Ok, so ive searched and found some info, but some people swear this wont work, and some say its a simple deal. Im puttin in a FF60 and am gonna run 37s when all said and done. ive trimmed the front of my rear fenders all i can, but have a ton of chopping room in the rear. I have a bastard pack of RE leaves, at about 6.5" more or less, as well as a 1.5 shackle. when i flip this, i can expect about 3" of added wheelbase, right? this is where the info gets foggy...
how much does an arched spring effect the WB change?
how much will it fawk with the pinion angle (not a big deal, since ill be setting up the perches, but still...)
how will the shackle effect the leaves, performance wise and ride height wise?

with 8+ inches of lift, do i still need to rework the gas tank? can i get by without major mods, or do i need to MOVE it? can i just bumpstop the fawk out of it so i CANT hit it? btw, i was planning on a shock hoop anyway, cause thats obviously needed...

anything else im forgetting?

im using stock chevy 1/2 ton rear springs on my XJ. it has a 8+ lift as well and the rear axle was shoved back 2-2.5" and thats with the stock shackles. all it is, is the spring is 2in. longer (52") than stock and the centerpin moves your axle back some. id try that and see how you like it. you will notice the legth if you hold them next to your cherokee springs.

Search of AZFJ (I think)....he's got a friend with an orage XJ with the rear springs flipped around.

I'm pretty sure its more than 3 inches in length difference....but I may be wrong.

You may also want to search for TrevorXJ he moved his axle backwards, but not by flipping the springs.

is it a site or on here

i think he runs custom alcans but not at all 100% sure on that.

This is my friends XJ with flipped springs..I think it moved the rear axle like 5 inches back!!..Lots of work invloved if you want to keep your stock gas tank location!..some shackle work is due also!

yea, I think I remember him having alcans that were not flipped around....I just remember him moving the axle back and it being a pretty sweet jeep.

I run XJ's on the rear of my CJ (flipped). It will net you 5-5.5" , if you wanna get really tricky orbit eyes(note front bushing twist) will fit in the large end :)

very interesting. How much problem does axle wrap give you mcgyver?

So just stock chebby 1500 springs, do are you saying i need to get 8" lift packs? i dont need more than 3" really so i think i like that idea, better than all the others, just cause alcans are pricey and theres tons of 1500s in the JY's. i didnt want this to turn into a huge project with a fuel cell and all this other chit, so this might be the best bet. i just need to figure out if its a stocker pack or a lifted one?

i've heard that you'll get really bad axle wrap if you flip your springs...they're offset with the short side in front to reduce axle wrap :)

no im using stock chevy blazer rears and they give ya like 3in lift. take them and place them next to yours and youll see how far back it goes. im not sure bout using the JY's ive never heard of them. but let me know how it looks.

Paul

JY = junkyard...i just meant we have a ton of 1500s in them around here. thats the option im leaning towards the most, only issue is that i need about 6+" of lift if im replacing my packs. i guess i could get a k5blazer or something and then bastardize the pack with some of the leaves i have laying around? Alcans or custom springs arent in the cards, so its either flip-flop mine and deal with axlewrap, or the chevy springs and some mix-n-match action.
i dont wanna fab up too much in the way of spring hangers and new shackle designs, this was supposed to be a quick swap :rolleyes: ... someone mentioned these to me.... http://www.offroaddesign.com/catalog/Zero%20Rates.htm i know its cheating, but :flipoff2: any opinions?

i would mix packs with waggys or something else that flexes good. make sure if you do get the chevy springs that there the 52" ones. or mix them with some that have lift, just use the main leave and mix with others that way you get your lift and the axle back the way you want it. and they basically bolt in the stock place no extra lengthening or whatever.

Axle wrap is almost nill thanks to the bam-bar :)

Nice. Problems with it unloading during climbs?

Thanks,doesn't seem to be a problem no.

..nope.. :D

AZFJ ya have the rest of that pic.

AZFJ ya have the rest of that pic.

..I'll look..but I dont think so..He was climbing a little waterfall..pinned the tire under a ledge and about f'd up the T/C output or rear shaft..his rear shackle was almost vertical( and it's a big bitch )..he has only had minimal problems with axle wrap and his rear springs are realy soft..I'll look for a better pic of his !..this is all I have

I want to know a bit more about that Bam Bar. Isn't that essentialy a single bar set-up? I've seen them before but never with the "shackle" bar extending all the way to the xfer case. I have limited room and, if it works, that would work perfect for my set-up. -Thanks

Just noticed the post.

Let you know what I did. At first I was going to use RE XJ leafs then flip them to get my desired wheelbase. The problem came in when I started mocking up the rear axle. You see, the XJ leafs centerpin is drilled 3" foward of center of leafs. So when you flipped them they where 3" behind now, this made adj. pinion angle a b**ch. Since now when the spings set on the perches the spring was already arching up a good bit. To deal with this problem I even tried to flip all the leafs around except for the main leaf. Of course I had to redrill some of the holes, but this did not help as the main leaf did not want to adjust to the new arch. After trying a couple other little things I decide to order custom Alcan leafs, made exactly how I wanted.

They are made 52" long, have an extra 175 lbs a weight, and the center pin is drilled 1" behind center. This neated me about an additional 4 to 5 inches of wheelbase.

As it sits now I am at 108" on 38's

Hey trevor....any updates on the rig?

Check out Jeepaholics forums for info on the bambar. They also have a writeup on their site.

We flipped the rear springs on my friends XJ last year. The most work was rebuilding the wheelwells. Removed stock gas tank and went with interior fuel cell. A traction bar is absolutly required. Gained 6" of wheelbase. Had to modify shackles for bigger spring eyes. Also had to install shims for pinion angle.

All in all it's a very good mod, and makes it much easier to run bigger tires with less lift. He's running 38.5 SXs with 5.5 lift. We also built the front suspension, so his wheelbase is at 111".

the bambar is an awesome choice in my opinion. i tried the traditional ladder style with shackle & it worked also but the bambar a vast improvement as far as lack of binding goes in my application. there are a few writeups online about the bambar (google) :) you wont be dissapointed.
