    I tore a motor mount on my last wheeling trip and rather that replace it with a stock mount that will break again I plan on upgrading it. So far the only ones I've found are from IronMan Fab, they look like they will do the trick, but I wanted to see if there are any other options that I might have missed? So if you know of another upgrade option, or if the ones I found are the best, lets hear it.

    I found these while looking to see if M.O.R.E. made any for the ZJ.

    I like the price of those better, I might have to give them a try.

    I ended up going with the IronMan Fab mounts. I had to dremel out one of the four mounting holes on each motor mount because it wouldn't line up right, now that they are in I get a lot of vibration right off idle, kinda sucks, but I don't think there is anything that can be done about it. I'm going to go back over them this weekend and see if I forgot to tighten something with the mounts all the way just in case that's the cause of my vibration.

    I have had a couple issues getting IronMan stuff to fit as well, but once it's in they've all been great. Curious as to what is causing the vibration, are they a poly mount?

    The mounts are rubber, but they have what appears to be a spring eye bushing in them that the motor mount bolt goes through, which doesn't have much if any give. As far as the vibration goes, it's only right off idle then it goes away, and I think it has to do with the motor mount bolts being slightly smaller in diameter than the sleeve in the motor mount bushings. I'm contemplating putting the stock passenger side motor mount back in to see if it reduces or eliminates the vibration, and since the passenger side mount should only be getting compressed I think it should hold up better than the driver side.
