I have an Eaton elocker I love it no fidgety air lines and it comes with everything one needs to control it, Ox lockers one has to buy the cable kit separate but one note on the e-locker make certain it is for the high pinion dana 30 there is a difference in the carriers for low pinion. also if one goes with the Eaton the standard Dana 30 carrier bearings and races do not work if needed I can look up what the correct parts are.
