Just wanted to add a note to this thread about the rear Jeep TJ/LJ springs.
There are four different versions of the springs that were used from 1997 through 2006. These are the ones that can be used on the C10. Similar rear springs could be found on the Jeep Grand Cherokee ZJ. All four versions are the same length wise but vary in rate.
The only way to tell them apart is by the color coded tags that are on the springs from the factory, they read as follows:
103AA (or 3AA) 130lb.
104AA (or 4AA) 140lb.
105AA (or 5AA) 150lb.
106AA (or 6AA) 160lb.
The colors on the tags can vary and the rates are "ball park" at best.
