Made in Longmont CO. I've seen quite a variation in the quality of the aluminum the body is made out of. I have a set on my IH B140 that has extremely soft, almost "pot metal" aluminum for the body. However, this is a 1.25 ton truck that has been worked extremely hard and the Dualmatics are still there and operational. They have a failure mode which involves operator error. They allow you to engage/disengage the cylinders independently. Thus they can be locked in with less than all of the cylinders in lock position, thereby weakening the hub.
