So, I just acquired a 1990 Chevy Suburban 1500 4X4.

I want to lift it eventually, But have a few question that maybe you guys could answer.

I am going with a 6" lift, with 35 or 36" tires. Will I need to do anything to the Drive shaft, or transfer case, as in Lowering the case, or extending the drive shaft?
I have read things here and there, but I have not been able to get a definite answer.

The kit I will be going with will most likey be SkyJacker 6" kit with Dual stabalizer and 52-Inch Replacement Rear Springs instead of blocks.

Thanks for any help.
