A drag link flip kit could help with steering control.

And if the ride is too stiff you could always change up the shocks to softer ones

The body lift won't affect handling. If you're getting driveline vibes you could need a new front driveshaft. 4" could potentially hurt the front shaft on a 2 door

X2^^^^ + bring your tire pressure down to 25-28psi. Due to changing control arms, Recheck complete 4wheel alignment to make sure diffs are square in the frame and pinion/caster angles. Also ensure that toe is set properly.

With a 4" lift and then a 2" body lift, Im surprised you can maintain control at all honestly. You definitely want a drag link flip kit. Being that you own a 2 door, I don't know why you're running essentially 6" of lift when I know guys running 40s running 3-4", but thats besides the point. Some of your modifications unfortunately ruined the geometry of your jeep, so you will never have "good" road manners with them installed. Just my opinion.

A 4" lift using stock control arm mounts is going to not handle great. Do to the control arm angles. I'm guessing your issues are over responsive handling and darting when one wheel hits a dip. What happens is that when the suspension compresses on one side or the other, the control arm arc causes the axle to move forward. The greater the lift, the greater the forward push during compression. This causes the axle to angle from left to right, which causes a steering affect. The only solution is a long arm kit. You can limit this affect with a stiffer sway bar to prevent some body roll when cornering.

You have alignment #'s. Are the angles set right. I agree with these guys but it's not like you don't have a more complete lift. I am going to go out on a limb here and say shocks, especially with 20" wheels. I have E rated tires with Rancho shocks and the ride is firm but not harsh.

Agree with this. If you have a 4" lift, why do you need an extra 2" body lift? 4" is plenty to clear 35's.

Remove the body lift, better shocks (with reservoir), drag link kit (like the Synergy kit with relocation).

Lower the jeep, buy some good shocks. Do your homework next time.

Or, buy a 4.5" AEV kit from the beginning. :-)

There is absolutely no need for a 4.5" lift for 35s. The 2 door is already twitchy, why you someone want to make that problem even worse? Raising your C.O.G. for no real reason isn't a mod worth doing IMHO.

AEV caster correction plates. Best $100 you can spend on the suspension.

Geometry correction brackets may help. Get rid of the body lift, no need for it. Even with just your suspension lift, that's a lot of height for 35's. If you were offroading with lots of flex needed I could understand, but I don't think that's what you're doing since you are running 20's.

Is the Jeep wandering all over the road, or following the crown in the road, bump steer - what's it doing?

To all,

It was a great deal from a reputable dealer and my wife suprised me for my birthday. (and the dealer had his wife was driving it so she thought it was good to go) And I am new to the Jeep family, so please keep your negative comments and give me some help fixing the issues. Now that we have that straight, I do not know why a 2" body lift was added to a 4" lift. I am asking the dealer why he made those modifications in the first place. I am thinking about trading it in for another less modified Jeep as it is. I have recieved lots of great suggestions, but trying to narrow it down to what to look for first and I am willing to drop more money into it.

What exactly do you mean by "keep the negative comments"....no one here insulted you personally. You asked for advice because you are unhappy with your Jeep's handling. It is pretty unanimous in this thread that your jeep is very poorly set up, and when you buy a modified Jeep, you should do your homework so that you don't end up spending your hard earned money on something that is going to give you grief down the road. Procomp is generally considered the worst lift you can stick on your jeep. If you don't know a lot about Jeep modification (or car modification for that matter), you should strongly consider buying a stock jeep without modifications. If you are keeping this ride, then perhaps consider installing a quality 2.5" lift, OEM control arms all around, rancho drop brackets, and keep your adjustable track bar. If you want your two door to ride properly, you are going to have to drop it.

Maybe I missed this but how do you want it to handle?

Lesson learned...you have to be careful with those really cool looking lifted Jeeps sitting in the dealer showroom.

Lotta great advice hear. Chances are, you will be dumping the body lift, going down to a high quality 2.5" lift, and maybe even going with 33's instead 35's.

Too bad the money is already spent....because it is probably better to staart out with a stock Jeep and go from there.

Live and learn...and welcome to the Jeep world!

Body lifts are easily installed and removed. That's what I would do first.

And .. X2. I don't see any negative comments. Plus ... You did not answer any of my questions. Did you read the link I posted for you ?

Any lift can hurt the front driveshaft. I have a 2 inch and trashed both of my driveshafts. The front never caused any problem in 2wheel drive....

Rancho 9000s help alot. You can adjust em and firm em up for the trail if needed. Most shock manufacturers assume what youre going to do and end up making shocks too stiff...

Wide tires and tires with a lot of sidewall ride rougher. You may be able to help by dropping air pressure some. But i consider it a worthy trade off.
