If your going to use it for some offroading activity you might want to swap out your open end axle for for a limited slip one. I'm actually going to be doing that in about a half hours time (got the truck all jacked up and swapping out a 3.08 open end (
) for a 3.55 LSD). Its not too complicated, but it can be a pain if your hardware is rusted (U-bolts and such). Its also not very expensive if you do it yourself either, I got mine for 500 bucks here in Canada and I'm sure you could find something cheaper in the US. Other than that the only cost is a little brake fluid and differential fluid and friction modifier.

Either way good luck on the install

Thanks for good luck it went really nice and breezy. 3 hours then road test. I swapped it out not only for the LS but the gearing too. I priced out alot of stuff and this avenue was the cheapest. Makes a nice difference, lots more grunt than the 3.08 and the LS makes for mad snow donuts in the parking lot.
