2"bb and a 1.25"bl is a 1MML needed?

Hey guys I have been reading up on my current setup which I havent installed yet but I was wondering if a MML is needed with a 2"BB and a 1.25"BL?

I think some guys are getting away without doing the mml when just doing a bb. Try it without and if you get driveline vibrations you can add it later.

Its not needed but its reccomended. A mml will fix any drive line issues you may have with a 2in lift and it will make it so you dont have to mod your fan shroud with your bodylift.

By the way I'm running the same set up your talking about.

This. It is not needed if you move the fan shroud down an inch, but it well worth it for the driveline advantages they offer.I recommend full replacement 1" motor mount lifts instead of the cheaper motor mount spacers some manufacturers offer as a cheap-o way to achieve these results.

Brown dog offers a sturdy 1" motor mount lift for $85, and you can't beat the made in America quality!

Plus it raises your oil pan and sets you up for a tt in the future

Mml is a whole new mount assembly

http://browndogindustries.com/

Mm spacers are a block of aluminum that sits between the frame and stock motor mount

You can either get 1" aluminum blocks that go between your existing motor mounts or new motor mounts that are 1" higher. My mounts were fine so I opted for spacers. In hindsight, I should have just gotten new mounts to make things simpler. It'll all be a moot point if I ever get the Savvy under armor. Still saving.

What are the advantages of one or the other? As far as driving differences?

There are no real difference, one raises your existing motor mount while the other completely replaces it

However, if you do get new mounts, get the one with rubber bushings and not poly. The poly bushings transfer a lot more vibrations through to the frame.

The main difference is your stock motor mounts will absorb more vibration than any of the 1" lifted mounts. I bought the brown dog 1" raised rubber mounts,andthe with my 4 cyl (4 cyl engine produces more vibrations than the 4.0) they still transfered too much vibration for my liking.
So I would say if your stock mounts are in good condition I would get the 1" aluminum blocks

So I'm assuming that different mounts are cheaper than the 1" spacers... Either way what is the best was to tell if my stock mounts are still in good condition?

The spacers are cheaper, and I'd doubt your stock mounts are bad mine have 236k on them and are fine....

Ok I took a couple photos before I throw in the bb and bl and this is what I found. If im correct does it already have a spacer and extended bumpstops? If so will the bumpstops work? The jeep also has 64,xxx on it should I maybe send the BB back and get a suspension lift? Any help would be appreciated.

Spacer... No thats just a rubber pad to keep the springs from rattling, you will re-use that

You front bumpstops look like they have been extended, the rear have not been

64k is nothing you'll be fine with a BB, Mine has 118k and I did a BB in May

I was going to run the 2bb and 1.25bl for a year or two and then get a 3" lift and keep the body lift. How is highway driving because im making a 1300 mile round trip to obx nc in june. Thats why i was hesitant about getting the bb over the suspension lift.

I think it rides better than stock and Im also planning on doing a 3" spring in the future

Am I the only one that noticed the "twist in" spring spacer in the front springs? The first thing I'd do is take them out and see how your Jeep sits after removing them. They were probably put in to try and level the Jeep but if you flex your Jeep any they can come out!
