    For those that have gone to poly body mounts, did it stiffen your ride? I assume that the poly has less give than rubber so it should keep the body and frame more rigid. Please post your experience.

    Didn't notice any difference, except I think the body tended to flex more, since it will follow the frame now.

    Much worse suspension problems IMO are the quad shocks in front, and the fact that the front leaves hit the bumpstops when going over any sort of speedbump or obstacle.

    I didn't notice any ride difference. My clutch (mechanical) works much better wheelin' though (the body flexes MUCH less).

    The only difference was the 1/2" or so that it added. the old mounts were shot.

    I like that mine are red and so is my blazer.

    when you have rotted out stuff and are swaping in body lift or swaping bodys around then its easyer to go poly and never need to fix it again in my opinion.

    be sure to change out the hardware as well...why upgrade to all the pretty poly stuff when you're just gonna use tired rusted bolts again...

    I was going to put in a 1" BL as well, I THINK they come with new bolts. The truck has really good looking mounts for an 83' so I figured this would be the best time to do it, before they get all crusty from the mid-atlantic winters.

    ORD body lift does come with new bolts, yes. If you are gonna do a BL anyway, its a good time to swap in poly mounts. Can't hurt, and those factory rubber ones are definitely an expendable.

    That's the set I got also - ORD 1" lift and mounts from ORD. Very simple.

    If you sensitive to engine vibration/harmonics you may notice an increase. The polys transfer vibration easier than the rubber.

    That was my experience. I immediately picked up some rattles in my dash and door panels that were not apparent before.
