I put a set of springs under my 7 today. They were under it when I got it and I took them out because it was a Bubba job. I thought they were 6" but they only lifted it about 4 1/2". Tomorrow I'm going to cut down a CV drive shaft I have, The one in it now has a bad vibration, but I expected that. The rear seems to sit up more than the front. I hope they settle down some.
