Drag link is a link for transmitting rotary motion between cranks on two parallel but slightly offset shafts, such as the rod connecting the lever of the steering gear to the steering arm an automobile. It is also a tube or rod used as connection between the pitman arm and steering knuckle. The factory drag link is bowed to clear the lower spring bucket and sway the bar mount. The new Currie arm is also bent to give additional clearance in the area because they found the stock rod would hit the axle when the suspension is crossed.

It is normally used on cars and light trucks. The term drag link is commonly used in automotive technology for the link in a four bar steering linkage. The most common drag link is the Pro Comp drag link. This linkage converts the rotation of a steering arm to a center link and to the tie rod link which will pivot the wheels to be steered.
