Hey guys. I am in the process of getting all the parts for a D60 buildup. Will be 4.56 geared diff. My '80 is a part time daily driver for the most part. I would like to be able to go offroad a lot, no rocks around here, just good old crazy mud, and deep snow. However in the winter roads get icy, and, it does see a fair amount of street driving. From everything I read, most ppl. don't like having the front end traction aided on any kind of ice/snow. So here is my question. If I get a posi, or a locker for the front (Detroit or a True Track), and run on the street with just one hub locked, will this work ok, be hard on the diff, or be a total waste of time? I think the best opton for me would be the Ox cable locker, but its a STEEP price to pay for a truck like mine. For the 14 bolt I think I would either go with a detroit locker, or the Eaton posi. My 05 dodge has a limited slip out back and open diff up front and it does OK on the ice/snow with the same tires chevy will be running on. In fact I feel there is more traction with the dodge then chevy, but the dodge is a bit more tail happy on ice. I live in Calgary, Canada. Let me know what you guys think before i start buying my parts. I want this truck to be a good combo of daily driver ability and a decent offroad rig. I think the 4.56 gears it has now are a bit steep for highway, but with 37" tires should be reasonable, while still maintaing the gear ratio that would work well with even 38.5" tall super swampers. I could step down to 4.10s during this build, but, am thinking it might be taking a step backwards if I ever put big tires on, or, want to resell the diffs. Thanks, Igor.
