Question, I know us LJ guys can get more lift without an SYE. I was wondering HOW MUCH.

2005 LJ 6 Speed
1” BL
1” MML
UCF Ultra Clearance Skid
UCF LO-PRO mount
1.75” Coil Spacers w/stock springs

From what I gather from talking to UCF directly, the ultra skid and lo pro mount will rise the T-case 1.5”, with the 1” BL the transfer case will be a half inch closer to the tub.

Assuming the skid doesn’t cause the driveline to incline towards the rear, I am looking at 3.25” lift as seen by the rear transfer case yoke.

This setup sounds doable, right???

I would not be opposed to putting a .5” spacer on the transfer case skid making the effective lift 2.75” and returning the tub to transfer case clearence to exactly stock.

*the reason I highlighted the transfer case to tub clearence is not for possible contact, but rather to determine if there is an incline that will cause more angle at the yoke/ujoint.
 
I would guess you would be fine and start without the spacers on the skid. Raising the TC 1.5 with the skid and 1 with the MML (Making a net 0.5" increase on the rear output of the TC). Then 1.75 all over with the coil spacers. 2.25 total. Although the angle will be sharper with the 0.5" because its just the TC increasing and not the whole jeep with 1.75"

You will probably get vibrations more than normal because of the lopro mount

If this is your shopping list, then get the 1.25 BL.
I realize my Rubicon 241 is larger, but an extra 1/4" is always nice.

I have the MORE rubber MML and a poly tranny mount now, it’s not bad. I’ve had TJs in the past with a MORE MML and LoPro and think it was smoother than this poly mount. Regardless, neither are that bad.

That’s good. I just didn’t want you to install it all and have more vibration than normal and think you need a SYE when it might just be the lopro. I have the UCF skid but not the lopro
 
No matter how many times it's asked it has no easy answer. Just because somebody else does the exact same thing doesn't mean it'll work on yours. Every Jeep is different. Do what most people get away with and plan on having problems, that's the smart way to do things. It'll probably work but prepare for the worst. Nobody here can promise you wont have issues, what they can do is tell you what wont work. Listen to that advice and try to find what does work. I can tell you flat out the UCF ultra plus 1.75" of spring lift wont work. That's what 5" of lift, seems outside of reality to me.

How does 1.75 plus 1.5 equal 5 ???
 
The bottom of the skid may be raised more than what we are calculating but the net raised amount of the TC output should be 3.25 (assuming UCF is right). I think I was wrong earlier talking about the MML reducing the raised amount. It doesn't really reduce it but it will affect the angle of the driveshaft to TC output which is what you are really concerned about.
