Product Advantage
High-Strength Material & Anti-Corrosion Performance
Our drive shaft for Lifan is made of 45# high-carbon steel, which has a tensile strength of up to 600MPa—20% higher than ordinary carbon steel. After professional galvanizing and powder coating, it achieves an anti-corrosion grade of ASTM B117 500-hour salt spray resistance, effectively resisting rust and wear in harsh environments like humid areas or muddy roads. This material selection ensures the drive shaft maintains structural stability for over 80,000 kilometers of use.Precision Machining & Dynamic Balance Optimization
Each drive shaft for Lifan undergoes CNC precision machining with a dimensional tolerance of ±0.02mm, ensuring a perfect fit with Lifan’s original transmission system. We also conduct dynamic balance testing in accordance with ISO 1940-1 standards, controlling the unbalance amount within 5g·mm—this significantly reduces vibration during high-speed rotation, lowering noise and extending the service life of related components.Strict Quality Inspection & Compliance with International Standards
Every batch of our Lifan drive shafts passes 12 rigorous quality inspections, including torque testing (withstanding up to 350N·m without deformation), fatigue testing (100,000 cycles of alternating load), and dimensional inspection. The product fully complies with SAE J2350 and ISO 6413 standards, meeting the quality requirements of global auto parts markets. We have obtained ISO 9001 and IATF 16949 certifications, providing authoritative quality assurance for customers.Customized Design for Lifan’s Power System & Easy Installation
Based on 10+ years of experience in matching Lifan auto parts, our drive shaft is customized according to the parameters of Lifan’s engine and transmission system. The spline connection is optimized to improve power transmission efficiency by 8%, ensuring smooth power output. Additionally, the product adopts a bolt-on design with clear installation marks, allowing technicians to complete replacement within 30 minutes—saving maintenance time and labor costs for customers.Long-Term Warranty & Professional After-Sales Support
We provide a 24-month/60,000-kilometer warranty for our drive shaft for Lifan—far longer than the industry average of 12 months. In case of quality issues within the warranty period, we offer free replacement and technical support. Our after-sales team, consisting of 15+ auto parts engineers with 5+ years of experience, responds to customer inquiries within 24 hours, solving problems related to installation, use, and maintenance in a timely manner.

Product Uses
Here are specific application scenarios of drive shaft:
1.Daily Urban Commuting Scenarios
Ideal for Lifan vehicles used in daily urban travel (80% of urban car owners’ usage scenarios). It maintains stable power transmission during frequent start-stop and low-speed driving, with dynamic balance accuracy ≤5g·mm reducing vibration—avoiding discomfort caused by jitter and ensuring smooth driving even in congested traffic.
2.Complex Road Condition Adaptation
Suitable for areas with muddy, gravel, or hilly roads (common in Southeast Asia, Latin America). Made of 45# high-carbon steel (tensile strength 600MPa) and anti-corrosion coating (500h salt spray resistance), it resists impact from road debris and moisture erosion, ensuring normal operation in harsh environments.
3.Commercial Fleet Operations
Perfect for Lifan commercial vehicles (logistics, passenger transport) with high annual mileage (≥30,000km). Its fatigue life ≥100,000 cycles supports long-term continuous use, reducing replacement frequency. The 24-month warranty also lowers maintenance costs for fleet managers, improving operational efficiency.
4.After-Sales Maintenance Replacement
Essential for auto repair shops undertaking Lifan vehicle maintenance. With bolt-on design and clear marks, installation takes only 30 minutes (saving 50% time vs. generic shafts). It fully matches Lifan’s original transmission parameters, ensuring 1:1 replacement accuracy and avoiding rework due to mismatches.
5.Extreme Temperature Environment Use
Applicable to regions with extreme temperatures (-40℃ ~ +120℃, such as Northern Europe, Middle East). The shaft’s material maintains stable performance without brittleness or deformation, and the spline lubrication system (high-temperature resistant grease) ensures smooth power transfer even in extreme weather.
Product Operate Guide
1. Before installation, check that the shaft body is free of deformation and the spline has no wear. Use a torque wrench to tighten the bolts to the standard of 45-50N·m.
2. Inspect the connection parts every 10,000 kilometers during daily use to prevent loosening.
3. If abnormal vibration occurs (exceeding 65dB), stop the machine immediately for inspection to avoid damaging the transmission system.
4. Abide by the operating temperature range of -40℃~+120℃. If the temperature exceeds this range, take protective measures to ensure a service life of over 80,000 kilometers.
