First a Disclaimer. I have a
Whopping one run on my current setup. and a few weeks of DD.
I am running the LC poly motor mounts.
One old stock transfer case mount (front position)
One new HD transfer case mount (rear position)
I had to buy a new mount when I went to the dual set up because I didn't have an extra. I tried the HD one that Marlin sells from 4x4innovations since it was quite a bit less in price. If you already have two, i would probably just wait unless you are having issues.
My theory for placing it in the rear position was that that is where the 4.7's are. And since they put out extra torque, i figured the extra beefyness would help there. I could be wrong though.
Is there more vibration you ask?I find it to be negligible. I notice a little more foot tickle at idle, and some when accelerating from a stop light. after that it is smooth as silk, even at highway speed. I love it.
hope that helps.
