    If i were to do a 6 inch lift on an 80K5 would i need to get the drive shafts extended? and do 3/4 tons have longer drive shafts and if they do could you use them instead of getting the ones off the Blazer extended with a 6 inch lift?

    Thanks for the help

    Only difference w/ 3/4 tons is the axles and the size of the u-jts/shaft... not length of the shaft. Usually you need a couple extra inches for both front and rear

    would i have to rotate my axles a bit to get angles right to reduce vibration or will they be fine in the stock position. I got a 10 bolt up front and 12 in back.

    This is going to be my first lift and its my first vehicle so I am just trying to get everything figured out before I go ahead with the lift

    thanks for the help.

    Well it depends on what your plans are. With 6 " of lift there is a number of different question marks that happen on every truck. How do you plan to lift the rear? Blocks? Shakle flip? Springs? Blocks are usually angled.... springs will need a degree shim installed to point the pinion up a bit more and you will need to drop the t-case. You'll need about 2" added to the rear driveshaft and the front one depending on your offroading and flex issues maybe be ok w/ just a 1" sapcer from Superlift. Vibes can be a PIA w/ the 6" lift so I went a CV shaft which I think will be easy enough to justify considering it was only a 100 or so more then a extended stcok shaft... now I have an extra shaft in a pinch for the slip yoke tcase and I will save the extra money easily in saved time and less u-jt replacements.

    I have lots of pics of my feshly installed lift if you have questions feel free to send me a pm or email. I haven't quite found the time to get them updated on my webpage.

    Where'd you get your driveshaft from? I want a slip yoke NP 208 shaft with a CV joint and everyone says they won't make one.
