    Its a vibration dampener. Reduces drive line vibe propagation throughout the rest of the vehicle.

    They can be found on some tcases as well.

    I wouldn't put one on if you're not having issues with vibes.... otherwise its just another thing to get caught up on.

    Some of the XK/WK's come with them stock right fromt the factory. Like Matt said, its a vibration dampener. My friends 05 Grand cherokee has one. I noticed it when we installed his BDS 4 inch lift last year. He has the 3.7 liter QT1 so obviously its not on all the WK/XK's cause my 4.7 liter doesnt have one. This isnt an upgrade by any means or anything thats going to prevent damage to your Jeep while off roading.
