Vibration? See I don't get why people say that, I had absolutely no vibration after installing solid ones. Now when I installed solid TRANNY mounts there was a noticeabl difference, but motor mounts? Not a damn thing, maybe it's just me.

 

Jacob would have sheared the bolts off the solid mounts also, but the solid mounts would have landed on the track when the bolts broke. The aluminum mounts have the same thru-bolt design but there is nothing the keep the bolt captive if the hardware breaks, sending the mounts flying.

 

I've got the mounts and I really like them. I don't drag race, but I've done an autox or two when time permited. When I first installed them there was quite a bit of vibration felt in the cab (compared to broken stock ones) but now that these mounts have broken in I don't notice anything. I'm making quite a bit less power than others here, but have had zero problems.

Keeping this objective and avoiding personal attacks, the design as described and seen in the photographs is no good. The poly bushing CAN compress (and one would think it's intended purpose is to damper compression). However, there is nothing damping the rebound which follows the implied/expected compression.

On rebound, the bolt takes a hard, direct hit.

It's a bad design, thats all there is to it.

That's a pretty grand, and grossly incorrect assumption. Home Depot has nowhere near the required selection of metal and composite fabricating materials, and metric fasteners.

 

Come on people, let's keep the attacks minimized.
There are some pretty respected names in this thread, and none of you deserves to be attacked like this.

Anyone who has taken apart the stock rubber engine mounts knows that the top and bottom studs are not connected physically with the exception of the central rubber core.
The stock rubber engine mounts have ends with a stud - plate design with a center core of rubber.
The stock rubber engine mounts are designed to damp in the compression and rebound vectors.
The rubber compresses and stretches (evenly) to damp engine movement.

This particular engine mount damps compression no problem, but the rebound damping is not the same (design) as the stock rubber engine mounts.
I don't really care about what FD owners pay for the Gotham Racing stuff (do you really want me to go off about FD owners? ), but this really has nothing to do with us FC owners.

At the very least, one fact remains that this particular aftermarket engine mount is not the same design as the stock rubber engine mount, period.
You can make you own conclusions from that.
