I just installed these. I can't really say much about them yet since I haven't really gotten to drive on them much. One of my end link nuts cross threaded so I am waiting on some new ones I bought from a forum member. So maybe in the future I could offer some better experience on them after I get things sorted out. Mainly I wanted to post up a photo of before and after so people could get a reference of the height change they offer.
The before picture was taken a couple months before. I just happened to have that photo.
