    I thought I was going to need my rear driveshaft lengthened after I put on my new lift, but the splines arent showing any with the truck all the way in the air. It has a 4 inch shackle reversal, 1 inch zero rates, and 2 add a leafs for about 8 inches of lift. The pinion angle is actually very good too, I was surprised how much the shackle reversal angled the pinion, it looks close to perfect. I can get my shaft lengthened through a friend for nothing if I need it; hes doing the front too which had about a half inch of splines showing at full droop. If the splines arent showing at all, that means its long enough doesnt it?

    if its a slip yoke rear drive shaft, you wont see splines. you dont want too much more than 1.5" of the shiny slip yoke showing.

    The shaft has splines on it that slide into a sleeve on the back of the transfer case, is that what you mean by a slip yoke? I didnt think what I have is called a slip yoke.

    It looks like the first one except the slip shaft is on the transfercase instead of the rear end.

    he has a fixed yoke 205... u should be fine with the stock shaft. i had the stock shaft lengthened for my 8" on my k5 which has a shorter wheelbase and it worked, jus had vibs. when i added zero-rates, it now longer worked.
    just get them lengthened

    So should I worry about getting it lengthened if no splines are showing at full droop? I was lookin at it today and a question came to my mind, does the axle move back some when the springs are compressed with a shackle flip? If so, the shaft would be sliding out wouldnt it? I dont know of any way to test it since my springs are so stiff (it has 9 leafs). As far as the angle goes I know its okay, I just dont want the shaft to fall out.
