Yes , there are ranger rear ends that come with traction lock differentials . Not nearly as many as I'd like . I'm putting a traction lock in mine , [ if it ever comes ] and changing the gears because I want a gear ratio that isn't stock , [because I am stupid] . I have some experience w differentials and I'm expecting it to be a ***** . If you can follow fairly simple directions , and you want to do it yourself , and you cant find the right rear end , you could buy one with the right gears and just change the differentials . It is 1/10th the work of changing gears . You could take your time doing it too . Also worst case , you'd have your original rear end , if you didn't get it quite right, you could make adjustments .
