Product Introduction

The AZ9725529271 torque arm is a heavy-duty rear axle positioning component used in HOWO 8×4 dump truck applications. It is installed in the suspension system between the axle and chassis frame to control longitudinal movement of the rear axle under heavy load conditions.

This component is also referred to as a rear thrust rod or axle brake adjustment arm. It plays a critical role in maintaining rear axle positioning stability, ensuring proper axle alignment and stable braking performance during high-load transportation.

During vehicle operation, the torque arm absorbs driving and braking reaction forces from the axle, preventing unwanted forward and backward axle displacement. This helps maintain correct suspension geometry, improves braking consistency, reduces tire wear, and enhances overall vehicle stability—especially in construction, mining, and heavy cargo transport environments.

Manufactured from high-strength forged steel with heavy-duty rubber bushings, this part is engineered for extreme working conditions and long service life under continuous impact and vibration loads.

Each unit undergoes strict factory testing, including dimensional inspection, fatigue resistance testing, and bushing durability verification before shipment.
