I am considering locking diffs for my 2010 ST and I am interested to hear peoples experience with air and electric lockers. From what I have seen on the web the ARB air lockers seem pretty good (with 5 year warranty) as do the TJM (limited lifetime warranty) but I am also interested in the Harrop E-lockers as from my perspective there is less chance of something going wrong with them (could be wrong but I am assuming that you only have to get an electrical signal to it without having to worry about seals, airlines, etc). I would really appreciate any feedback from anybody who has them fitted.
Also keen to understand that if I start off with just one locker am I better off putting it on the front or the rear??
Finally, when I select 4H or 4L, does the centre diff (transfer case) lock up and always provide drive 50:50 front and rear or is it also subject to differential action?
