drive shaft

[6.2L Jimmy]

Hi Everybody,

I have a question I am asking for a friend, on a 88 Blazer
with a 4-inch lift ,does the drive shaft have to be lengthened (700r-4 tranny) or will stock do?

Thanks,
Mike, for Gary

Should be ok. I ran 4 in lift w/stock drive shaft. I did the ORD shackle flip and zero rate blocks and still ran the stock shaft.
A little to much vibe so I got a CV shaft. The stock length should be ok.

I have 5 1/2'' on the rear with the stock shaft using a shackle flip and 1 1/2'' blocks. I lowered my T-case 1'' and my drive shaft doesn't vibrate anymore (nothing worth mentioning anyway)
