Steering Drag Linkage Arm QT65EQ0-3001007 Foton

Product Introduction

This robust linkage arm is a core structural component of the steering system, designed to transmit the rotational force from the steering gear’s pitman shaft to the drag link, enabling precise steering of the front wheels.

• Structure & Material:

• Material: High-strength ductile iron, precision-forged and heat-treated for maximum rigidity, impact resistance, and fatigue strength.

• Design: A one-piece forged arm with two precision-machined mounting holes: one for the splined pitman shaft and another for the drag link’s ball joint.

• Finish: A durable black oxide coating provides corrosion resistance against road debris, water, and salt.

  • Performance:

• Transmits steering forces efficiently, ensuring responsive and precise vehicle handling even under heavy loads and uneven road conditions.

• The robust forged design minimizes flex, maintaining accurate steering geometry and preventing premature wear on other steering components.

  • Durability: The heavy-duty ductile iron construction withstands the high torque, vibration, and impact of heavy truck operation, ensuring long service life.

  • Compatibility: Direct OE replacement, fully matching the spline count, hole spacing, and mounting specifications of the original drag linkage arm.

Core Function

1. Force Transmission: Converts the rotational output of the steering gear into linear movement of the drag link.

2. Steering Linkage: Acts as the primary connection between the steering gear and the front steering knuckles.

3. Precision Control: Maintains accurate steering geometry for stable handling and optimal tire wear.
