Well after some fun at the dunes I seem to have broken one of my motor mounts in two places. I've found several different replacements. I am definately not going with a solid motor mount again. I have found both stock rubber and aftermarket poly motor mounts, but i'm not sure what to use for my application. I like how the poly is supposed to transfer power better, but also noise and vibrations. While the rubber dampens better, but has a shorter life and is less resistant to oil damage/deterioration. My mains concerns are either the poly won't flex enough, or that if I use the stock rubber i'll just break another motor mount down the line. Anyone have first hand experience with the poly mounts?

Here a couple pics of the damage.

 

rubber mounts have been used for how many years? i dont know too many people trying to replace stock mounts because they are wore.

I am not a big polly bushing fan because I have had one wear out on me several times. they are not as forgiving.

 

poly would be ok in a car. but a truck that gets more of a rough ride will wear them out. rubber will be the best for the motor and the mount itself. Just be sure to keep an eye on them with time

 

your not turning 500+hp regular mounts will do just fine

 

Thanks for the input guys. I'm going to keep it simple and go with the stock rubber mounts. Should help my ride out a little bit.

I'm also going to build a new cross member for the trans while I'm at it.

 

Haha well I got the new motor mounts in yesterday from Advance Adapters. Very thick steel plate that should hold up far better! I also got the motor pulled and found out I broke both motor mounts! Woot! The broken mount pictured was broke in two different places.

 

Gotta love it! lol
