I'm at about 3.5 lift and just got adjustable uca and lca, can I center my axle (35s) with these...ie stretch a little? Also any tips for installing would be helpful.
As long as you have good thread depth you should be able to. It also makes a difference if you have drop brackets or not. you will be able to get more stretch with the arms more horizontal.
Just remember to check clearances and watch you track bar and diff.
