I have the Evo Leveling Kit, and when i installed it. I netted 2.5 in the front (stock 4 door, and once it settled 2 1/4). Evo did a great job to were all you need is the front spring and rear spacer to run perfectly fine with everything you already have. When its fully compressed, your bump stops stop the coil right before it goes fully compressed( which is not a good thing) and before your shock bottoms out. And at full flex, it doesnt unseat your coil, or affect your break lines. So if your like me and run light, if you add any spacers to the front. Your going to be 3+ in the front. And that just opens up a different can of worms. Your looking at front lower adjustable control arms to put your drivelines back to normal. if you add new shocks or shock extenstions, you have to modify your break lines. New front drive shaft, new bump stop. So with that, your better off getting an actual 3 in lift kit that sells everything you need like the Evo Enforcer.
