    Put a 4" lift on the K5... Should the driveline be lengthened to where the shaft was originally located on the output of the transfer case? If not, how do I measure what the ideal length should be? Someone said the new travel might affect exactly how long it should be... Wanna make sure I do this right before I spend the $$$... Thanks!

    With 4” lift kits further modifications are not necessary. However a steering arm would be not bad.

    It seems that all rigs are different.
    Most drop the t-case 1" to correct any drive shift vibes.
    Most likely that is all you will have to do.

    It is likely that you will need to lenghten your driveshafts. Take a measurement from the yoke on the driveshaft to the yoke on the axle. Then take this measurement along with the one for the other shaft to a shop that can re-tube your shafts. Should be easy to find one in the yellow pages, or talk to some guys in your area who have had it done to find out who does good work. The best advertising is word of mouth. It is best to get both shafts balanced after they are re-tubed as you don't want any vibrations.
