would this work on my rig?

line locks cannot be used as a cutting brake. you'll need a cutting brake to work as a cutting brake.

they're commonly found on dune buggies for steering in wheels up situations.

Yeah, they can. You just have to run two lines to the rear instead of just one. It's not a high-speed cutting brake. It's a tight-trail cutting brake.

Here's a discussion about it:

it would also require twin sticking the transfer case. to work either way.
