I'm wondering whats the most amount of lift you can do to a Rubicon without having to install longer control arms

 

We have a 4" spring lift,stock arms

 

What else besides springs and shocks did you have to change?

 

You would definitely need longer brake lines or brackets with 4". Also, adjustable track bars and/or brackets should really be installed. And, without adjustable lower front control arms (or relocation brackets) I can almost guarantee you will have a very "flighty" driving Jeep.

I personally would stop at around 2 1/2", and still plan on adjustable lower control arms and trck bar/brackets.

 

I'm currently running a 2 1/2 spacer lift with a drop down bracket for the rear sway bar. I have recently purchased 3 1/2 inch lifted springs and 3 inch longer shocks, so I want to make sure I have all the parts I require before I start ripping it apart to run my new 35's
