Ive sold a few e lockers and all of them sold for more with gears in them then stock.   Most people run 5.29s. 
If you buy a set of gears and bring your e locker I can swap them over for 75.00 bucks. 
I know most here hate trail gear but their gears are unmarked yukons and set up VERY well.  Better then any other gear ive done. Plus they are 145.00 shipped.
If the locker is gonna go in the front axle and the bearings are all in good shape there is no need for buying a set up kit.  Also I can put either 4 cyl or 6 cyl gears in.  Doesnt matter both are the same strength.  4 cyl just requires more shimming.
