This sealed torque rod is 17.75 inches long from the center of each mounting hole, with a 1-1/4 inch rod diameter and 5/8-inch mounting holes. It is used primarily on Mack truck suspensions to prevent axle wrap and excessive clunking, and is typically replaced when the bushings wear out or the rod bends.
