Limited Slip Differential in Chevy Truck - Anyone done this?

[hurley842002]

Generic term would be an automatic locker, commonly referred to as a "lunchbox" locker if it just replaces the factory spider gears in your current carrier. A locker such as the Detroit mentioned above replaces your entire carrier and is a more involved installation. I've owned both, a Detroit in an 86 Toyota 4runner and an "Aussie" lunchbox style in a 99 Cherokee. The Aussie I installed and it was very simple and straightforward, the Toyota diff with Detroit unbolted from the axle housing so it was already set up, and was an easy swap.

Sounds like you are building quite the rig Stu, I'm contemplating doing a lunchbox in the front of my Xterra now that I don't have snow to worry about, I already have the factory E-locker in the rear.

ETA: Both styles referred above tend to click a bit, but in my experience the lunchbox was actually smoother and quieter than the full Detroit. The only traction systems that are mostly silent are limited slips, with selectable lockers obviously being 100% silent when disengaged.
