Here is a LSJ  Rebuilt Supercharger for a 2005 thru 2007 Supercharged Cobalt SS and Ion Redline.  New needle bearings and recoated rotors.  Selling it cheap so no returns.   Lower 48 states only unless you contact me ahead of time. Listed locally so I reserve the right to end auction early. No Snout on these ones I can add a snout , new coupler and oil for $100
