Inner CV Joint Manufacturer & Supplier | Precision Inner Constant Velocity Joints

Reliable Inner CV Joints for Stable Power Transmission

The Inner CV Joint is a vital part of the vehicle's drive axle assembly. Installed between the transmission and the drive shaft, it is responsible for transferring engine torque while compensating for suspension movement and changes in axle length. Unlike the outer joint, the inner CV joint is specifically engineered to allow axial movement, helping maintain smooth power delivery under varying road conditions.

GJF is a professional Inner CV Joint manufacturer with more than 28 years of experience in manufacturing automotive drivetrain components. Our inner constant velocity joints are developed to deliver dependable performance, OE-compatible fitment, and long service life for the global aftermarket.

With an extensive product portfolio covering over 15,000 SKUs and compatibility with 95% of passenger vehicle applications, GJF supplies distributors, wholesalers, importers, and OEM customers in over 100 countries.

Engineered for Smooth Axial Movement

Unlike outer CV joints, inner CV joints are designed to absorb the continuous changes in distance between the transmission and the wheel hub caused by suspension travel.

To achieve this, GJF inner CV joints are manufactured using high-strength 55# alloy steel, precision-machined internal raceways, and carefully heat-treated components that provide excellent wear resistance under high torque conditions.

Every component is produced with strict dimensional control to ensure:

• Smooth plunge movement
• Stable torque transmission
• Reduced drivetrain vibration
• Lower operating noise
• Excellent durability
• Consistent long-term performance

The optimized internal structure helps minimize friction while maintaining reliable lubrication during continuous operation.
