F->r swap?

Correct me if I am wrong? I have a 4.0 taking the front coils put them on rear and putting v8 coils on the front will yield 3 inches or so. What else is required as far as track bar, lower control, or away bar links? I really don't know was just throwing some things out I think would need changing

I think this lift only applies to the TJ Wrangler. I did this with mine. I use my 4.0 coils in the rear, and a set of front coils from a 98 5.9 ZJ in the front. I got about 3" but there is a lot of difference in the two bodies.

Do not.....argh. bad info.

Check the flaws page for front to rear swap. New shocks will be needed. F150 springs ride like junk. New guys, help the newer guys. Search isn't always the answer.

It's not in the FAQ, unless I missed it?

There are a huge pile of options for this kind of lift (in order of expected lift: XJ I6, XJ UpCountry, ZJ I6, ZJ I6 UpCountry, ZJ V8, ZJ V8 UpCountry.

I6 Cherokee coils netted about 2" and the handling was awful, as the springs were too soft.

I6 ZJ Non-UpCountry give a solid 3", maybe they're good for 3.25". Stock ride and handling, full uptravel in a crossup.

V8 ZJ Non-UpCountry gives about 4". Stock shocks are almost at max extension just sitting still. Don't run them long because the ride is quite rough when the Jeep was empty.

Guesses:
Expect the UpCountry springs to be, say, 1/2" higher than the non-UpCountry versions.

If you only want 2" or so, I bet an I6 XJ spring would get there, if not, then an I6 XJ UpCountry probably would.


Pics include all three options : I6, I6 ZJ, V8 coils (in that order):

Well put. You can search all day but sometimes not find the answer. It gives the new guys the opportunity to share and spread the knowledge that they have gained from this forum and spread it to the newer guys!! Thanks!

With 4.5 RE coils in the front and front V8 up country coils in the rear, I got 3.5 in the rear. I put a 1" puck on top to level it out. That's on a 95 5.2. I wouldn't recommend it though. It was pretty stiff in the back and bounced around. 33's made it a bit softer. I guess you could get even softer shocks in the rear but I wouldn't do that again

All you are saving money on are two rear coils. You still need all of the other things that go with a 3.5" or 4.5" kit. Two coils are hardly worth making your ZJ ride like a dump truck over.

Stock I6 front coils are same coil rate than the stock V8 rear coils are. Placed in the rear they should not ride any stiffer/ harsher than the stock rears, unless you've got stiff shocks.

Have to keep in mind though, there were about ten different coil rates for the ZJ when it was produced, so you'd really have to know which coils to use for which application for proper lift height and ride quality.

i've done I6 coils in the rear from ZJ. gave about 3" or so. i used ZJ v8 coils up front with a 2.5" spacer and it was ok. you need longer length shocks. i have a recipe for this super cheap lift but you gotta earn it you should adress track bars at this stage though. because the front will pull the axle to the drivers side and the rear to the passengers side, so it can feel a little weird over some bumps because the wheels no longer track straight. i would do a front track bar....... or just stay with a 2" BB. either way you can just fit a 31" tire so might as well

3.5 RE springs in front, my V8 fronts in rear, rear ended up being about 2" higher than front, cut almost a full coil, now it sits well and the ride is not bad, but it is definitely stiffer than stock

i can post a pic if you would like

That's the debate I was having is the extra inch worth the $300 or so extra

my ride is far from dump truck like. it actually feels very similar to the front, it moves well through its travel (i put zip ties on the shock shafts to monitor this), now add my 3 kids, wife and full tank. the spring rate seems perfect because of the added leverage from the lift, not looking to change those out, no need.

i have lengthened shocks, clayton dbl shear up front and custom mount with stock bar out back
