I've been looking into changing the rear open diff out for something a bit better, I know the ARB air locker works but it's kinda pricey and I also want something that will benefit me on the street seeing how my XK is a daily driver in Colorado. (snow) Correct me if I'm wrong but from what I've been reading I am best going with a limited slip like the Eaton Detroit Truetrac (912A553) over an auto locker like the Detroit locker (187C179A) or any of the lunch box lockers like Aussie,Lock Right etc..

From what I have read and seen videos of the auto lockers are noisy, clickity click click around corners and while gassing through corners they may lock which will almost cause you to drive it in a whole new manner.

The limited slip of the Truetrac also has it drawbacks, if one wheel is elevated while crawling this may cause the unit to open up leaving you with a similar setup as before but this can be overcome with creative braking using the e-brake will be enough to "lock" it back in? We all know the XK has a tendency to left a leg now and then.

I'm not quite sure what to do, leaning towards the Truetrac anyone with any thoughts??? Input??? I think having a new rear end may be a benefit especially in Moab this spring. Keep in mind "Daily Driver"
