Hey, question on lifting my jeep! I recently bought a 99 TJ with a 2.5" lift kit already installed. I want to raise it to a 4". Question is this; Do i need to buy a complete 4" lift kit or can I just modify what I have? Obviously I'll need bigger springs, But do I need to swap out the control arms, Pitman arm, ect. Basically, what is the cheapest route to go? The shocks are Bilsteen that are fairly new, so I'd like to keep them if possible.
