Auburn ected is the selectable that is a limited slip when it's off, I would recommend that, but I know your truck has 4.10's and 30 spline axles, so you would either have to upgrade to 35 spline or regear to 4.56 or higher numerically. It is only available in a 4.56 and up for 30 spline, and in 35 spline it is available in both 4.10 and down or 4.56 and up, from what I can find.
