RECAP and UPDATE and SOLVED
I am not sure if
@Daz7 understands or read the beginning of this thread, but I was not trying to get more lift out of my OME. I simply wanted it levelish. With the heavy kit on my Jeep it actually gave me just a touch under 4 inches of lift in the rear and barely 2 inches in the front. This did all sorts of crazy things to my jeep. I am also running 31 duratracs and do not intend on running bigger tires. I was just trying to figure out how to level it.
RECAP
The way the kit was I installed the heavy kit with the 10mm spacers front and rear because that is what comes with the kit. It wouldn't even roll out of my driveway that way. I had to lower the pan to get the driveline to turn. It bucked and knocked and was pissed. I did a 3/4 pan lower and it would drive but still vibrated on take off. My steering WANDERED really scary at 40 mph and above.
I wasn't satisfied that the kit had a 2 inch rake when it was only a two inch kit. Plus it handled bad even with the alignment. So I called ARB, and showed them a picture of my Jeep and they agreed that it had way too much rake and said it was because I had ordered heavies for the rear but have no weight or t big tires on the rear.
We talked for a while and he said that the spacers aren't always necessary and that all tj's are different and sometimes they have to cross the A's with the B's and add and remove spacers to get it right.
I don't believe anybody is buying a 2 inch lift then adding spacers for more lift. I think we are adding spacers to level it out because "All TJ's are different"
UPDATE
So He suggested I buy the light springs for the rear. I contemplated it for about a week then just went ahead and did it. And low and behold it dropped about 3/4 of an inch. The vibrations went away and then the steering got better. It started to wander at about 60 +. Still too much rake for my taste so tonight I decided to remove the 10MM spacers in the rear.
I was really sick today but decided to muster up some gumption and just getr done. I removed the rear spacers and drove it and it was super smooth and leveled out to about a 1/2 inch rake. I am pretty happy with that. I could remove the 10mm spacer in front and add a 3/4 spacer and that would level it out perfect but sometimes I do tow my quad on a light trailer so I will be happy with a 1/2 inch rake.
So breakdown what worked for me
98 TJ 4.0 5s /w winch and winch bumper and dual batteries.
OME 2.0 heavy lift in front with heavy shocks and 10mm spacer
OME 2.0 Light lift in rear with no spacers
left me with 1/2 inch rake.
After this I drove it and and it looked good so I brought it back in the shop and removed they tranny pan drop, and drove it again and with the exception of a slight take off vibration it is vibration free and the steering seems tight at all speeds now. I brought it back into the shop and re-aligned it and it was actually at 1/8 toe and I moved it to 1/16th. It didn't make any difference that I could tell on the test drive after that, but I think it is all done now.
So
@bobthetj03 @Starrs @JMT @Ranger_b0b I think my journey is finally complete. Somebody mentioned earlier I think in this thread that I shouldn't have to lower my trans for a 2 inch lift and when I finally achieved that it seems to be true. I am hoping this helps others that have questions about the OME, but I think it is important to get the right springs for your TJ. There will be a lot less hassle if you do.
For me the difference between the light and the heavy wasn't ride quality as much as road height. The heavies gave me more ride height because I wasn't sporting enough weight.
Anyway here is a my done deal.
