thanks any more tips would be greatly appreciated. hey another thing I'm worried about is how long the uppers and lowers should be on a 3 1/2 lift.front and back.im reading fir that height stock length is a good starting point until I get to the alignment shop.

yea that was another thing I was needing and the video didn't explain length.

Just reading this. Trigonometry. The length of one side stays constant. Control arm mount to point above axel on frame. The hight from axel to frame increased by 3.5 in
Old
x2 + y^2 = ca^2
New
x^2 + (y+3.5)^2 = (ca+n)^2

CA = old control arm length.
N is how much longer than stock.
This should be close
