Dunno if I can give you installation tips because my friend, works at a local Dodge service station, installed them for me. He installed both front and rear. If your gonna install it yourself, I've heard the rear one is the pain in the ass. I do can tell you this, after he installed them, I popped the hood and rev my engine and the thing JUST STAYS THERE. It would not rock back and forth. Also, the car feels A LOT more torquier. The vibrations weren't as bad though!!!! Sorry I couldn't be of more help.
