I know there are several lockers out there for the rear of these trucks, but does anyone make one for the front? What "size" diff/axle in in the front of these trucks?

 

Front lockers are NOT a good idea on a daily driver that's driven on the street.

Front diff is 8.8" and it takes reverse cut gears.

 

Just trying to see what options are out there. If I decide to put something it would have to be a selectable locker, like an ARB or an ox locker. Seething that would work as an open diff until I needed it locked up. Thanks for the help
