Going jeeping! Should I dissconnect Sway Bar?

Going jeeping at the end of the week! I have stock suspension (2" body lift)(33" tires), would it be wise to disconnect that for maximum flex? It is also my DD, so I don't want to make it unsafe on a normal basis.

That's not much lift for 33s. You probably don't have much room for flex. If you disconnect it, you could smash your fenders.

In my experience, if you have 33s, you probably have enough traction to articulate to the point of breaking the bolts out of track bars and such. Ive never broke a sway bar or any part of one but I broke bolts and mounts off trac bars on both my YJ's before removing them for good. One was stock suspension and one has 3.5 inches of lift. 31x10.50s on both jeeps with open diffs... If your just trail riding you should be fine but if your gonna see what its limits are I would yank the trac bars off. Just my opinion of course...

Yes, I would take track bars off. They're kind of pointless on a YJ anyway.

I agree, but I'd still take it off with the trac bars because you'd have a softer ride off road. I live where all dirt roads are washed out and hardpan so I know rough rides. Just don't try to go flex that suspension with 33's. I don't even know how you managed 33's with 2". You must have a shackle lift to or something....

I ran 33s on 2-2.5" for a week, until I got tube fenders. I rubbed going over everything, even pulling into my driveway. That was with the sway bar connected, too. If I went off road with that setup, I'd leave the sway bar on. You won't mess up your fenders/flares by stuffing your tires into them.

So here's what I've gathered:

Pros:
Smoother ride.
Slightly more flex.

Cons:
I risk destroying my fenders.

I think I might pull them anyways, and just be careful. I couldn't tell you anything more than there's a 2" body lift. The PO did that setup. The springs are flat of course, but the tires have a good 2-3" before the top of the fender. Just enough to play it safely.

Thanks guys!

well if you can't tell if you have a shackle lift, the stock shackles are 4" from eye to eye. If you have anything bigger, then you have shackle lift . Best of luck on your trip

"Slightly more flex" is an understatement. With a sway bar, there is _no_ flex in the front suspension. Without it, there is. Period.

Track bars are, in my opinion, useless. Others will tell you otherwise. Best course there is to research it on your own, and make your own choice. i ran with no track bars for almost the entire life of my 92 YJ. Never saw negative effects, but maybe I just wasnt looking for them.

BTW, trim those fenders, either by replacing them with aftermarket (more expensive, possibly not road-legal in your state) or do the TJ flare swap, you'll gain quite a bit of clearance for those 33's. i ran 33's on my 3.5" superlift for years with stock flares, and i rubbed. Swapped to TJ flares (and trimmed accordingly) and i never contacted the fenders again.

Now that I'm not on the mobile app and can see avatar pics, it looks like you have about a 1" shackle lift. You should have enough room to flex a bit and not hit your front fenders, but you will hit the flares, so be careful.

One of my favorite low center of gravity setups was when I had 33s, 2-2.5" lift, and tube fenders. You should look into tube fenders or aftermarket flares. You could gain a lot more clearance and not have to worry about rubbing/bending stuff with your tires.

I would recommend you to disconnect the front sway bar links from the front axle and remove the track bars from the axles. Hang them all up on the frame out of the way. Then go for a ride. See how you like it. If you are not happy, attach front sway bar links and go for another ride.

To figure out if your tires are too big, shocks too short, or bump stops too short, go articulate the Jeep. Put into 4wd low, idle up driver's side tire till you loose traction. Park it, get out and look. The front bump stop should be on the axle, the rear bump stops on the leaf spring (front of axle) and on axle. Tires shouldn't be on the fenders or flares. The shocks should be showing their rod.

I gained 3-4 inches of flex when I pulled my sway and track bars. With 3.5 inches of lift my stock bump stops just happened to be perfect for 31x10.50s after I cut an inch of metal off the fenders and moved the flares up. I still caught the plastic flare when set up like this if I was trying to flex but not on the trail in general... Now Im on 35s with the same set up and its ridiculous. Rubs at every little twist...

I think you have about 3 inches of lift on yours. If you get twisted up you could end up damaging tires or fenders or removing a flare by accident.. "Could" being the key word there...

Some things you need to pay attention to:

-Brake lines. With a 1" shackle lift on mine, I was at the limit with my brake lines, they were nearly taut at full flex.

-Track Bars. They bind up the YJ's suspension and counter-act everything the suspension is designed to do. Recommendation is to remove them, you will not experience any side effects without them on (unless you have damaged suspension/steering components in the first place, in which case the Track Bar will act like a bandaid).

-YJ leafs are nearly flat from the factory.

33's will rub on everything, I would personally toss a pair of 30" tires on there for now until you can lift the Jeep.

Here is my 89 (the YJ not the Cherokar):



1" shackles, stock leafs, no track bars, swaybar disconnected, 29" tires. That is about as much flex as you will get out of it, and my 29" tires are rubbing. The brake lines are tight, any tighter and they might have snapped.

For a tad more brake line length Ive heard of people unbolting the brake line support thingy (technical term) where it changes from hard line to hose... There has to be something already done for the body lift. Well at least there should be...

I have hard line and a flaring tool that I extended all my brake lines with by like 6", I also got the braided steel lines and have never had braking issues

you can always trim the fenders and raise the flares. there is a lot of room to be had. i trimmed my fenders up and back and moved my flares flush to the top and back as far as i trimmed. i ran no sway bar and no trac bars with only a 3" body lift and never rubbed.
that is just the body lift

When i finally ditched the 3.5" and went SOA on stock springs, i moved the brake hard-lines in the front to beneath the frame. Mounted somewhere out of the way of the suspension, i put mine next to the bumpstop.

Gets you about 4" of extra slack in the brake lines.

Now, be careful, too much slack, and they rub your tires, and thats BAD. I ended up with longer lines from Crown Automotive, and the relocated hardline. I had to tie the brake lines out of the way so they wouldnt rub on the tires.



You can see the orange bungie cord around the brake line in the background here. Apparently I didnt take a good picture of it.
