Another driveshaft question... 1979 Suburban 6" lift

[SuburbanGuy]

I apologize if this seems redundant, but I did a search and could not find the same situation mentioned.

I have a 1979 Chevrolet Suburban with a 4" lift with rear blocks. I'm going to a 6" lift with rear springs. My driveshafts are fine with the 4" lift and my u-joints are good.

Does anyone out there have the 6" setup on their older Suburban? Any problems with driveshafts being too short or angles too steep? U-joints? It is a Rough Country kit, and I don't know if the kit has an angled shim on the rear spring pack or not, or if it would be necessary to shim at all.

Thanks for your time, and I apologize for the Noob question.

With your long wheelbase you should be ok driveshaft wise.
As for that kit, I hope you are not looking for a sift ride. I have there front springs and they ride like a tractor. Just a word of warning.

same w.b. as long bed truck. i had 6" in my old one. with 1 tons and 4" flip in back and 2 " block to level out rear. was fine no problems. frt was a tad grindy at times with flex. but i had no sway bar also more flex. rear was fixed yoke transfer. slip shaft might be close.

Thanks for the input, guys. I appreciate your responses.

I'm hoping my 35's will absorb some of the shock!

On the same note, the vent tubes for the front and rear diffs are very taut. Have you guys ever had to lengthen them?

Anyone know what OD/ID tubing that is and where to find it and the connector to lengthen them?

just regular fuel /vent line hose. easy fix.
