Product Introduction

The WG7121325271 differential assembly is a heavy-duty inter axle differential component designed for SINOTRUK HOWO MAT16 axle systems used in heavy-duty truck applications. The differential is responsible for distributing torque between drive axles while allowing wheel speed differences during vehicle turning and uneven road operation, improving drivetrain stability and traction performance. 

This differential assembly features a 31-tooth precision gear structure manufactured from high-strength alloy steel materials with advanced heat treatment processing to ensure excellent wear resistance, high load-bearing capability, and stable torque transmission under continuous heavy-duty operating conditions.

The product is widely used in heavy-duty logistics trucks, mining dump trucks, construction transport vehicles, and long-haul transportation applications where stable differential performance is critical for axle durability and drivetrain efficiency. Precision ground gear teeth help reduce transmission noise and improve gear meshing stability during operation. Genuine HOWO differential systems are designed to improve traction efficiency and heavy-load reliability under demanding road environments.

According to supplier specifications, WG7121325271 is commonly identified as a MAT16 inter axle differential assembly used in SINOTRUK heavy-duty axle systems.

The differential assembly is engineered according to OEM specifications for direct-fit installation and reliable compatibility with original HOWO drivetrain systems. Each unit undergoes gear hardness testing, dimensional inspection, gear meshing testing, and durability verification before shipment to ensure OEM-level quality and long service life.
