After running different limited slip diffs and Detriot lockers in Both my Jeep and my 71 F-250 , I settled with Powerlocks in both . The 250 has much better road maners in winter ( the Detriot was trouble on crowned roads ) . The Jeep has never broke anything offroad even pulling a jeep trailer on my backyard trails ( Rubicon and Sierra trek ) . When building the units , set the clutch packs as tight as you can and use good syn oil with the friction modifier . There is better selectable lockers out there , but they cost more ,,,,,, olllllo

That is a very nice heavy duty LS units under full power expect 90% lock up which is pretty good for a LS. If you need to rebuild it its really simple and the parts are cheap Dana Spicer Part 22233X - Dana Spicer Power-Loc Clutches also avoid adding to much LS additive to the fluid. In my 76 I run almost none and it gives very nice lockup and no clutch chatter and I inspect the unit and the clutches still look great

I am running a Power Lok in the front (full spool in the rear) of my 79 Bronco, and absolutely love it. It's well worn and still hooks both tires most of the time. I recently installed one in the rear (Dana 70) of my 84 F250, it's my plow truck/ tow rig/ work truck. I can't think of a better differential for this application, it performs like a locker but with the smoothness and flexability of a limited slip. It's a great unit I love mine.

All Ford front 60's use 35 spline axles, rears are 30 spline so unless there is some outside chance that the rear 60 was converted to 35 or was one of the rare factory 35 spline axles you will have to change the side gears in it.
