    I launch in 4 hi with a manual shift transfer case so don't have the option to shift out. Holding up with 115mph traps. For those that question if it helps or not, I dead hook spaying a 175 shot out of the hole on General Grabber street tires (1.65 60ft). Try that in 2 wheel drive.

    The best place to get information on it is on the diesel/duramax forums and there are tricks/parts to keep the front end down an avoid unloading the front tires through weight transfer depending on your power level.

    Any more power on my truck and I'll probably switch over to 2 wheel drive though. Will take some big slicks and and major suspension work to keep my 60where it is now but a safer way to go in my opinion if you're looking to go really fast.

    I also have the manual transfer case...

    4hi is great for launching.....probably AWD is better when cornering an stuff, but I dont see many of you guys protouring ur trucks.

    I have used the 4hi in heavy climate condition in narrow curvy roads for 3+ hours trips over 85 and still counting.....

    So I'm gonna tell ya if 4HI might hold at mid 11's soon.....
