NO FLEX with my leaf spring lift!!!

So i just bought a 95 wrangler, and it came with a 4" leaf spring lift with pro-comp shocks. this thing rides like crap, and has absolutely no flex! what can i do to fix this. seriously, it doesn't flex even a inch.

If removing the trac and sway bars don't work try loosening the the shackle to spring bolts and retorqueing them to 45 to 50 ftlbs. If the bolts are too tight they will cause the springs to bind in the shackle and the jeep will ride like crap and wont flex.

How new is it? and secondly, are you sure he put the right springs on it? i have heard of people trying to do a cheap lift and taking old springs off of an older truck or something and they end up being too long and dont have any flex. may be something to look into.

No shackles? Ummmm....I'd start there. Your springs can not "spring" if they are fixed at both ends, the need to be able to grow and shrink, hence the shackle. And some pics of the suspension ingenuity would be great also. I would strongly suggest thoroughly checking the rest of the handy of the previous owner as well.

Yea, look in into some revolver shackles and mayb try to track down what leafs it's got. After that some sway bar disconnects and telescoping track bar would really help you

If it has shackles and no track bars then my guess is someone took leaf springs out of a 3/4 ton pick up or something. Unbolt the sway bar and see what it does. You are right on the track bars. They will go from one side if the axle to the opposite side frame rail.

Yes, your trac bars will go from one side of the frame to the other side of the axle, you do not need these on a leaf sprung vehicle. The front sway bar is located under the front of the frame with links going down to either side of the axle near the springs. The sway bar is not needed either, but some people prefer them. I would start with what someone else already mentioned, loosening all of the leaf spring bolts and re-torque them. When you have the nuts loose, you can jump up and down on the Jeep to loosen free it up a little too. Some cheaper suspension kits can be very stiff especially when new. Get the part #'s off of the shocks and make sure that they are also correct, and that they are not mounted upside down. Boomerang shackles may help smooth the ride a little, but make sure your current parts are correct, and correctly installed first.

If it's strictly an off road vehicle. They provide much better road manners that's why I suggested sway bar disconnects and a telescoping track bar so you get the most flex off road and the best possible road manners also might check grease fittings on the bushings if it has them

I have put over 110k miles on with no sway bars or track bars. About 70-80k was with a Superlift 4" kit and 33's, the rest with SOA on 1.5" Rubicon Express springs and 37" MTR's, not any problems. I used it to commute 90 minutes to work each way for several years on the freeway and windy mountain roads. In fact the Superlift was still so stiff even without the TB's and sway, that I could do a 1-2 powershift over the crown of the road, and pull a front tire 4-6" off of the ground and carry it 50'. I have never felt like I wasn't in control of the Jeep because of the suspension mods. It might not be for everyone, but it's far from being dangerous or only for trail only rigs. It's a Jeep, if you need a car that parks for you, or hits your brakes when you get too close to someone, or steers when you fall asleep and cross the line, Mercedes has you covered. Or better yet, stay off of the road, you probably shouldn't be driving anyways.

POS YJ: how much did you get the rubicon express springs for?

I had bad axle wrap and a broken overload spring on my passenger rear so I threw some stock springs on the rear, then found out one of the PO's actually had lift springs on the SOA..

Funny thing was, before i put the stock springs on i accidentally picked up a set of 3.5 inch lift springs from a junkyard.. they were sitting in the tub of a jeep a few jeeps away from the one they were about to pull the springs off of.. so i said hey, save them some time and use these! compared them to the ones they were going to pull which looked compressed but were in full droop.. they seemed to have the same arch, just thicker springs, and 4 leaf instead of 5.. also had full military wrap so i should've known better, found out later after googling a part number on them they were lift springs.. yeah my rear DS vibrated BAD.. i had about 11-12 inches of lift in the rear at that point.

You have shackles!!! That's the thingys that bolt from your leaf springs to the frame. The other side of those leaf springs will not have shackles and again you will have only one pair for the rear also! Now for flexing take off sway bars and check it out, maybe new shocks but maybe she's just stiff!

I'm sorry, I didn't mean to come off rude, and I completely agree with you if you are saying this about a TJ. NEVER EVER remove the track bars on a TJ!

[QUOTE=darkproximity;1202174]POS YJ: how much did you get the rubicon express springs for?

I believe they were about $600 for the set, but RE is going through a bankruptcy right now. I heard that they will be up and running a month or two. Well worth the wait in my opinion. They are firm on the road but flex really well for a leaf spring off road, but I did not mount the fronts in the stock location. Read the next response.

I don't know about the Rough Country kit, but in the past they haven't been the best. For a smoother ride and more flex, you will want to for a leaf that has more leafs in the pack. For example, a 4 leaf 2" lift will be stiffer than a 6 leaf 2" lift. Depending on your fab skills and what you want to get out of the lift, there are some fairly easy things you can do to help the ride. I ditched the stock axles when I went SOA, but I used longer spring perches with multiple pin holes drilled in them, so I was able to move the rear back 1" while leaving the springs in the stock location. On the front, I moved the spring hangers forward 2" with a little longer shackle (2") to make it work. That put my shackles angle at about 30 degrees which I believe greatly improves the ride and flex. I also used the offset spring perches on the front for another inch of wheelbase. You might be able to just drill new holes in your spring perches to extend the wheelbase a little. Right now with the 1.5" springs and 37's, it flexes well (can place a front tire on a 40" object with the other tires still on the ground) and gets minimal rub when at full compression. Before dumping money on a new kit though, I would try to make yours work by re-torquing the leaf and shackle bolts and even greasing the bushings. Try to pull part #'s off of the springs and shocks to make sure you are starting with the correct parts also.
Edit: Pull your track bars and sway bars. With a stiff 4" lift you will not need them. Trust me.

Yea, I knew that lol. I've always owned a tj but I've looked up all kinds of info on yj's too. Hard telling what my @$$ end would do with no track bar, yours just flexes more :jealous: figured id go out on a limb in the yj forum and see if I could b any help. Im actually considering buying a 94 so no hard feelings. And for the op, youve got lots of good information here and one or all of these things can get you more flex. You'll come to like wrangler forum when they fix your jeep for you. They have for me a couple times

You don't wanna find out! That is what holds your axle from shifting side to side. It will fall to one side or the other until your links bind and hold it up. The leafs do it for the YJ though.

Okay, The problem is your Procomp shocks. Remove and replace. Or remove and go test flex in a safe place to make sure there are no other issues.
