The air spring upper bracket is one of those parts you never think about until a bang from the rear suspension tells you it has cracked. This bracket (DZ95259440320) bolts to the top of the air bag and ties it into the frame, so once it fails the bag starts walking and the truck leans to one side. Ours is cast from Q345 steel and coated against rust, so it takes the load and the road salt without argument. Where it fits SHACMAN Delong trucks with rear air suspension Top mount
