Product Introduction
1401261180 OE-Level High-Durability High-performance Inner Ball Joint for Geely KingKong
The 1401261180 inner ball joint is a critical steering and suspension component, designed to connect control arms and steering knuckles for smooth, precise vehicle handling. Backed by 15+ years of OE-level manufacturing experience, it meets ISO/TS 16949 standards and undergoes 3-stage quality checks (dimensional, material, durability) to ensure reliability.
With a 100,000+ km service life and 5000+ N load-bearing capacity, it resists wear, corrosion, and extreme temperatures (-40°C to 120°C). Its precision-machined housing and high-grade bearing grease guarantee consistent performance, reducing steering play and enhancing driving safety. Fully interchangeable with original parts for easy installation.
Product Advantage
1. OE-Level Quality & Authoritative Certifications
This 1401261180 inner ball joint strictly adheres to global auto parts standards, holding ISO/TS 16949 and SGS certifications—critical for meeting the quality requirements of international markets. Our production line follows OE manufacturing processes, with a product qualification rate of 99.8% after batch testing. This ensures the part’s performance is consistent with original components, eliminating concerns about fitment or reliability.
2. High-Durability Materials & Extended Service Life
To address the wear challenges of durable inner ball joint applications, we use high-strength SCM435 alloy for the joint’s housing and a chrome-plated bearing pin. These materials resist corrosion and impact, with a tested service life of 120,000+ km—20% longer than standard inner ball joints. The part also withstands extreme temperatures from -40°C to 150°C, making it suitable for diverse climatic conditions, from cold northern regions to hot tropical areas.
3. Precision Engineering for Stable Steering Performance
As a high-performance inner ball joint, it undergoes CNC precision machining with a dimensional tolerance of only ±0.02mm. This tight precision minimizes steering play (≤0.5mm) and ensures smooth connection between control arms and steering knuckles. We also inject high-temperature resistant lithium-based grease into the joint, which maintains lubrication for 80,000+ km without additional maintenance. This directly enhances driving stability and reduces the risk of steering failure.
4. Rigorous Multi-Stage Quality Testing
Every 1401261180 inner ball joint goes through 4 stages of testing before leaving the factory: 1) Dimensional inspection via 3D scanning; 2) Load-bearing test (withstanding 5,500N without deformation); 3) 480-hour salt spray test for corrosion resistance; 4) Dynamic fatigue test (1 million cycles of simulated road vibration). This rigorous process ensures each part meets our quality standards, with a customer complaint rate of less than 0.3% over the past 5 years.
5. Easy Installation & Wide Compatibility
Designed for hassle-free replacement, the 1401261180 inner ball joint is fully interchangeable with original parts—no modifications to the vehicle’s steering system are needed. It fits standard installation tools, reducing repair time by 30% compared to non-standard alternatives. Additionally, we provide a 2-year/40,000 km warranty for this part, giving customers long-term peace of mind and supporting your after-sales service commitments.

Product Uses
Here are specific application scenarios of Ball Joint:
1. Daily Urban Commuting
Ideal for vehicles used in daily city driving, where frequent steering (e.g., traffic jams, turns) demands stable performance. Its ≤0.5mm steering play ensures precise control, while the 120,000+ km service life aligns with average urban vehicle usage cycles. The lithium-based grease also avoids frequent maintenance, reducing downtime for daily commuters.
2. Extreme Climate Regions
Suitable for areas with harsh weather—from -40°C cold northern zones to 150°C hot deserts. It passes 480-hour salt spray tests (ASTM B117), resisting rust in rainy or coastal areas with high salt content. The high-strength alloy housing also withstands thermal expansion/contraction, preventing cracks in extreme temperatures.
3. Aftermarket Repair & Replacement
As a direct OE replacement inner ball joint, it’s widely used in auto repair shops. Its 1:1 OE fitment eliminates modification needs, cutting installation time by 30% compared to non-standard parts. Backed by a 2-year/40,000 km warranty, it’s a reliable choice for repair businesses aiming to reduce post-service complaints.
4. Commercial Fleet Operations
Ideal for commercial fleets (e.g., delivery vans, service vehicles) where low downtime is critical. Its 0.3% annual failure rate (based on 5-year customer data) minimizes unexpected repairs. The durable design also aligns with fleet maintenance schedules, reducing long-term replacement costs for fleet managers.
Product Operate Guide
We recommend professional technicians perform installation, following ISO auto repair standards to ensure safety. First, prepare standard socket wrenches and torque tools. Check the joint for no damage (e.g., seal cracks) before use.
Install by aligning with control arms/steering knuckles (direct OE fit), then fasten bolts to 25-30 N·m torque (tested for optimal stability). After installation, test steering play—ensure it’s ≤0.5mm. No extra lubrication needed; the pre-filled grease works for 80,000+ km.
