So are you planning on adding the 1.25 bl to the already 3" body lift? If so, wow. If not and you are replacing the 3 with the 1.25, then you wouldn't need the mml lift at all.

I would plan to install them both in the same day. Takes just a few hours to do the MML.

I installed both a body lift and MML on my TJ last week. I installed the body lift one day and then installed the MML a couple of days later. That seemed to work fine for me.

I did BL and then MML, using the JKS parts. In your case, I would remove the fan shroud hardware and the transfer case linkage, then do the MML, taking advantage of the 3" of space in the old BL. Then I would reduce the BL to 1.25", then I would reinstall fan shroud and TC shift linkage.

Before you start, back off on the transfer case skid bolts a couple of turns so the skid can move around. Your last step would be to tighten those bolts.

I did the BL first, although it doesn't really matter. Took about 2 1/2 hours to do both.

I would normally say do the BL first. An extra inch of room under there wouldn't hurt the mml install. That is what I did.

But, since you are swapping a 3" for a 1" BL, do the mml first.

i have a couple of questions about the body lift and the mml . if you have the mml and the body lift do you still need the extension brackets for the transmission and /or the transfer case ? and if you have a suspension lift how does the mml effect the geometry of the drive line?

That all depends. Every Jeeps seems to be just a little different when it comes to this stuff. Some doing the bl/mml at the same time don't need the TC linkage drop bracket, and the instructions say that too, if I remember right. Mine kept popping out of 4lo even after adjusting the linkage, so I used the bracket and did not have a problem while I still had stock linkage.

A MML will slightly help with driveline angles as it lifts the front of the motor, and causes you tailshaft to tilt down slightly. Will it be enough to not need a SYE/CV shaft or a TC drop? It all depends on your Jeep and what lift you are running. For my Jeep, I had a slight driveline vibe after installing a 2.25" BB as my first lift, the MML cured it.
