    Engine Mount Torque Specs

    Hey guys,
    I have looked everywhere to find a torque spec for the motor mount to the chassi. I have the energy suspension motor mounts and I am wondering what the torque spec is for the large nut that holds the mount onto the chassi?
    How about the mount to the motor?
    Thanks guys.

    Bolt that goes from mount to frame:35-50 ft/lbs

    1/2 drive impact wrench, 12-18 inch extension, about 2 seconds of trigger after it stops rotating. If you use the FFR supplied deformed metallic nuts, about half of any torque you apply to it is used up by the friction of the nut. Just get it tight, like you were tightening a lug nut, and it will be fine.
