I have a 93 Jeep YJ and want to put a lift on it. i was thinking of going with a spring over lift but i recently heard that they have a scary amount of body roll going into corners. Being that i drive this Jeep on the road 90% of the time i would like anyones opinion on if this is true or not. Thanks in advance.  

Unless you are going to drive it like a sports car I wouldn't worry about it.  There are just some things that you have to live with when you lift something.  

Would you happen to know if it is worse on a spring over because of the softer stock springs a opposed to the harder archer springs on a spring under? If not hanks for your help anyways.  

The stock springs flex more due to being strait.  The lift springs that are arched more tend to be stiffer due to the mechanical disadvantage of the angle of the spring in relation to the shackles.  This lessens body roll during normal driving.  But once you compress the springs they will actually get softer due to the shackle pushing the spring laterally.  This is how jeeps with 6" lifts still have flex but have a rough ride going down the road.  I personally would go ahead with the spring over kit and just live with the body roll then add springs later if I didn't like it.  A little body roll naver hurt anyone.  Just be conservitave going arround corners and you will be ok.

Thanks for the help. its appreciated  

I have a spring over on my modified 57 CJ5 but I only drive on the road to get to trails. If I were going to drive on the road as much as you say that you do, I would go with a 4in. spring under lift, a 1-1/2 or 2 inch body lift and trim the fenders. 35 inch tires can be used with this combination depending on how much fender triming you do. I have seen this done and it works well.    

the other possible lift i was thinking of was a bds 6 inch system, and i've driven a jeep with it. it performed well on the road but then i was worried it wouldnt flex well on the trail. thanks for the advice.

I forgot. YJ's have anti sway bars from the factory. If you leave them hooked up on the street with the spring over the body roll will be kept to a minimum. Get disconnect's for the front and unhook it when on the trail. Leave the back one hooked up all of the time. A Currie front anti sway bar or adjustable shocks are another option.   

Expect that you will need to build some trac bars for the rear if you go with a spring over.  

Yeah i figured i'd need to build a trac bar for the rear  

thanks for the help  

go to readers rides and check out my 95 yj. if you're gonna do a spring over, i would advise a shackle reversal. rubicon express makes a good kit that moves the front axle forward about 1 1/2". a track bar is needed but skyjacker offers a good single ladder bar with a shakle that still allows axle travel. the factory sway bars are not needed. i have about 10" of lift and have been driving mine for about 3 years like it is and have no problems. a crossover high steer kit really helps as well  

I would also do a spring over conversion with track bars and shackle reversal however I would buy a cheap set of toyota torsion bars and build disconnectable sway bars that would be relatively simple to install and would control the sway problem in turns at road speeds.  this in turn controls even the factory sway problem that weak factory sway bars create.  I have even seen a decent set of swaybars nearly eliminate the wheelhop from my daily driver neon- drove like a pile of **** until the sway bar was replaced with a heavier one.  The way it did that is it made both wheelscancell each others hopping action out because of moving in opposite directions at the same rate of speed (well known problem with Neons).  

i dont know how a neon handles...but i do know how a yj handles. mods to the sway bar are not needed. you either run it and be stiff, or take them off and flex. when you do a spring over your spring pads switch sides, and it bolts right back up as it did in stock form... if you wanna run them. if you're just gonna run stock springs with no add-a-leafs and be a black top warrior, run them. if you're gonna use after market springs and want your rig to be able to climb a tree or keep all four on the ground out on a trail,  scrap the sway bars
