Yeah, you need to upgrade the thirds or your gonna keep busting em especially since your pulling other vehicles. I know what it takes to yank a vehicle out of stuck. The DII's are not my favorite for much other than the stock ride on the highway. 255's are stock tire size for the 18" wheels.

 

Man but this thing is a beast bro! No joke their was a humvie with swampers and he couldn't do ****! I pulled an avalanche 1/4 of pure mud....the truck was in neutral because it was heating up! I guess I do put my truck thru hell. But after less than a week of usage it popped... so correct me if I'm wrong but the limited slip is a t case???

 

Nope, it's a differential. You pop out your thirds front and rear and replace with new spools. The limited slips can have planetary gear sets but they're beefed compared to the Rovers. Do your homework, read up on em. With the limited slips you have to drive a little different on road than your used to, a little lighter on the throttle than normal. Like I said once you beef up the thirds the next thing to go is the axle shafts, they either twist or snap. The DII has funky hubs too, I'm not a fan of axles going through the hubs, just more splines to twist. Check out Lucky8's website for lockers and posi's.
