Thought I would support one of our vendors so I just bought one, let's see how it does

 

What, if any, is the difference between the two sway bars? I'm thinking about getting one for my HHR.

 

From what I see its the diameter of the bar itself that is the difference. The Sus Tech bar is larger diameter than the Prog Tech's. they both appear to be bent in the same shape and mount the same way as well. I have the Prog Tech and am happy with the results. I have the rear leveled as well and the combo seems to work really well.

 

The TTR one is around 66% stronger than the Progress.

The TTR Rear sway bar is the largest on the market today :)
