need help with driveshaft for bigger lift...

[Kartoon]

i have a 4" lift on my 90 suburban right now and in the future i would like to go up to a 6-8" lift. i think ive read on here that the most you can get away with the stock driveshafts is 5". are there companies that sell driveshafts already extended, or do i need to send mine out? what are good companies to use? and the most important question- how much should both drive shaft be extended. thanks for any help.

i had 6" in my 1ton with fixed yoke rear. and no problems with it. had flip kit in the rear also. some need them some dont after 4" of lift or more. longbeds tend to get away with 6" . front will need to be done tho.

That pic isn't too good. Are there any splines showing? I had my front extended 2" with a 5" lift. I really could have gotten away with 1", but I wanted the option to go bigger later.

watch that drive shaft being TOO long, if it runs out of compressiopn it can spell bad things for your t case.

You really need to measure what lengths you need at full droop and compression, and check your stock shaft to see if it will work. I wheeled the piss out of mine quite a few times and she never bound up on me. Like I said, 1" was good for me but I planned to lift it another 1-2" so I went with a 2", but I also had more travel in my slip yoke to accomodate it.

What tranny/transfer case do you have. I have the driveshafts for 8" lift. I had the sm465/np241

 

[Kartoon]

its in all stock 3/4 ton, 350 suburban. if thats the same for what you got, PM me.

 

[ratzila]

What kind of transmission/transfer case do you have. I had the sm465/np241.If you have the TH400/208 it won't work because the front driveshaft will be too short & the rear too long

well when i looked online, it seems that the sm465 is a manual transmission, and since mine is an auto id say they wont fit. thanks anyways.
