Leaf Spring Shackles - Semi Truck

How Do Semi Truck Leaf Spring Shackles Work?

A semi truck leaf spring shackle is a steel bracket which one end mounts to the end of a leaf spring and the other to a hanger or to the frame of a vehicle. The shackle pivots as the vehicle goes over uneven surfaces in the road which allows the spring to lengthen and flex. This movement absorbs road shock and provides a smooth ride.
