    The boss ok'd $$$ for upgrades. After the snow in Oregon this weekend I figured I want lockers and new tires. I know I want tsl's. As far as lockers most everyone agrees that a detroit is best in the rear axle. I'm thinking about a lockright (sp?) for the front. I have a dana44, gm 12 bolt with 3:73's, th350 and 33" tires. This rig isn't a daily driver so I WANT TRACTION. Any good opinions before I buy?

    I have had bad luck with the stock axles and open diffs (which many people say are ez'er on parts). I will never lock the front till I get a D60 up there. I also know people that have had good luck with a locker up there (RaisedK5 has a lock-right in his D44 and has never broken it). I guess it just depends on how and where you wheel. To sum it up I would upgrade to 3/4 ton axles and lock only the rear. Doing this you will save money by not buying the lock-right (save about $225), a Detroit for a 14FF is only $300 (save about $200) and you can install it yourself without setting up the gears (save at least $100). So now that you have saved around $525 you will have some money to buy those TSL's and wheels you want.

    Thanks for your input. Most of the wheeling I do is climbing up and down forest service trails, some of which are steep and rutted. In the winter snow is the thing to do. I haven't seen much action in the mud and I'm not interested in rocks. Mostly loose dirt, sand, snow and occationally mud.

    Also make sure you upgrade to 73 and up axles in your D44. The stock u-joints on our trucks are smaller than the ones on the 73 and up trucks that are small to begin with. I think they will fit right in and that you will just need to use different seals (the seal kit I got came with a metal ring to convert the old axles to the newer axle seal so you would just not use that).

    Kiley,

    I've heard that a "Detroit" in the snow is DANGEROUS!!!!

    Supposedly it causes massive oversteer on both snow and ice, amd most people I've heard from know of at least one story of a friend who went off the road because of a locker in snowy/icy conditions.

    As far as traction in dirt or rocks....they are unbeatable, but I just wanted to share what I've heard so that you can do some "checking around" also....

    I am still waiting for an "Air-Locker" or "electric locker" for my 14-Bolt for that EXACT reason....!!!

    Th OX-Locker looks pretty sweet for the front. I have a Detroit in my 14 bolt and it's awsome. My K-20 gets 10-11 mpg with 33s and 4.10s, fairly stock 350 with 4spd.

    The only limited-slip differentials I'd even consider for use in snow are the Torsen or an air-locker (left open in the snow). Of course, I'm down here on the flat lands and don't do much in the snow, so a simple Eaton limited-slip differential will work for me until we get enough interest in a Torsen for the 14SF or 14FF (whichever one they come out with will determine which axle I get).

    It's hard to tell for sure. I'm estimating around 12 mpg. My tach may be off a little but it shows that I'm spinning 3000 rpm's @ around 60. I only know because I used the gps to get my speed on the highway and to track mileage.

    I have heard the same thing on ice. I wouldn't think snow would make that much difference. I was sliding all over the place on a snow covered road last weekend anyway. I have posi in the rear but it doesn't work. I've thought about repairing it but haven't looked into what it will cost. Anyone who knows more about snow/ice and lockers please chime in.

    I took your advise along with the advise of many others and decided against a full time locker. Got my bonus and sprung for an arb for the 12 bolt. I'm leaving the front open for now. Detroits sound great but I want to be safe. The arb just seemed to make the most sense.
