I dont know, I guess maybe it isnt limiting flex, but that it just looks small since I have 31's on it. My rear spring is inverted. I would have done the same to the other side, but I couldnt find a spot where I could pull up like this on the pass side. You see my lower shock mounts are as high as I could get them without limit travel too much. Plus the Teraflex bar helps. It also doesnt look as flexy since the passenger side wasnt able to go down, I could only pull up on this to see how high I could get the driver side to flex up since that is the side my traction bar is on and the side that would be the most restricted.

I really hate these pics underneath BTW, it all has nice paint and looks almost new. That mud is irresistible though.

FWIW: I have very similar springs, my antiwrap bar is in the same spot and I've wheeled without a bar (and broken driveshafts) and I've wheeled with.

I've tried different springs, shackles, bars, 31s,33s,35s and 37s and even different bars.

Everything certainly has a trade off. I have to keep in mind that my "responsiveness" is a little high when I'm climbing obstacles on my driver side rear. This has resulted in (almost) unnecessary roll overs.

With 37s and crap springs and no anti-wrap bar I've busted a driveshaft on a highway on ramp. We could all give up and switch to 3 links and coilovers but how fun is that??

I don't like rolling in ***** situations and I don't like breaking driveshafts on on-ramps.

I think you're on the right track. Good job not getting distracted as the old timers flame each other...

Yes my shackle moves. Greased not too long ago, and not overtightened.

Yeah I am not getting distracted by these guys arguing with each other.

Can not tell are you running boomerangs in the rear?
I run a high misalighnmet hiem with spacers at the front part of the traction bar.
Seems to help.

My bar looks almost the same as yours. Bushings on axle and and pivot has a heim, except I run mine on the passenger side. I was curious about flex when I first got going so I tried flexing the rear. Did it once, measured then disconnected the heim end and did again. Got about the same measurements surprisingly. Running RE 1.5" springs.

Also out of curiosity, what angle is your pinion at compared to your output yoke? Looks a lot lower than the 1-3 degrees recommended.

Nope, angle is fine. Pic is while it is flexed so it looks weird. I have no vibes at all. It is 3 degrees on the dot. I mounted mine on the driver side since the 8.8 is offset a couple inches to the passenger side. That way I kept it as far towards center as possible.

Overkill,

My old 2.5L YJ was set up pretty much identical to yours but I was running 35's. I had about the same amount of flex in the rear. I beat the piss out of that jeep. Moab, the Hammers at JV and alot of stuff here in AZ, that jeep could do just about anything. Seems like your front is flexing pretty good so I would not worry so much about the flex in the rear. I would bet that eventually you may want larger tires and regear to 4.88's. When that happens you will want that traction bar. If you want better offroad performance put a cheap locker in the front diff and leave the rear limited alone. You will be amazed at what a front locker will do offroad.

Yeah, I got a front locker in there. I installed it three weeks ago. I am only going to 33's so I am torn on a regear. Not sure if it is worth it since I will be swapping the engine within a year. 4.10 is nice with bigger motor

If your swapping the engine and going 33's you will need that traction bar.

Looks like the angle of the shackle might be hitting the crossmember at full flex. If it were me I would try drilling a new hole further away from the crossmember so there was no chance of contact between the two.
