I 'm running Detroit lockers front and rear, but I do a lot of off road travel. But I'm old and like less moving parts. I've installed several different traction devices, If I had to do it again I'd install a selectable locker. Weather it be electric or air locker, it would drive better than a Detroit. Unlocked, you won't know the selectable are there. The Detroit has a lot of quirks, but you can't knock the performance. I have installed E-lockers, I haven't had any negative feedback. Air lockers have an added advantage, on board air. I'm not affiliated with any company. I have friends that are running zip-lockers and ARB lockers, in all combinations. All are happy with the performance, I installed ARB's in my son's TJ. Which see minimal off road travel time, for now anyway. Gear ratios are a different topic. If I can help, please ask, Ron
