What is a Torque Rod?
A torque rod can also be called a radius rod, radius arm, torque arm, or dog bone. Torque rods are suspension links that are meant to limit the movement of the axles without limiting suspension articulation. Torque arm suspensions are very common on medium and heavy-duty trucks and trailers. Torque rods can be longitudinal (running forward and aft), or they can be transverse (running side to side). On truck drive axles the torque rods will keep the axle centered in the frame and control the driveline angles by managing the torque that is running through the driveline and the axles. On trailers, the torque arms will keep the axles centered and aligned to prevent dog-tracking and tire wear. Torque rods are often overlooked, but they play an important role in the longevity of suspension components and tires. They work by resisting change along the length of the assembly. The forces generated by driving down the road will pull or push on the torque rods, and they are designed to bear these stresses instead of other suspension components. Bushings in each end dampen the stresses and allow the torque rod to be mounted to the vehicle.
The List of available Torque Rod Assembly are as given below.
