The Alltrux ATX21690 Drag Link replaces OEM 85128559 and is designed as a service replacement for heavy-duty truck steering systems. It connects the steering gearbox to the steering arm, transmitting steering input to the front axle to support precise steering response and consistent vehicle control in fleet and vocational environments.

Drag links play a critical role in steering system operation by maintaining proper alignment and transferring motion between steering components. As original drag links wear, develop joint play, or suffer damage from road stress and vibration, steering looseness, uneven tire wear, and reduced handling precision can occur. Replacing worn drag links helps restore proper steering geometry, improve vehicle control, and reduce unplanned service events.
