    I'm just putting a 4" lift on my '91. (stock rear springs with shackle flip).
    Will my rear drive shaft be long enough or will my slip yoke drop out of my 241 on full droop?
    Anyone with 4" lift running stock d/shaft with no probs?
    Thanks.

    That's a thought! Did you have any distributor clearance probs or driveline vibration after dropping the t/case?

    That question has a different answer for almost every truck.
    No the slip yoke won't fall out.
    Vibrations.... try it and see. Some have em, some don't.
    Shaft length....should be fine. If you need a longer one, let me know. I had one made and only used it for 3 weeks. Then I went 1 ton, so it is just sitting.

    my 90k5 had a bad vibration at 40-55 mph after installing the 4 " lift.i shimed the rear avle 2 degrees and dropped the trans case half an inch,still had slight vibration.I called driveshaft solutions-they build double carden frt u-joint driveshaft-no problems at all after that
