    I know a SYE would be best but if I can get a Double Cardan Rear Driveshaft made locally for a decent price, would it be sufficient with my NP241? I will have about 7" of lift in the rear.

    The lower shaft in this pic is what I am refering to

    Well, the problem is that with that kind of lift and such a short shaft you're putting the driveshaft at a steep angle. When the suspension compresses it's trying to slide that shaft in at a severe angle. It puts a lot of stress on that tailhousing.

    I haven't seen a broken 241 yet but I have seen a broken 208. It's kind of a kick in the teeth when you bust the back half of your transfer case off.

    If you had more wheelbase I wouldn't be worried about it. But I know that right now with a 2" longer than stock K5 driveshaft and my yokes near their limit at full droop you can see the pain the tailhousing goes through.

    i would think that being a cv at the tcase end of the driveshaft it should be okay... :confused:

    Think about it a little longer. The angle is actually STEEPER because of the CV part shortening the driveshaft. It is a lot of side load on the tailhousing.

    All the CV part does is alleviate the ANGLE of the UNIVERSAL JOINTS.
