The good news is that it will move your front end out 2 inches, but the bad news is your going to have to stretch the front of the frame that extra 2 in the front to make it where the spring will actually fit. Now, that's with a YJ spring, if you use something longer, thats a wholenother can o worms. I wouldn't stretch it out if you plan on driving it alot on the road simply because you do have to mess with a fuel cell of some sort and I dont like any sort of fuel inside the passenger compartment with me unless its a trail only rig.

edit, I did forget to measure the length of the brackets down from the frame to see if there was any difference.
Yea I figured maybe to far forward from the numbers I had and basing off that frame bracket for control arm. So if I just figured if I grind off that control arm bracket, and mount my own back the few inches I need that would work right. So basically make center pin right where the axle is now an weld brackets to frame. Not to say as far forward as I can, or as a Yj is but perhaps that is where it would line up. Weld fron eye similar to a yj on front most of frame and then weld in the rear where I need.

Sacrificing a tad bit of ground clearance but if I do a 1" case drop it wouldn't be much more or equal to that so why not. make sense at all?

I think I would cut the factory junk off and weld my own on too. I can get you the exact measurments off a YJ frame if needed. How big are you gonna go? I wouldn't worry about dropping the case just yet until you get the axles in it and see what its going to look like. You can always do what I said and put a bigger joint that will allow for more travel and strength.....wonder if they make a 1410 yoke for that case?

Yea that sounds like what I am gonna do if you see the brackets and shackle mounts I posted earlier it can't be much more cut and paste. As for measurements I'll be doing in garage with one SOA rig I asked about before, and another bone stock so I figured all the numbers I needed. As forheight I figured short stock length shackles. 2.5" OME front and rear leaf springs for a YJ. SOA that's it. No more needed and just want to run 35's so that should do it fine. Assuming numbers match up as an SOA would effect a Yj not sure if it will add or lack an inch on a TJ. I would avoid case drop if I can for sure. I'll see if I can get that adaptor for the rubi case. Worse case I am not at all against the loss from a case drop to know no vibrations and u joints blowin out.

Overall what's your input on this setup cause I'm pretty pumped to have this rig

The only thing I am remotely worried about is if the springs are going to set it level once its done....basically, are you going to be able to get them proportionate to each other versus the ground. I don't know enough about TJ frames to say one set of brackets will be higher or lower than a YJ causing rake or sag.

Other than that I say let her rip; you know I am the king of off the beaten path hehe

Haha. Well yea that is one thing I did think about. Is if the frame sits level with mounts to make springs sit proper for it to cycle through suspension. I'm gonna do a ton of measuring,,,,, hoping this one email I'm getting from a local who likes my jeep has what seems to be a rare 90k original mile YJ 91 he may trade and car loan for the rest. Again love a YJ but never seem to find one that isn't like a pos inside falling apart or torn up. Could take the others advise and with 10k or so in cash get crazy with some serious cleaning and fabbing.

alot to read here, so I just kinda skimmed.


My strong suggestion is to figure your axle placement, do some rough measurements and call up alcan spring. They can build you a set of springs for your specific wants and needs and make it so you do not need to compromise. With whatever yj or whatever other springs you have to deal with whatever center pin location that may not be ideal for approach or departure angles. Your losing out on that by ditching leafs. Keep it low. Keep your mounts close to frame and you will be set up.

Btw leafs are NOT a cure all for death wobble. I know plenty of people with wobble on leafs. It's all about lateral movement , toe, caster, and sloppy bushings etc. Just know that although leafs are predictable and easy, you lose some basic tbings that links give. I would factor in an antiwrap bar for the rear because leafs love to wrap.

I have a good amount of experience with leafs, on full size trucks and they so have their placement. But boy did I get sick of bashing them into rocks.

Interesting I've never driven a leaf sprung vehicle that has had DW.

74 j10

Try a 74 J10 with bad steering dampener. Hits 55 and it will take the steering wheel out of your hand. Ask me how I know that????

That sucks....are you sure thats all it is? I run alot of my stuff without a steering stabilizer. In every case I have seen, they just mask the problem enough were its tollerable.

J10 death wobble

Had it on 2 different FSJ vehicles. Both cases would start at 55 mph and you better get it down fast. Replaced the steering stabilizer and totally cured the problem. Stabilizer was positively bad, no resitance at all.

They both had over 100,000 miles so there could have been some play in the suspension but it was solid in the steering otherwise.

I have met other FSJ's in that time period that I would see start to wobble the same way and see them brake and then pick up again.

Kev had that problem in his CJ and it was the sector shaft. I havent messed with too many FSJ's so I cant say.
