This OEM-quality replacement drive shaft is engineered to restore your vehicle's peak performance and driving safety. Manufactured from high-strength alloy steel and subjected to rigorous heat treatment, it boasts a superior tensile strength of over 1000 MPa and exceptional fatigue resistance for guaranteed longevity.
Precision-machined to exact original specifications, the assembly ensures perfect fitment and optimal balance. It undergoes advanced dynamic balancing testing, achieving a tolerance under 15 g/cm to eliminate vibrations and ensure buttery-smooth power transmission from the transmission to the wheels.
Tough, zinc-phosphate plating provides superior corrosion resistance, protecting against rust and wear in harsh conditions. Each unit is 100% tested to meet strict quality standards, offering a reliable, direct-fit solution that delivers unmatched durability and value for money.
Crafted from high-grade 42CrMo alloy steel and subjected to a precise quenching and tempering heat treatment, our drive shaft achieves an exceptional surface hardness of HRC 58-62 and a core tensile strength exceeding 1200 MPa. This durable Lifan drive shaft is engineered to withstand high torsional and impact loads, significantly outperforming standard components and ensuring a dramatically extended service life even under the most demanding driving conditions.
Vibration reduction is critical for drivetrain health. Each unit undergoes advanced computer-controlled dynamic balancing, achieving an industry-leading tolerance of under 15 g·cm. This meticulous process for our precision-balanced Lifan drive shaft guarantees buttery-smooth rotation, eliminates unwanted vibrations, and prevents premature wear on adjacent components like bearings and transmissions, ensuring a quiet and comfortable ride.
To guarantee longevity in all climates, we employ a multi-stage surface protection system. A robust zinc-phosphate coating is applied, followed by a sealant of high-performance anti-rust oil. This combination provides superior defense, successfully passing over 120 hours of neutral salt spray testing (ASTM B117) without failure. This corrosion-resistant drive shaft is built to resist rust and degradation from rain, humidity, and road salts.
We utilize original equipment specifications and state-of-the-art CNC machining to ensure every spline, journal, and flange is manufactured to exact tolerances. Our OEM-quality Lifan drive shaft is a direct replacement, guaranteeing a perfect fit and seamless integration with your vehicle's drivetrain. This eliminates installation hassles and ensures optimal power transmission, restoring your vehicle to its original performance standards.
Every drive shaft is 100% tested under a stringent quality control protocol that includes dimensional checks, torque tests, and material verification. Our reliable aftermarket drive shaft is produced in an ISO 9001:2015 certified facility, providing you with the utmost confidence in product consistency, reliability, and performance. We stand behind the quality of our components with full traceability.

Here are specific application scenarios of drive shaft:
This drive shaft serves as a precise, direct replacement for original parts that have reached the end of their service life. Common indicators for replacement include audible clicking or knocking sounds during sharp turns, excessive vibration during acceleration, or visible damage to the CV joint boots leading to grease leakage and joint contamination. Our OEM-quality unit is engineered to seamlessly restore the vehicle's drivetrain integrity, ensuring smooth and reliable power transmission.
This component is the definitive solution for resolving drivetrain vibrations, particularly those felt through the steering wheel or floorpan during acceleration. Often caused by an imbalanced or damaged shaft, these vibrations can accelerate wear on other components. Our drive shaft, balanced to a precise tolerance of under 15 g·cm, eliminates these vibrations, providing a smooth ride and protecting expensive adjacent parts like wheel bearings and transmission differentials.
The integrated CV joints are protected by rubber boots that can crack or tear over time due to heat, age, or road debris. This allows grease to escape and contaminants to enter, leading to rapid joint wear and failure. Our complete axle assembly comes with new, durable boots pre-greased and pre-assembled, making it the most efficient and reliable solution for this very common repair scenario, saving significant labor time.
Following events like a significant pothole impact, collision, or any incident that compromises the drivetrain, a bent or otherwise damaged drive shaft is a frequent result. Our high-strength unit, manufactured from 42CrMo alloy steel with a tensile strength exceeding 1100 MPa, provides a robust and reliable replacement to restore the vehicle to its pre-incident performance and safety standards.
For vehicles with high mileage, proactively replacing the drive shaft is a strategic maintenance decision. It prevents unexpected and costly roadside failures and avoids further damage to the transmission and wheel hub assemblies. Installing a new, reliable unit ensures continued drivetrain performance and is a recommended practice for ensuring overall vehicle safety and reliability.
For optimal performance and safety, please follow these guidelines. Prior to installation, always visually inspect the new part for any transit damage. Ensure the vehicle is securely lifted and supported on jack stands. Use a torque wrench to tighten all flange bolts and axle nuts to the manufacturer's specified torque setting (typically between 120-180 N·m for axle nuts) to prevent under or over-tightening. After installation, perform a short test drive at low speed in a safe area to check for unusual vibrations or noises before normal operation. For complex issues, we recommend consulting a professional mechanic.
