GJF Auto Transmission Parts CV Axle CV Joint CV Boot

Complete Driveline Solutions from One Supplier

The driveline system plays an important role in transferring engine power to the wheels. A complete solution may involve several connected components, including the CV Axle, CV Joint, and CV Boot.

For automotive wholesalers, distributors, retailers, and repair businesses, sourcing these products from different suppliers can increase purchasing time and make product matching more complicated.

GJF Auto Parts focuses on automotive transmission and driveline components, providing CV Axle, CV Joint, and CV Boot solutions from one specialized supplier.

With a broad application range and a focus on OE fit, reliable power transmission, durable protection, and consistent quality, GJF helps customers simplify their sourcing process and build a more complete aftermarket product range.

One supplier. Three key driveline solutions. More efficient sourcing.

Specialized in Automotive Transmission Parts

GJF focuses on driveline-related automotive parts rather than offering an unrelated product catalogue.

This specialization allows customers to source several connected products through one supply chain, including:

• CV Axle / Drive Shaft
• Inner CV Joint
• Outer CV Joint
• CV Joint Bearing
• CV Joint Boot
• Intermediate Shaft
• Related driveline components

The product range is designed for different passenger vehicle applications and supports a broad selection of Japanese, Korean, and other vehicle models.

For customers who regularly purchase transmission and driveline parts, this focused product portfolio can make supplier management easier while providing more options for different vehicle applications.

CV Axle for Reliable Power Transmission

The CV Axle connects the transmission or differential to the driven wheel and transfers torque while accommodating changes in suspension movement and operating angles.

GJF CV Axles are developed with attention to strength, dimensional accuracy, and stable power transmission.

Key features include:

High-Strength CF53 Steel

CF53 steel is used for applicable drive shaft components to provide a strong foundation for repeated torque transmission and mechanical loading.

≥500,000-Cycle Fatigue-Tested Performance

Selected drive shaft components undergo fatigue testing of 500,000 cycles or more, supporting durability evaluation under repeated loading conditions.

High-Precision Automated Machining

Automated machining helps maintain dimensional consistency across important shaft and connection areas.

Stable Torque Transmission

The design supports efficient power transfer while helping reduce unnecessary vibration and noise during operation.

Together, these features help create a CV Axle solution suitable for demanding aftermarket applications.

CV Joint for Smooth Power Transfer

The CV Joint allows torque to be transmitted while accommodating changes in the operating angle of the driveline.

Depending on the application, GJF provides different CV Joint configurations, including inner and outer joint solutions.

Important manufacturing considerations include:

• Accurate spline and thread dimensions
• Heat-treated and wear-resistant steel
• Precision-machined components
• Reliable internal lubrication
• Application-specific fitment

GJF uses one-step spline and thread processing for applicable components to support dimensional accuracy and consistent assembly.

The combination of precision components and suitable lubrication helps maintain smooth torque transfer and reduce unnecessary friction and wear.

CV Boot for Joint Protection

The CV Boot is the protective barrier around the CV Joint.

Its main function is to help retain grease inside the joint while preventing dirt, water, dust, and other contaminants from reaching the internal components.

GJF CV Boots use imported neoprene rubber for applicable applications.

The material is designed to provide flexibility, tensile strength, and sealing performance during repeated movement.

-40°C to 120°C Temperature Resistance

GJF CV Boots are designed for an approximate operating temperature range of -40°C to 120°C, helping maintain flexibility and sealing performance under changing environmental conditions.

Seals Grease and Blocks Contamination

A properly sealed CV Boot helps:

• Keep grease inside the CV Joint
• Block dirt and dust
• Reduce moisture exposure
• Protect internal components
• Reduce contamination-related wear

High Tensile Strength and Airtightness

The boot needs to flex repeatedly as the suspension and driveline move.

High tensile strength and reliable airtightness help maintain the protective seal during operation and reduce the risk of grease leakage.

Designed as a Complete Driveline Solution

One advantage of sourcing related products from the same specialist supplier is easier product coordination.

The CV Axle, CV Joint, and CV Boot work together as parts of the same driveline system.

GJF can therefore support customers across different replacement requirements:

CV Axle
Complete power transmission solution between the drivetrain and wheels.

CV Joint
Transfers torque while allowing the required operating angle.

CV Boot
Protects the CV Joint by retaining grease and blocking contamination.

This product combination gives distributors and wholesalers a more focused way to develop their driveline product range.

OE Fit and Application Matching

Correct fitment is essential for driveline replacement parts.

GJF products are developed with attention to OE application requirements, including dimensions, spline configuration, thread specifications, joint size, boot dimensions, and mounting interfaces.

Customers can provide:

• OE number
• Vehicle make and model
• Production year
• Engine information
• VIN, where required

GJF can use this information to help identify the appropriate product application.

This application-focused approach is especially useful for aftermarket businesses handling multiple vehicle models.

Quality Focus from Component to Finished Product

For B2B customers, stable quality between different batches is an important consideration.

GJF focuses on key production stages, including material selection, precision machining, component assembly, lubrication, boot sealing, and final inspection.

This approach is intended to support:

• Consistent product dimensions
• Stable assembly quality
• Reliable sealing
• Smooth operation
• Reduced installation problems
• Lower risk of avoidable returns

The goal is to provide products that are not only suitable for the required application, but also consistent enough for long-term aftermarket supply.

More Than One Product — One Sourcing Solution

For customers purchasing automotive transmission parts, supplier specialization can simplify communication and purchasing.

Instead of managing separate suppliers for CV Axles, CV Joints, and CV Boots, GJF provides a focused driveline product portfolio under one brand.

This can help customers:

• Consolidate purchasing
• Expand their product range
• Simplify supplier communication
• Match more vehicle applications
• Reduce sourcing time
• Develop a more complete driveline catalogue

GJF's approach is based on combining product specialization, broad application support, stable quality, and aftermarket sourcing efficiency.
