From what I’ve read unless you’re running a heavy winch or some crazy brush guard they do NOT advise running these on the the higher levels. If you’re looking for more lift I’d say get an actual “lift kit”. These pictures are with 33x12.50 tires they deff don’t look stuffed to me !?
Go with eibach ! You’ll be happy you did. I love the look and drive of mine.
Using the pro truck kit ( springs, shocks, struts )
you do not need new A-arms. I didn’t do anything to the rear and it’s pretty much dead level.
