I'm looking at fitting a 4 inch lift to my 04 TJ,
I am aware I will need a sye/cv to eliminate any drive shaft vibes. its the control arms that I'm confused about.
I've noticed many kits come with new fixed lower front and rear control arms, but no upper control arms. I've read on here that I will need adjustable upper front and rear control arms to adjust the angle of the drive shaft.
Being pretty mechanically stupid my question is will that work or do I also need adjustable lower front and rear control arms or will the new fixed lower ones supplied with the kit work. Thanks
