I am going with e-lockers. Actually I am going with the Ultimate 44 running 4.56 gears and a e-locker. Will be putting 4.56 gears and a e-locker in the rear.
Typically when you hear of an air locker failure, it is the air line that has actually failed, not the actual locker itself. You hardly ever hear of an ARB locker failing...but broken air lines seem common, and when the air line is down, the locker is down.I’ve heard of a lot of air lockers failing. I think a e locker is more dependable.
