We specialize in universal joints (U-joints), drive shaft, double cardan CV assemblies, and other driveline components such as yokes, spline shafts, and flange yokes, serving both OEM and aftermarket applications.
Our annual production capacity exceeds 12 million sets of universal joints and 100,000 sets of double cardan CV assemblies, supported by fully automatic production lines and in-house heat treatment.
Yes. Our company is certified to ISO 9001 and IATF 16949 quality management systems, ensuring consistent product quality and reliable process control.
The products shown on our website represent only a small part of what we can manufacture. You are welcome to contact us for our latest catalog or samples, or simply share your specific requirements — our engineering and sales teams will recommend the most suitable products for your application.
Our products are compatible with a wide range of vehicles, including passenger cars, light trucks, heavy-duty trucks, construction machinery, agricultural equipment, and special vehicles.
Yes, we do. We provide customized design and manufacturing services based on your drawings, samples, or technical requirements. Whether it’s special dimensions, materials, surface treatment, or packaging, our engineering team can develop tailor-made driveline components to meet your specific needs.
Not only the aftermarket. We also supply to OEM manufacturers, providing high-quality driveline components for both OEM and aftermarket applications.
All of our products are manufactured under the same strict quality management system (IATF 16949 certified) and go through the same inspection and testing procedures.
However, OEM parts are usually produced according to specific technical requirements or validation standards provided by the vehicle manufacturer, while aftermarket products are designed to meet or exceed industry standards and focus more on cost-performance balance.
In both cases, we ensure reliable performance and consistent quality.
We ensure product quality through a strict and comprehensive quality control system. All key processes — from forging, heat treatment, machining, to assembly — are performed in-house under IATF 16949 certified management.
Each batch undergoes dimension inspection, hardness testing, torque and fatigue testing, and other performance evaluations to guarantee that every component meets our standards for strength, durability, and precision.
There are many factors to consider,such as the material of the product, the lubricating oil and grease used, the material of the oil seal, the fit clearance,and the precision of the needle rollers in the same set. If you would like to know detailed information about our products, please contact us by email.
Yes. We can provide test certificates and inspection reports upon request.
Each batch of products can be supplied with material certificates, hardness reports, dimensional inspection data, and performance test results to verify compliance with customer or OEM requirements.
The minimum order quantity (MOQ) varies depending on the product type.
For standard or in-stock items, there is usually no MOQ requirement.
However, for customized or newly developed products, a minimum order quantity may apply due to tooling and setup costs.
Please contact us with your specific product requirements, and we will confirm the most suitable arrangement for you.
In general, the lead time for mass production is around 20–45 days, depending on the product type and order quantity.
For customized or newly developed products, the lead time may vary.

By air — for urgent or small-volume shipments.
By express courier (such as DHL, FedEx, UPS, TNT) — for samples or small packages.
We can also arrange delivery to your designated forwarder or warehouse if needed.
We have extensive export experience and fully understand that sea transportation can take a long time.

Regular maintenance helps ensure stable performance and extend the service life of driveline components.
- For greaseable types: Lubricate the universal joints and slip yokes with the recommended high-quality lithium or molybdenum grease every 5,000–10,000 km (or as specified by your vehicle manufacturer).
- For maintenance-free types: No periodic greasing is required, but regular visual inspection for wear, rust, or seal damage is recommended.
- Always check for vibration, abnormal noise, or looseness in the drive shaft and joints, and replace worn components promptly.
Proper lubrication and timely inspection will greatly reduce wear and prevent premature failure.
We value every customer’s feedback and provide prompt after-sales support.
Once we receive your report or inquiry, our team will respond within 24 hours and begin problem analysis and solution confirmation as soon as possible.
