How much? Who caries them? And is it worth the change?

More vibration, stiffer shifts. Most of the time if you keeping it somewhat stock I would go with the stocker. I broke my 1le mount in half and then broke my torque arm mount so I replaced with the energy suspension brand. A lot more random vibration and noise, prothane also makes a mount(have one as a spair).

ws6 store has the prothane.. maybe even on of our sponsors, any auto parts store with have the energy suspension.

The vibration/noise is harsh at first, but does soften over time.

If you have a shift kit it is a must because you will break the stock rubber in less time than you think and that leads to other problems like broken motor mount ruber as well.

i put a new stock one in and within an hour i tore through it... went with a prothane and after it softened up i love it. although somehow, i managed to snap the bolt coming through the crossmember when i powershifted the other day.. im thinking it was a factory flaw

To the Op, with my poly mount it does vibrate the car quite a bit more, however it doesnt bounce around or get drivetrain hop like it did before.

theyre cheap from summit, yes they're worth it. i have poly and solids EVERYWHERE there was fact rubber.

Same thing happened with me. I had the 1le mount originally and got a 15 bucks autozone stock ls1 replacement and i ripped the bolt outta it after it hooked hitting second after about 30 minutes.. lol

I know the energy suspension model has a safety feature that prevents the bolt from comming all the way out.
