I had to look twice to realize the perspective of the photo and where that bar is mounted. As its been noted, this arrangement does not have any movement for the bar. But that is the design, it isn't intended to move. It is not like typical sway bars that pivot toward the front and swing. This type pretty much anchors the two trailing arms (radius rods) together rather solidly. Perhaps is was designed with a more forgiving bar to account for that. There have been vehicles with the same design from the factory. It works, but the suspension was intended for it. No idea what the long term effects are with it on the X, however it actually appears to have survived so far. Any idea how long it has been there? Any evidence of bushing damage, rod damage, etc? It can offer a greater amount of control over the usual style, but there might be trade offs for that. Probably better for a track car. One benefit is improved ground clearance over the more traditional type sway bar. As for the type of clamps it has, that's the same basic arrangement as most American vehicles used for the rear leaf springs for decades; a U-bolt and bracket mounted directly onto the components. Perhaps it's not as bad as first impressions may indicate? Curious who it was manufactured by.
