Product Introduction

The AZ9725520278 torque arm is a heavy-duty chassis suspension and axle positioning component used in HOWO 6×4 tractor truck applications. It is installed between the axle and chassis frame to control longitudinal axle movement and maintain correct alignment of the suspension and braking system.

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

During vehicle operation, the torque arm absorbs torque reaction forces generated during acceleration and braking. It prevents axle displacement, maintains correct suspension geometry, and helps reduce tire wear and steering instability, especially in long-distance and heavy-load operation scenarios.

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

Each unit is tested for dimensional accuracy, fatigue resistance, and bushing durability before shipment to ensure stable and long service life performance.
