    Depending on how much room is in your slip yokes will determine if 2 more inches will warrant extending your driveshafts any. I'll venture to guess you should have them lengthened, but it will probably still have enough contact to drive around.

    I lifted mine 2 1/2" from stock and kept the stock lengths for a while. Eventually I had them lengthened and a lot of vibration went away afterwards.

    Basically, I'm saying you'll just have to lift it up and see.
