I have the four link concept down from racing but the Jeep adds some new questions since I am not replacing some stuff.
I doing 3.5" RE standard kit, but I also purchased all new adjustable short arms.
I can do any of the following and kind of wondering where to go.
Option 1(my pick)
Lift everything adjust wheelbase pinion angles and everything back to where it is just be higher. Front driveshaft concerns me here a tad bit but not sure, have not seen how far it can go.
Option 2(
)
Pull front in to lessen whellbase and give more clearance.
Option 3(
)
Pull back in
Option 4(![Thinking](https://www.jk-forum.com/forums/images/smilies/thinking.gif)
)
Do a little of each and get some more.
Truly with a digital level/dial thing that has a name but I cant think of it, tape measure, and some plumb bobs I can do any of the above and hit damn close if not exact to where I am at right now or where I want to go.
Opinions???????????

If you contact the manafacture you got the control arms from and tell them the lift height, they will be able to tell you the length the arms need to be set at to achieve the correct angles.

Maybe I am not understanding something here, but:
You are lifting so that you can run bigger tires, correct?
And when you lift, the axles are pulled in, right? (the front axle moves backward, the rear axle moves forward)
So if you have both sets of arms for each end, you can move the axles back to where they started.
Sounds like you are over-complicating things...

I have the measurements they provided, that is not the point truly. I know what they say to adjust them to, but given I have the ability to do so and keep all angles correct, will the 2-3 of wheelbase help that much? It will change the center and what it can clear but is it evern worrth the effort? As far as 4-link goes, if I can get something to take off and clear a 1/4 in 9 seconds, I am pretty sure the JK alignment will be simple. Truly to go exactly back with simple tools you would plumbob the center of the axle prior to removing anything or lifting. Add everything and recenter and put pinion angles where they need to be by way of laser or levels. This is simple compaired to pulling a wheel forward to launch inline vs drifting off the center or jerking hard to one side. Given they did provide measurements, they are only going to get you so close and those are for the general install and to get you to an alignment shop. That is not something I bother with most of the time. I normally save my 50-75 bucks for
and align the thing myself. With the Jeep lift you are actually not changing toe so that makes it even easier. Both sides just have to be the same. Where you put them is your choice. Maybe I just overcomplicated something I was thinking about and will just do it each way and measure breakover on the center to find out if it is worth it.
