    From the output shaft seal on your tcase or flange whichever you have, to the center of the u-joint on your pinion.

    Just wondering why do you need to lengthen the driveshaft?

    I don't know if I am going explaining it right, but the driveshaft will bind-up at the U-joint on the diff side. That with ranchos 5000 schocks. Right now I am using stock shocks, and the driveshaft will turn ok. Also the shaft that enters the transmission use to only have about a 1" showing know about 3". I am not sure if that is ok, and I think that lengthen the driveshaft is needed.

    Ok, that's good news. Well, how long is the slip yoke? I am worried that it will slip out. I guess I going to just pull it out, and check.

    I have a 4 in lift and never had a problem with it coming out. I think most the people on here with a 4in or less have a stock driveshaft. Over 6in then id get a longer one.
