ive got the prostreet upper and lowers on my car and when i installed them i noticed the uppers were about a 1/4" shorter than the stock ones. it messed w my pinion angle and now it vibrates. the car is lowered 2" too. didnt know if anyone else has ran into this or atleast noticed that the uppers were shorter? this isnt the first prob. that ive had with UPR!

did you give them a call? i have had 3 or 4 things from them and never had any issues. They actually called me about a month after I got my offroad x-pipe just to ask how it was working out.
Are they adjustable ? All the pro series control arms on there web site are adjustable . If so you have to measure from bolt center to bolt center of the old arms and make the new ones the same . Then you can adjust pinion and tracking from there .
sorry guys i dont have the net at my house right now so it takes a while for me to get back to ya. they are non adjustable, and i didnt call about this issue but i did call about past issues and they gave me 10% off my next order. they seem like a good company and are willing to help. i just didnt know if anyone else had had this prob. wasnt sure if thats just how they come or not.
