    Does anyone have the torque spec for the polyurethane body mounts? I installed the Energy kit a while ago and left the bolts a little loose so the body could settle while I worked on the rest of the vehicle. I now have lost my instructions and don't know the torque to give these guys. Energy will not reply to my inquiries. Please help!
    Thanks,
    JT

    I had Energy Susp. body mounts too once. I lost the instructions but if I remember, I think they said to torque the bolts down to 85 ft. lbs. Not real sure, but think it somewhere around that range.

    When In Doubt, Whip It Out!

    I don't know the specs, but I do know that you DONOT want to over tighten poly! poly cannot and will not flex if it is squezzed too tight. So what I did was use nuts with nylon inserts on my mounting bolts and then tighten the mount just until the washers/shims can no longer be rotated or moved. I did this over 5yrs ago and have had 0 issues......
    hope this helps

    Do the mounts have the "sleeves" that go in the center where the bolt goes? I just did a set on my car, and realized that I *can't* overtighten them, because the "sleeve" hits the washer on both ends before the mount can crush. Very good setup.

    I know some people won't like this idea, but I lubed the heck out of the bolts with marine lube, to keep the exposed threads, and bolt shank, from rusting, so if I ever need to loosen them again, it will be easier than it was last time : )
