I installed an OME HD kit on my 08 Rubicon Unlimited and am running stock tires with spidertrax spacers and NO front adjustable trackbar. I installed the OME panhard bracket in the rear. The bumpers are stock for now. I used the HD kit because I plan to add an AEV front bumper and winch. I have about 1500 miles so far on the lift with NO ESP issues at all...ever. I have only had the light come on once, and I was going sideways down a gravel road so I assume it was doing it's job. Total lift is 3.5" in front and 3" in rear.

I also installed an OME HD kit on my brother-in-laws 08 Rubicon Unlimited. He has a 1" spacer added in the front and is running an AEV bumper and winch. His tire size is a a 34" (305/70/17 Goodyear MTR) and NO spacers and stock wheels. He does NOT have a adjustable track bar in front but I did install the OME panhard bracket. He has about 2500 miles on his lift now. Total lift is 3.5" in front and 3" in rear. The front dropped exactly 1" with the bumper and winch setup bringing the front from 4.5" back to 3.5".

Both of these lifts perform perfectly. Neither of us have EVER had the ESP light (other than the incident above) come on during normal or aggressive driving. The axle in the front is off center about 1/4 inch or less and is not noticeable.

From what I have read, all of you having ESP issues changed the front track bar or the control arms. We have done neither of those and never had an issue.

 

The OME is a great lift. The ride is softer than the stock rubi shocks. It performs great both on the trail and on the highway. If your steering wheel has been re-centered after you installed the OME lift, then I too think your ESP issue is due to your axles being off center. Front and rear adj. track bars should get your axles re-centered and fix your ESP issues.

Good luck.

 

as long as your happy with it thats all that matters

for 700 bucks and...4 shocks and 4 springs......seems a lil much!

 

OK, I just finished installing my OME HD lift in my 08 rubicon unlimited. Multiple issues. First let me just say that I have NO issues with the ESP light. The ride is infinatly better then the stock rubicon springs and shocks. Performance wise, i didn't adjust my steering rod because it was only off by a subtle amount and didn't bother me. What I do see is this:

First, the install was very difficult in that I had trouble getting all 4 springs into place given the limitations of ther brake lines. I stretched them to the max (even after unbolting them) and I had to manually compress the springs to set them properly.

Second. After getting everything together and re-torquing everything I noticed that the L rear end sits well over an inch lower the the R rear end. Also, The L front end sits about 1/2 inche lower the the R front end. From a geometric stand point it seems that the stock trackbars are to blame but David doesn't think so. (chime in if you are here). The rear springs do look a little bowed but its subtle.

Third, the sway bars are off from parallel by almost 15 degrees in the rear and I know they should be about parallel so I'm worried about that.

From the drivers standpoint it drive normally and rides even better. but the assymetry in the cars geometry really bothers me. By the way I got the HD kit because I have an ARB bull bar with powerplant winch on the front. Stock bumper in the rear.

Anyone have any suggestions? Do I need adjustable track bars? Extended sway links? Control arms? (I hope not) Thanks

 

I went with the JKS adjustable track bars to center the axle, although I don't think that they were off center quite as much ar yours. Most people will suggest adjustable track bars. However, If I were to do it again, I would have gotten new axle side track bar brackets. Mostly, because what you mentioned about the angle of the track bar. When I have to dynamite my brakes I get a twist to the chasis. I'm pretty sure I can attribute that to the steeper angles of the track bars. I have a new currie braket waiting to go on the rear now, Tera also makes a nice one. I'll be looking at a high steer kit next to address the front track bar angle if this doesn't solve the problem.

 

Have you made certian that the rear springs are rotated and seated properly in the lower perches? That could give you a higher side if they're not both seated fully.

As for the front, I was told by ARB that if for some reason one of the front springs appears longer than the other... then to place the longer one on the drivers side. The weight of a person in the drivers seat is usually enough to level the Jeep.

I would echo the majority of OME users here and say that you probably should get some adj. trackbars in the near future. I also would say it's not a bad idea to get extended sway bar mounts too. The stock fronts IMHO are just too short after the lift.

 

I just ordered front and rear trackbars and extended rear sway bar links. The stock rears will go up front.

 

I took another look and they appear to be seated properly. The front springs do need to be rotated into place but the rears don't have a notch. They are seated squarley though.

 

I have a TF BB with the OME HD front springs and they do 2 things really well. They ride better than stock and they flex like the HULK!

I have a heavy winch bumper and the front HD springs are just as tall as the stock springs with 3.25" of lift. I added a 3/4 spacer in the front and they sit level with my TF 2.5 Spacer in the rear.
