Product Introduction

This heavy-duty rear axle reducer assembly integrates the differential and final drive gearset, engineered to handle the extreme torque and loads of commercial vehicle operations.

• Structure & Material: The housing is made from high-strength cast iron, while the gears and differential components are forged from alloy steel and heat-treated for maximum hardness and wear resistance.

• Performance: It delivers a fixed gear ratio to multiply torque from the transmission, enabling the vehicle to carry heavy loads and climb steep grades. The differential allows the drive wheels to rotate at different speeds during turns, improving handling and tire life.

• Durability: The robust construction and hardened components withstand high torque, shock loads, and continuous operation, ensuring long service life even under harsh conditions.

• Compatibility: Direct OE replacement, fully matching the mounting points and gear ratio specifications of the target vehicle’s rear axle.

Core Function

1. Torque Multiplication & Speed Reduction: Redrives the transmission output to provide higher torque at the wheels, adapting engine power to vehicle speed and load requirements.

2. Power Distribution: The differential splits torque between the left and right drive wheels, allowing them to turn at different speeds during cornering.

3. Load Handling: Transmits the full weight of the vehicle and its cargo through the axle, maintaining stability and traction.

Rear Axle Reducer Assembly 2402010KE02GA for Dongfeng DFM Trucks

When your Dongfeng heavy-duty truck demands reliable torque multiplication and smooth power transfer to the drive wheels, the Rear Axle Reducer Assembly 2402010KE02GA delivers exactly that. Engineered as a direct-fit replacement for Dongfeng (DFM) rear axle systems, this final drive assembly ensures your fleet stays on the road — hauling more, breaking down less. At Mettlead, we supply this genuine-spec component straight from the factory floor, so you get OEM-level performance without the inflated price tag.

Key Functions and Benefits of the 2402010KE02GA Rear Axle Reducer Assembly

The rear axle reducer assembly — also known as the main reducer or final drive assembly — sits at the heart of your truck’s drivetrain. Here’s what it does and why it matters for your operations:

• Speed Reduction and Torque Amplification: This assembly takes high-speed, low-torque input from the driveshaft and converts it into low-speed, high-torque output. As a result, your Dongfeng truck gains the pulling power it needs for heavy loads and steep grades.
• Power Direction Change: The hypoid gear set redirects rotational force by 90 degrees — from the longitudinal driveshaft to the lateral half-shafts — enabling the rear wheels to receive power efficiently.
• Integrated Differential Mechanism: Built into this assembly, the differential allows the left and right drive wheels to rotate at different speeds during cornering. Consequently, tire wear is reduced and handling stability improves significantly.
• Direct OEM Replacement: Part number 2402010KE02GA ensures a bolt-on fit with no modifications required. This means less downtime during installation and guaranteed compatibility with your Dongfeng platform.
• Durable Construction: Manufactured with heat-treated alloy steel gears and precision-machined housings, this reducer assembly withstands the punishing demands of long-haul and heavy-duty applications.

Application Scenarios: Which Vehicles Does This Fit?

The Rear Axle Reducer Assembly 2402010KE02GA is specifically designed for the Dongfeng (DFM) heavy truck platform. More specifically, it is compatible with the following series:

• Dongfeng Tianlong (Kinland): Long-haul tractor units and heavy-duty cargo trucks that require maximum torque delivery over extended distances.
• Dongfeng Tianjin (Kinrun): Medium-to-heavy-duty trucks used in regional distribution, construction logistics, and municipal services.
• Other DFM Heavy-Duty Models: Any Dongfeng truck platform specifying OEM part number 2402010KE02GA for the rear axle final drive unit.

Whether your trucks are hauling construction materials across rough terrain or delivering goods on intercity highways, this reducer assembly provides the torque multiplication and directional power transfer that keeps your fleet productive.

Frequently Asked Questions (FAQ)

What exactly does the rear axle reducer assembly do in a Dongfeng truck?

The rear axle reducer assembly — often called the main reducer or final drive — performs three critical jobs simultaneously. First, it reduces the rotational speed coming from the driveshaft while multiplying torque. Second, it changes the direction of power flow by 90 degrees to drive the rear wheels. Third, its integrated differential allows the left and right wheels to spin at different speeds during turns. Without a properly functioning reducer assembly, your truck simply cannot transfer engine power to the ground effectively.

How do I confirm that part number 2402010KE02GA fits my specific Dongfeng truck?

The most reliable method is to check the original part number stamped on your existing rear axle reducer assembly or reference your truck’s parts catalog. The 2402010KE02GA is designed for Dongfeng Tianlong and Tianjin series heavy trucks. However, if you’re unsure, simply send us your truck model, year, and VIN number, and our technical team will verify compatibility before shipment.

What are the signs that my rear axle reducer assembly needs replacement?

Several symptoms indicate a failing main reducer. These include unusual whining or howling noises from the rear axle — especially under load — excessive vibration through the drivetrain, oil leaks from the reducer housing, and metal particles found in the rear axle lubricant. If left unaddressed, a damaged reducer assembly can lead to complete rear axle failure, which is far more costly to repair.

Is this a genuine OEM part or an aftermarket replacement?

This is an OEM-specification aftermarket replacement manufactured to match the original equipment’s dimensions, material grades, and performance standards. It is produced under strict quality control protocols, ensuring it delivers the same reliability and fitment as the factory-installed unit — but at a significantly more competitive price point.

What gear oil specification does this reducer assembly require?

Typically, Dongfeng rear axle reducer assemblies require GL-5 grade heavy-duty gear oil with a viscosity of 85W-90 or 80W-90, depending on your operating climate. Always refer to your specific truck’s maintenance manual for the recommended lubricant specification and fill capacity. Proper lubrication is essential for maximizing the service life of the hypoid gear set.

Can I order this reducer assembly with custom branding or packaging?

Absolutely. Mettlead offers white-label and custom packaging services for all our components, including the 2402010KE02GA rear axle reducer assembly.
