Drag links and idlers are found in the steering system of Class 7 and Class 8 trucks, and are responsible for ensuring accurate and responsive steering. The drag link transmits the driver’s steering input to the wheels by connecting the steering gear to the steering arms, while the idler arms provide support and reduce friction in the linkage. Designed for heavy-duty use, these components must withstand the forces generated by large trucks and challenging road conditions. Maintaining the proper function of drag links and idlers is essential for ensuring safe, smooth handling and prolonging the life of the steering system.
