Advice for light offroading

    Hi, I'm just looking for some opinions about what kind of mods I need to do some light off roading. I'm not really into mudding or serious 4x4 action, I just don't want to get stuck on washed out roads or at the farm. I've got an 03 2wd Sierra, and I'm thinking BFG TA K/O's would be a good start, but I have also been told that some 3 inch lift spindles would let me run a bigger tire, which makes sense, but would this be enough for what I need? Again, definitely not boggin in the woods, just need a more aggressive look and peace of mind when taking a trail to the farm. Thanks.

    Lift and larger aggressive tires are a good start...locking rear differential will work wonders in a 2wd. By locking rear differential, I'm talking a Lock-Right, Detroit locker, etc...not the factory G80.

    A friend of mine would take his 2wd s10 out with us on the trails with nothing more than some aggressive tires and a heavy right foot, he didn't do too bad.

    I would say the 3" lift and tires would be good. You don't want to go to big because than you will move the power band in the truck which may hurt more than help your off road performance. But the locker is spot on.

    Haven't even thought about a locker, works wonder huh? Guess that'll do! And also, this may be a question for the seller of the spindles I'm looking to get, but most lift spindles I see say that I need at least a 17 inch wheel for them to work right, which doesn't make a lot of sense to me. Any explanation for that?

    A bit more info on your truck will make answering some of your questions a little easier.

    Sorry, just a regular stock 2003 2wd GMC Sierra. Only thing I've added is a toolbox and Bedliner. Currently running 255/65/16 Firestone Destination LE's. Stock as they come.

    A locker will make a lot of difference...both wheels pulling, no matter how much (or how little) traction you have at either wheel...

    I had locking front and rear differentials in a 1500 Dodge Ram, I could go places in 2wd that would hang me in 4wd with open diffs.

    The advice on the locker is spot on....I would never go back to an open diff! I'm not sure why some don't like the G-80 though. I've never had a problem with mine. My 05 ccsb Z71 has been treated like a 2ton and driven like a camaro and always got me through. All terrain tires and some ground clearance never hurts though. The best advice that I have is know your limitations, and if your moving DON'T STOP.....

    I don't fault the G80, it is probably the best on-road and/or light off-road LSDs available. But for true off-road performance, a mechanical locker is where its at...

    Thanks for the input everyone. I've gotta figure out which locker to buy and get some prices, but I really appreciate the help. This has actually been my first thread on any forum ever, and it's paid off!

    One more thing though, if I went to a pick and pull and found a nbs z71, could I pull the differential out of that and use it? Or would a new aftermarket Eaton or Detroit locker be the best bet? I'm still pretty green when it comes to stuff like this.
