After all the great input I did not do any lift kit, appears to not be any benefit in doing it. I did put on new Bilstien shocks which made a huge difference in ride and handling. I've realized my 2wd is what it is and I should just get another truck if I want any off road capability. From about 1980-89 I had 1964 1/2 ton 4x4 Suburban with a very beefy pto winch, had a lot of fun with that, really too bad it was t-boned by some jerk careening around the corner into it as was parked in front of my house, would love to still have it today.
thanks again for the input, Brian
If you lift it, put some good tires and a locker in the back you will go places stock 4x4s will no problem. Remember, they are only 2wd in the true sense.
Option code is G80, but that covers both lockers and limited slip diffs. In the half-ton trucks it will generally be an automatic locker, and in the big half-ton SUVs (Tahoe, Escalade, Yukon, Suburban) it will generally be a limited slip. I have both (one truck and one SUV), and both have failed. The limited slip in the 2000 SUV did explode a few years ago and took all the gears and the ends of the axle shafts with it, so I found a complete rear end and it bolted in with minimal hassle. The locking diff in the 1998 truck also failed, but less catastrophically and gave me plenty of warning. I had a trans/diff shop rebuild that one. Neither job was particularly cheap. When the GM locker is working, it does a decent job for what it is.I forget the option code
