    I grenaded my 10 last weekend and have a 14FF to install.
    I have 2.5" of lift and need to know if the shaft is going to work. I have read where it works for a 4" lift w/o problems, but the last thing I need to do is break the t-case with the drive shaft being too long.

    The reason I ask is that I will more than likely end up with 4" in the future, and don't want to re-work the shaft.

    Probably the only way to know for sure if it will work is to install everything and check it.

    you are going to need a specialty ujoint for the rear of your rear driveshaft. i bleive you would need napa # 348, that is if it uses the external clips. there is another specialty ujoint for the internal clips, but maybe someone else can help you with that number since i cant seem to remember

    I just wanted to say that you will love that 14 bolt, I dont know about your driveshaft with the 2.5" lift, but mine worked out fine with my 4" lift (as you allready knew). Good Luck
