Well, my conversion is all but done. Need to order longer fronts shocks, but other than that its done!!! Drives like a dream down the road and I can't believe how quite the suspension is over rough spots, not to mention smooooooooth...

Can't wait to get the shocks on and see how it wheels!!!

Here she is, even got her new shoes...

Keep it simple and buy the 36Rs all the way around. That's my take.

Matt
Do the 37Rs give more than 2" lift?

I went with the 37R(ears) and the 14F(ronts). No rake that I can notice. Added 6 degree shims to the front and castor came in around 6 to 7. (Would need to pull my alignment sheet for the exact numbers); 4" shackles (YJ length.)

I estimate 2.5" of lift on my light CJ7. No winch, no hard top.

Ya, that's what I said! I painted them black for now, but I'm gonna have a buddy spin the tires on the wheels and try to get them a little more naturally balanced. Try to get less than a pound a wheel...

Did you guys run into any issues with unexpected height gain? I swapped in 4" lift YJ springs from zone (BDS stickers on them) for my supposed 4" CJ springs, and I gained 3". Now my drive shaft angle is sitting at 31*. Also, I used the RRO kit.

Have you driven it at all? New springs need to settle in some times.

How old were the old springs, maybe they were just sagging that much?

Deeznutz,

My 2.5" OME YJ springs gave the advertised lift, or within a 1/4". They've settled about 1/8" in 2 years.

Here's my measurements with 32" tires.

I think the springs were pretty old. It's hard to say though.

I haven't driven it yet. The guys at RRO forgot the frame sleeves so I'm waiting on those. When I get it sitting back down on all fours, I'll compare measurements. As of right now, with 33's, I'm at 27" at the rear corner of where you measured Matt. Thanks for the measurements.

Just bolted everything up. Measuring in the same places as Matt, my tires come in at 31 3/4" and 28 1/2" under the driver side door.

Drive shaft angle is 35.5*
Rear pinion is 17.5*
2* shims

Front driveshaft is 17.5*
Front pinion is 3.5*
No shims

Springs are 4" YJ Zone of road and I have YJ 1" lift shackles.....

You need 4 OME springs,
http://www.quadratec.com/products/16090_5058.htm

4 OME shocks,
http://www.quadratec.com/products/16091_0171.htm

Front and rear YJ bushings(You need 4 of these kits, one for each spring)
http://www.quadratec.com/products/16090_700.htm

4-1.25" ID shackle hangers(CJ are 1"ID, YJ are 1.25"ID)
http://www.quadratec.com/products/12590_0006.htm

2 YJ front spring plates, left and right(or get some conversion spring plates. The CJ rear spring plates can be reused if you want)
http://www.quadratec.com/products/56008_05.htm

Longer shackle bolts(I would just get two sets of these or something similar without bushings and be done with it)
http://www.quadratec.com/products/16049_4011.htm

New ubolts(don't forget one needs to be the larger diameter for the front differential housing if you have a Dana 30)
http://www.quadratec.com/products/56009_01.htm

That's the basic parts list I came up with for my conversion(though I haven't done the shocks yet) If I've forgotten something let me know. I come up with about $1100 before shipping.

I hope this helps, it can be somewhat confusing. Sounds like even the guys selling the kits have trouble with it.

If you order from Quadratec, don't forget to call or email Joe and get yourself a forum member discount, and possibly free shipping.
This thread is awesome! Thanks for putting this all together. I'm about to treat my baby to a new lift and like all of you have decided on the OME 2.5" lift. I'll admit that I've only made it through about the first 20 pages of this thread. Way back in 2011 Eric was nice enough to post the above part list. Some of the stuff (like the shocks) are no longer in stock. Quadratec offers this kit http://www.quadratec.com/products/16090_00X_PG.htm which seems to have most of the same parts. If I go with the kit am I missing anything? Sorry if this has been covered before. With the length of this thread its a bit of information overload. Here is a pic of my rig pre-lift

Seats are very comfy. However the driver's seat has seen better days. It has several tears and the seams are starting to pull apart. I would love to replace it but I can't find a matching seat. The dude I bought the jeep from a few years back said the seats were there when he bought it. I may just replace all the seats down the road after this lift. Right now my jeep fund can only support one project

This thread is long enough just talking about the OME lift. We should probably take the seat convo to PM. Shoot me a pic of your driver seat and how much you want for it.
