Now that this technology has been out for some time and used by some (or most) of us, I think it'd be a great idea to share our experiences on where they may benefit, and where they should never go.
I'll start off with a POOR experience in MOTOR MOUNTS for my 6.5, not only was it a curve ball to my mechanic having to reuse old clam-shell housings, but resulted in negligible to negative results. Idle quality has become absolutely terrible, I'm almost embarrassed to have people in my truck if we are wading through traffic because of the onslaught of rattles when stopped while in Drive gear. Putting it in Park reduces the noise some, but no where near eliminates it. Ride quality while driving is good, but there's plenty of room for improvement.
I also replaced the TRANNY MOUNT at this time, so my culprit could be the combination of the two, but I have read lots of good results with tranny mount alone (when it was an isolated upgrade, unlike mine).
I caught myself looking at poly frame to body mount bushings, and thought: wait, these may not be best here. Basic logic tells me that soft, forgiving, run of the mill rubber will absorb and dampin my idle tremors far greater than stiffer, rigid poly replicas. Maybe if poly was OEM material at the time, it's benefits could have been implemented into the truck design, but that's not the case. I think it's more of a marketing scheme, cause the science is clear, in certain applications. It's certainly not universal. The demands of the sway bar bushings on a light duty pickup ≠ those of a tranny mount on a outlaw pro mod drag racer. They are the same as much as a sloppy joe is a rack of veal ribs in that their both FOOD.
Please share your experiences in swapping out factory bushings with ANY brand polyurethane bushings. Energy Suspension being the clear 'name brand' in the field.
Anyone use these in sway bars? Tie rod ends? Body to frame? strut/shock mounts? leaf springs?
