Do you mean the whole rod, or the part that fits in the end of the rod with a spring under it? This piece is a the bypass valve and is common failure with a long thread here:
Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)
Jeep does not sell this part, but on the last page is a link to a Motor City Mechanic youtube video where he is testing a Dorman third party replacement that should be available soon. Check that thread for some workarounds, including using a machine screw, or buying the whole filter assembly ($120-$140?) just to scavenge the bypass valve.
If the whole rod itself is broken, you may have to replace the filter assembly.
