I've been on the hunt for a 3x locked 80 series. I've passed up several clean trucks because they don't have OEM Toyota diff lockers. Does anyone have any experience with the Harrop/Eaton e-lockers? I like the idea of an electromagnetic locker, rather than a solenoid, because I think it would be more reliable. So in that regard, I suppose the Harrop's are better for me. Anyone have an opinion or direct comparison on the Harrop e-lockers vs. Toyota OEM lockers? Should I be considering 1x locked trucks too? Not interested in air lockers.
