Rear Mounts: stock or urethane?

[arturo7]

I'm using the standard bell housing that mounts on the crossmember. Are there any advantages to the polyurethane mounts over the rubber?

thanks

I used stock rubber mounts on my truck. I think you would get a little more vibration and noise from the urethane.

polyurethane is much stiffer than rubber. Like Russell said you may get more vibration.

I'd think that you would want all of the mounts to match front and rear. I've never used the urethane ones so I can't say if they transfer noise and or vibration more than the rubber ones would.
