What is drag link?

A drag link is a type of steering linkage that connects the steering wheel to the front wheels of a vehicle. It is typically used in vehicles with a recirculating ball steering system, such as trucks, SUVs, and some older cars.

The drag link is a solid metal rod or bar that connects the pitman arm (attached to the steering box) to the steering arm (attached to the steering knuckle). When the steering wheel is turned, the drag link transmits this motion to the front wheels, allowing the driver to steer the vehicle.

The drag link plays a crucial role in the steering system of a vehicle, as it must be able to withstand the forces and pressures exerted on it while turning the wheels. It is important that the drag link is properly lubricated and maintained to ensure smooth and responsive steering.

In some vehicles, the drag link may also incorporate a ball joint or tie rod end, which allows for flexibility and movement in the steering system. If the drag link becomes worn or damaged, it can lead to poor steering, alignment issues, and unsafe driving conditions.

Overall, the drag link is a key component of the steering system that helps control the direction of a vehicle and should be inspected regularly as part of routine maintenance.
