1" MML Brand?

[spearheadbill]

I'm wondering which brand of motor mount lift to get? I'm installing a 1.25" body lift and from what i've read, this is the way to go. i have an 05 rubicon with 4" rough country short arm lift (but it's more like 5") running 35" MT'S ... thanx in advance for your input

When one side of my first set of 1" MMLs broke at a weld (before I had learned to weld), I switched to M.O.R.E. (Mountain Off Road Enterprises) and they make my previous MML look like they were made from cheap tin.

Get the M.O.R.E. torsion rubber "Bombproof" mounts & you'll be very happy. The rubber keeps the engine vibrations out of the cab (as the OE mounts are made from) and they are heavy-duty enough to withstand anything. They are HEAVY.

Don't go with polyurethane mounts, that material passes vibrations far too readily, And since the rubber will already outlast the Jeep, there's no benefit to polyurethane in this application.

You can use a spacer also with utilizes your stock mm. I went ahead and got a currie mml with poly bushings because I figured with the high miles my jeep has they should be replaced anyway.

What do you think about the poly bushings? Is the engine vibration more noticeable? It would seem like a good idea for the tranny/ t-case mount to be of a comparable rigidity.

I agree that rubber mounts are better than poly for the engine mounts. I have the bombproofs in mine (rubber bushings) and can tell you, I've tortured them mightily and have had no ill effects. No engine vibs in the cab at all.

I'm goin with the bombproofs. I have a little of some sort of vibration at slow speeds when accelerating but i'm not sure it's not tire noise/vib

I went from OE rubber mounts to polyurethane & finally back to rubber over about a 4 year span. My poly engine mounts lasted about 4 years until one of the welds broke. I'll never use polyurethane engine or tranny mounts again. While the vibes from the poly mounts were not THAT bad, it was nice to get rid of them entirely when I went back to rubber.

I'll have to check those BombProof MMs out. Thanks guys.

hmmmm. on M.O.R.E's website http://www.mountainoffroad.com/Catal...dy-mounts.html it says the motor mounts are poly... did they change recently???


oh wait.. upon further review it looks like they offer the mounts in rubber styles as well

MORE makes both types, polyurethane and rubber. Look around, you'll find the torsion rubber mounts. The model is JM600L (the 'L' indicates it is a 1" lift type) shown on http://www.mountainoffroad.com/Catal...or-mounts.html

ok i see that now.

I bought some JKS 1" MM spacers for I think $54. It was easy to install and no problems so far.

My stock mounts were in good shape for a 97TJ with 130,000 miles. So maybe bad ones would require whole new mounts.

No known issues with my MMs after 165K, but my tranny mount is crap. I'm doing some fairly significant drive train modifications, and I'm approaching it with an open mind. Might even (gasp) do a body and MM lift. I'm really troubled about how my Jeep will handle in the slalom when I'm finished...

I actually dont even notice a difference at all. If it did have vibes I wonder what would be worse the agressive lugs on the tires or the engine. But hey its a jeep. If I wanted smooth id buy a cady lol

I have currie mounts and they do vibrate more than stock. But just about every time I go rock crawling I take chunks out of my tires so there goes the balance job. So I agree with Beau, you want good ride cut the top off a cady.LOL
