Locking Diff Install Advice

[easymoney]

I'd like some kind of a locking differtial on my 2013 SSV. I frequently tow up 7k lbs with it, so I have to keep that in mind.

What would be the most cost effective solution that I won't tear up by towing?

About how much should it cost to get installed?

Thanks in advance, guys.

Seems like its easier to just buy the eaton locker and install it than doing a swap. I really like the factory eaton locker that comes with these vehicles. In the ice or mud you can tell it is locked, no limited slip junk that rackets when you turn
