Product Introduction

The AZ9725520277 torque arm is a heavy-duty suspension and axle positioning component used in HOWO 371 and HOWO A7 trucks. It is installed in the axle suspension system to control longitudinal movement of the axle while ensuring correct alignment between the frame, axle, and braking system.

This part is commonly referred to as an axle brake adjustment arm or torque rod. It plays a key role in maintaining front axle positioning stability (前桥定位), ensuring safe handling and consistent braking performance under heavy load conditions.

During operation, the torque arm absorbs torque reaction forces generated from acceleration and braking, preventing axle displacement and maintaining correct suspension geometry. This helps reduce uneven tire wear, improves braking consistency, and enhances driving stability in long-distance and heavy-duty transport applications.

Manufactured from high-strength forged steel with reinforced rubber bushings, this component is designed for harsh working environments such as logistics fleets, mining trucks, and construction vehicles.

Each unit is tested for structural strength, bushing durability, fatigue resistance, and dimensional accuracy before shipment to ensure stable long-term performance.
