Anyone changed the stock diff to locker on 2012 4cyl 8"?

I have a very modified 2012 single cab 4wd which does quite well over the rough stuff with atrac, but I am very concerned about the two spider rear 8" center breaking in the middle of a nightmare trail. I have a 9" Ford LSD which is the right width, but I need to retain the Toy ABS/tone rings. I could have Diamond build me what I need, but short of that, anyone running a locking diff on the puny 4 cly rear end? Has anyone swapped an 8.4 rear into this truck? I like making it to the end of the trail, not begging for a pull.

 

Just beat it up till it breaks. Then do a swap
