There are two of the Heidts clones out there. There is one that is better then Heidts in my opinion. That one is a forged steel spindle, Heidt's are cast steel. Then there is a cast version and it's bad, actually saw some break on a car, they can be identified by a dark color, kind of a dark greenish color. The good clones can be recognized by the forging parting line as opposed to a thin cast parting line, some of you may not have an idea what I'm talking about others know what a forge parting line looks like, same as a forged crankshaft. The parting line runs around the perimeter of the body not down the center. Unfortunately you may not know which one until after you buy them.
