JPNinPA. Thank you for the quick reply.. I didn't know what it was, as I've never done a lift on a jeep..! I'm going to pull the entire coil and absorber out and see if I can trace down the numbers, and locate the manufacture and either try and get a new shock if possible or the entire assembly. Mine does not have the other shock, only the one in the coil..!! is that a problem. ??? First I have get a spring compressor to collapse it...though.!!
