I have the OME kit on mine.It was listed as 1.5 but in all actuality its was 2 rear with 1.75 up front.I added a .75 spacer to get a full 2.5 out of the front. The front coils are the 930,rear spring is the light/standered pack CS034RB,I love how it rides.

 

If you want to know the specific height of the OME springs go to the ARB site and look under application guide.When I got my kit I purchased it from Quadratec and they didn't have the separate specs on the springs.

 

I'm in the same boat lol, wanting to know how the OME springs lift. don't want to go over 4"

 

Interesting on the OME HD leaf pack. I am hoping to pickup a 99 XJ this weekend and want to get a lift asap to run 31's. I am just going to use to trail ride basically with my family and want a good plush ride.

I am still researching options, but the XJ is all new to me. Would going with the OME HD springs (2" gain in lift) and pairing with a 1" block to get the 3" result be an acceptable choice, or are there other leaf packs out there with just as good a ride that will give me 3"? I don't want to go beyond 3" lift so as to avoid the other issues that need addressed when lifting above 3".

.....

 

No, it is not an acceptable choice to put a lift block on some super nice leafs. Use an extended shackle to get that inch of lift. OME does offer taller springs but you'll get a better ride/flex using 2" springs with a longer shackle.

 

Thanks for the info everyone. I think Im going to go with the OME HD kit...with probably a spacer in the front and adj. shackles in the rear. I want to run 31" tires...mostly for the nasty winter here since we live in the country....plus I miss by JK with 35s

 

I just finished putting a set of OME Mediums in my just purchased 92 XJ. I got over 4 inches with stock shackles. I was looking for two. three would be OK, but 4 is too much. I have not done anything to the front yet, wanted to see how the back did with and with out my boat attached. Do you think these will settle down some. If it stays at 4 inches I think I will have more front end work to do. I was planning on just adding spacers to the front springs. Also the shocks I have will not fit with the rear at 4 inches.

OME makes their products more for quality/spring rate vs height. So their stuff is not always equal in terms of height. Great ride, some ride tall when new, but settle over time.
I recommend discussing lift needs for OME with Dirk @ dpgoffroad.

 

If you got 4" for springs that were supposed to be 2" something is wrong. I put my 2" HD springs on and had about 2.5 to 3" (closer to 2.5 I think) for a little while until they settled, but they're not going to settle 2". Did you tighten your mounting bolts with the axle hanging or with the weight of the Jeep on the axle? You need the weight of the jeep on the axle before you torque everything up.

 

At first I tightened them with them hanging, but have loosened them and redid them with the weight of the jeep on them. This did correct the little bit of difference that I had in height from side to side, but I am still at over 4 inches if lift. I did find an issue that might be related to my problem though. I ordered OME CS034RA springs from Morris 4x4. That is what is on the invoice, and that is what was on the paper tags that were attached to each spring. BUT the part number that is painted on the spring is CS033RB. So now I am thinking that I have the wrong springs. I talked to Morris on Saturday morning, and forwarded photos of the springs as well as photos of how much lift that I got. They are going to talk to ARB on monday and get back to me.

I was going to put the hitch back on the XJ Sunday and put the boat on it to see how much it would go down, but after getting the brake lines on and moving the Jeep in the driveway I know have a tick coming from the drive shaft when it moves. So I abandoned that Idea as I do not want to hurt the new U-Joints I just put in.

I e-mailed ARB about their springs. This was the response that I received.

I apologize for the mix up. The CS034RA springs were discontinued and replaced by the CS033RB springs. The CS033RB is a better spring and is also modular. What this means is that you have leaves in the pack that can be removed to adjust height and spring rate. I would start by removing the second leaf down from the main leaf to get the height that you desire. You can also remove the inverted overload if needed, but I would start with the second leaf and then let the springs break in and settle before I messed with the overload. The "+" and "o" are just marks put on the springs during the mfg. process and mean nothing in the overall scheme of things.

I came home from work this night, and removed the 2nd spring and I am now at just a hair over 3 inches. I do not want to remove the overload as I am want it there when I add my boat. I guess I need to build a transfer case lowering shim, and order the stuff for my front end. I am just going to add spacers to the front for now and see how that works.
