What is needed for a basic 4 inch lift ?

[MudRunnerTD]

In my opinion. if your going to go 3 inch you your better of going 4inch as your going to be technically illegal and 1 inch over the max allowed is not a lot at all. plus you will find that you will still need an adjustable drag link, adjustable panhard rods plus the rear upper and lower control arms. If you want to do it properly. Or, just buy a decent two kit. 3 inch just seems a waste of time.

I have a 3" lift under my GU and its a great height. Enough room to run 35s without too many issues. Doesnt stand out. Enough lift to get the drop boxes in as a 2" lift your stuck with bushes only. You dont need to change rear trailing arms at all on a 3". I would change out the lowers for HD standard length though which i have done. You can get away with standard panards to if you want.

4" then absolutely do need adjustable panards front and rear and Upper trailing arm adjustment added to the list.
