I have been wondering the same thing. I know you CAN because I just test drove an 80 Blazer with a 6" Superlift and factory shafts. That said it did seem to have a bit of vibration. And what about off road?

i did it in my 84, but i used blocks in the back
I have some rear 5.5" SkyJacker springs that have the hole drilled about an inch forward of the normal spot, so no driveshaft mods were necessary on a K5. It really depends on the vehicle; almost all are different.

Why would it differ from blazer to blazer?

I have an 86 chevy longbed and a few years ago I put a 6in. lift on it. I installed 6 in. skyjackers in the front and 5.5in. blocks in the rear..the rear shaft was fine, the front shaft worked but I had it lengenthened a little anyways because offroad it would come apart. Hope that helps.

i wondered that too....but some people have problems and some don't
I don't know for sure, but that's why you get conflicting answers when you search. Some trucks need longer shafts and others don't, especially with 6" lifts, it's real borderline. The transmission/t-case combo can affect this also because they are different lengths. And the way the spring is manufactured will vary between brands.fireplug said:
ah ok i gotcha... well 700r and 208... dont know if anyone knows if this is one of the longer ones? its just a big deal cuz thats an extra lotta money he doesnt have to lift his truck.. as well as mine pretty soon..

I have a six inch spring lift with 35's and I have had no problem at all. No vibes, no breakage. D44, 14ff, 350, sm465, np208 and stock shafts.

another thing to remember is that if your truck is converted to 3/4ton the 14 bolt will make up some driveshaft length because of the longer pinion. not much but every little bit helps

I did 6" skyjacker springs front and rear on my 91 K5.
Had to drop the transfer case and put angled spacers under the front n rear springs. Other than that every thing fit fine with no mods to shafts

They may work for street use, but if you flex the suspension, they more than likely be to short.
