Eaton E locker for dana 30. Part no. 19817-010. Axle shaft spline count is 27. Fits 3.55 and numerically lower ratios. The locker and bearings are used, and have about 20 thousand miles on them. The gears are 3.55s revers cut (high pinon) from my 98 xj and have 156 thousand miles on them. The wire harness is new. If you don't want the gears I can remove the ring gear for you but the carrier bearings won't survive. The price is the same with or with out the gears. $450.00 plus shipping OBO. Everything works, the reason for selling is I went to lower gears and got a new E locker. I'm in Bradford PA 16701
