    Do the poly bushings really work better than the rubber bushings? I'm not talking from a durability standpoint but more from a ride point of view. It seems like they would make you feel every crack and bump in the road. There are times when that might be good but for "Normal" everyday driving I'm not sure if I really want to feel everything my tires run over, especially on a long trip. I know the way they work is totally different but is the result better with the poly bushings.

    I had WORN OUT rubber bushings and I replaced them with Energy Susp. poly ones. Ride quality improved dramatically.
    I think a comparison between NEW rubber mounts and poly mounts would give the ncier ride to the rubber.
    But, it's a truck so put on poly :)

    I can see changing the bushings in the suspension system out with poly but I just don't get why someone would change out the body bushings. It seems that the body bushings should compress not slide and that would eliminate the poly bushings as an alternative. Guess that would make the body bushings a disposable type item, like sparkplugs. Just a thought.....

    They are a little stiffer and it's hard to get them to stop squeaking, but they last a lot longer and I like'em

    The poly transmits the road to the body vs. the rubber that absorbs more than the poly. For durability poly, they will last awhile...
