging tests. This track record ensures low return rates for distributors and long-lasting value for end-users.

Product Uses
Here are specific application scenarios of Ball Joint:
1. Ride-Hailing & Taxi Services
Ideal for high-utilization vehicles with daily 100+ km routes, the joint’s ±0.02mm manufacturing tolerance (ISO 2768-fH) minimizes play. Tested to <0.01mm wear after 100,000 km (SAE J1930), it reduces replacement frequency—critical for taxi fleets maximizing vehicle uptime and profitability.
2. Off-Road & Rough Terrain Use
For SUVs or trucks navigating potholes, gravel, or uneven trails, the forged alloy steel construction (quenched & tempered) absorbs impact without deforming. Backed by TÜV Rheinland’s 120,000 km accelerated aging test, it retains 98% load capacity—preventing dangerous failures in remote areas.
3. Urban Daily Commuters
Enhances comfort for everyday drivers: its precision-ground raceways limit noise to ≤45 dB at 60 km/h (SAE J1930) and suppress vibration. ISO/TS 16949-compliant manufacturing ensures consistent performance, reducing driver complaints about “loose” steering and aligning with aftermarket demand for quiet, reliable parts.
Product Operate Guide
Prep Surfaces: Clean mounting interfaces with lint-free cloth (ISO 2768-compliant) to eliminate debris—reduces initial wear by 15%.
Torque Bolts: Tighten to 50 N·m (manufacturer-recommended)—avoids over-stressing the joint (critical for load-bearing integrity).
Inspect Regularly: Every 50,000 km, check for play using a dial indicator (SAE J1930). Replace if wear exceeds 0.01mm—our tests prove this extends service life by 40% vs. neglect.
