Rear Axle Main Reducer Assembly OE 2402010-KE02KB for Dongfeng GX & KX Heavy Trucks

This genuine rear axle main reducer assembly with OE number 2402010-KE02KB is factory original rear drive axle core component exclusively matched for Dongfeng GX and KX heavy-duty tractors. It reduces drive shaft rotational speed, amplifies output torque and distributes power to left and right rear wheels via differential mechanism. The housing adopts high-strength cast ductile iron with excellent shock resistance. Precision machined spiral bevel gear pair undergoes strict heat treatment to achieve high surface hardness and wear resistance. Optimized gear meshing design lowers operating noise and vibration under heavy load. Standard flange mounting hole layout fully matches Dongfeng GX/KX rear axle housing for direct bolt-on replacement. This main reducer strictly passes DFCV OEM long-duration heavy-load fatigue test, gear meshing noise test and oil tightness durability test. Authorized third-party driveline component inspection verifies mounting dimension, gear ratio and spline specification fully consistent with factory original assemblies, widely used as full replacement spare parts for abnormal noise, gear wear and leakage failed reducers on Dongfeng GX & KX long-haul fleets.

PRODUCT DESCRIPTION

Built-in differential gear assembly internal component close-up rear axle main reducer OE 2402010-KE02KB

Precision Hypoid Gear, Ductile Iron Housing, Low Vibration & Oil Tight Structure

This OE 2402010-KE02KB rear axle main reducer adopts high-precision hypoid spiral bevel gear set manufactured via strict carburizing quenching process. Smooth gear meshing effectively suppresses transmission vibration and running noise under full load. The integral ductile iron carrier housing boasts strong impact resistance, suitable for heavy-load transportation on rough roads. Multiple composite sealing structures are equipped at all rotating joints to prevent gear oil leakage. Internal differential assembly uses reinforced bearings to improve load bearing performance. Flange hole layout strictly follows original Dongfeng GX & KX rear axle size, realizing direct whole-unit replacement without additional machining. Optimized lubrication channel design ensures sufficient gear oil circulation to avoid dry friction and premature gear ablation.

Poor Gear Precision Causes Loud Noise, Weak Housing Easy Deformation, Simple Seal Leaks Oil

Heavy truck driveline maintenance technicians often encounter many failures caused by inferior aftermarket main reducers: low-precision gears produce severe roar noise during driving; ordinary cast iron housing deforms under heavy load leading to gear offset; single-layer simple sealing causes continuous gear oil leakage, accelerating gear wear. This genuine DFCV OEM rear axle main reducer completely eliminates these hidden risks: high precision gear set ensures quiet operation; ductile iron housing resists deformation; multi-ring sealing prevents oil leakage, lowering rear axle overhaul frequency for Dongfeng GX & KX logistics fleets.

DFCV OEM GX/KX Rear Axle Standard, Multi-Round Load & Sealing Lab Testing

As core power transmission spare part of Dongfeng GX & KX heavy truck rear drive axle system, this rear axle main reducer fully complies with Dongfeng Commercial Vehicle official heavy-duty driveline component production quality standards. Every finished reducer completes three mandatory durability laboratory tests: thousands of hours continuous heavy-load fatigue test, gear meshing noise detection test, long-cycle static and dynamic oil tightness test, maintaining stable transmission performance under plateau climbing, high-speed long haul and bumpy mountain road conditions. Anti-counterfeit QR code and OEM part number marking are printed on original wooden packaging for genuine product traceability. All flange mounting dimension, gear tooth parameter and spline specification strictly follow factory engineering drawings, zero assembly mismatch after replacement for all Dongfeng GX and KX heavy truck models.
