Should I do a motor mount lift without a body lift?

My stock motor mounts are on their last straw before giving out at 122k miles. I am pondering the idea of buying a 1 inch” lifted motor mount like the MORE ones when I add a 2 inch suspension lift (No Body Lift). I am wondering two things: Is installing a mml worth it? And will everything clear the hood and trans tunnel? I do plan for a tummy tuck in the far future but nothing particularly soon. I have a 98 4.0 with the 32rh.

I have seem people always say that. I have only been looking for rubber because of it but what exactly is superior about them. Are poly mounts weaker and maybe a but more rigid?
It depends what your doing wether a poly mount is superior.
A poly mount transmits more engine vibration to the chassis. On a DD this make the driving experience less enjoyable. On a race car......

What is the rationale for considering it? Is it because you fear vibrations from the suspension lift and this is a possible fix?

My main thought is I would like to do the motor mount and body lift combo with a 2.5” lift and a bit of a tummy tuck in the future, much sooner than when I would need another new set of motor mounts. I don’t have the funds for all of this at once and my plan is just to do a basic ome lift for now and slowly piece together the final plan. It is fully based on if it is worth it to buy MORE replacements to then buy 1 inch ones in a few years or just go straight for the 1 inch right off the bat.

I’d just get OE replacements and add an aluminum block 1” spacer when needed.

I didn’t even think of that. Unless there is some weird reason thats a metal spacer isn't as good as a taller mount that will be what I am doing. Thanks for the idea!
That sounds a solid plan. I believe if you did the mml before doing the body lift you would have had to deal with the fan shroud. I guess the only disadvantage of this plan is what to do if you do get vibration from the suspension lift. My understanding is there are only three ways to address it: sye / dc drive shaft; mml; or, transfer case drop. Given you envisage a tummy tuck in the future I guess option three is going in the wrong direction. Option one is much more money, so if you can hold fire on the new motor mounts until after the suspension lift it would be ideal. If not then I guess you just add the riser blocks sooner than the ideal plan and deal with the fan shroud.

Let us know how it works out.

A tuck can cause the fan to hit the bottom of the shroud necessitating an MML,
 
The Mopar motor mounts are a solid product. I did the aluminum blocks under them but still had to do a 1” Body lift. I had some Metalcloak bump stops hanging around & used them for my body lift.

I suspect your looking at the mounts thinking the gap between the rubber and the cage is a problem.
 
You can have my savvy poly mml when I switch back to stock mounts with a lift block. Not sure why you would want them, though.
 
@Ejforan

Do a mml if you have driveline vibes... even if they are minor vibes.

Brown dog mounts work great for me. Rubber ones better isolate engine vibrations.
