Ok, hear me out first before you go posting about limited slip differentials and such. I have an '03 Silverado 2500HD that is 2wd and does not have the G80 posi-traction limited slip differential. I live in Utah where winters can be down right brutal some times. I am wondering if installing an aftermarket LSD, posi, or even a locker would be beneficial. I don't go "off-roading" or anything like that (I would have bought a 4wd for that). I just want control when I am going down the highway in a snow storm. Occasionally I will pull a 6-7,000 lb travel trailer with my truck. So I don't what something that will burn up. My father is a mechanic and has been for over 40 years and he tells me of people who come into his shop and want the G80 removed from their truck because it keeps burning up. I have looked at other Eaton and American Axle differentials, but they all seem to be the same with exception to the electronic or air lockers where they are manual. I have a friend who says that the automatic engagement and disengagement of the LSD is somewhat frightening when it kicks in going down the highway. You are never sure when it going to engage/disengage and when it is not. Is it worth it? Thanks in advance.
