Some of you may know but some may not.... I'm now a proud owner of a Black 2008 Jk Rubicon unlimited with a little more than 100,000 high way miles.... I've been looking at lifts for a while now and I'm set on a four inch lift, but I'm deciding on weather I should spend about 1,200-300 on a short arm complete kit or to save up 1,600-900 for a rough country complete long arm.... I know I'd get more flex with a long arm but that's just about all I know. I figure if I'm going to spend the money I want to only spend it once. I will be running 37's with 4:10's and stiffeners if that's a factor with long or short arms or type of lift.... Lastly I'm pretty sure controll arm spacers arnt too good on the trails do to collapsing but is that really true?
