4\" lift all done i started putting my 4" lift on my 84 k5 yesturday about 9 am. and was done by 7pm. everything went smooth . i dont have any viberation problems yet , but will probably drop the t-case anyways. i do still need to get the brake lines for the front before i do any wheeling. i like it and so does my son. he helped for a little while ,but at nine years old, his interests got weak after a couple hours. thanks guys for all your posts that had to do with advise.
