I'm in need of new motor mounts. These ones I had were brand new when I put the car together. I guess they were no match for the stump puller 455.




Mine is still a street car so I would like to use rubber but would want the reliability of the poly style.

I seen in the other post it sounds like the poly mounts sit to low?

What is everyone else using?

no... the poly mounts sit higher.. my pan was sitting on the cross member... the poly mounts gave me plenty of clearance... the one you have pictured is the same style I took off...

Do you like them?

I ran them and loved them! Beefy as hell! Just be cautious if you have hooker headers, they Run too close and I melted off a bit of the corner

I run LBM so not worried about headers.

It looks like its either might mounts or the poly. Would like to hear more testimonials.

If your 455 tore up new OEM mounts, I would go straight to poly. But they will increase the vibration into the interior.

I have Mity Mounts on my 490 HP 455, but I have not put a lot of miles on them nor have I really gotten on it while waiting to have subframe connectors installed.

I have the Mity Mounts on mine as well. If you look closely at them, they are just a regular mount with a bolt run through them to tie the two steel sides of the mount together. (Can't remember if there was one or two bolts in the drivers mount, the passenger mount is just an OEM style mount.)

Yeah I'm not a fan of the vibrations from poly mounts but also not a fan of failed parts either.

I would assume that that even though I would be paying $90 bucks extra for a bolt through a stock motor mount I might be happier with less vibrations. I'm also in the works of replacing my sub frame and will be using solid mounts and eventually use Detroit speed weld in SFC. So I would guess I with solid frame connectors the motor vibration would be even worse.

I just finished the sub frame connectors... I'm still 3 -4 weeks from rolling it out though.. still WAAAAAAY to much snow...

One thing to consider, after installing solid bushings and no give motor mounts and subframe connectors and anything else that makes thing more solid is that things are going to shake as much as they ever did. You just didn't feel it before. And instead of the rubber parts absorbing the vibrations now it is all translated to you metal parts and fatigue by way of cracking and breaking is the byproduct. Just sayin, nothing's free.

I used poly bushing in the a-arms and rubber on the frame thinking it was a good compromise.
My reproduction body mounts are looking pretty poor after 5 years. They just don't make the rubber like they should.

Going down a smooth road and feeling how much the door gaps change on my convertible is amazing. THis is my push for solid mounts and SFC.

I would still like to use rubber mounts for the motor but I'm still up in the air about it.
