WTB Front 4x4 Driveshaft
 

Looking to buy a new front driveshaft for my 71/72 K20. Need one that the slipjoint is working properly and is not bent. Having good U-joints would be good too.

BTW, does anybody know if a 'stock' front driveshaft will allow for a 4" lift??

Thanks,

Hey 72 Longbed
If you can use a "used" front driveshaft, I have a few laying around. Takes time to do these things doesn't it.

I have a front shaft from a 72 blazer that had a 3 speed trans...It may be longer than the pickup one...If you could get me a measurement close,I will check mine...If it will work...$60 shipping included...Thanks,Erick

And my 69 K/20 had a 6 inch lift with stock shaft...worked fine...

GM72K10,
Hey Gerry, how ya' been? It's good to hear from you again. A used shaft is OK as long as the slipjoint is not siezed up and works in and out freely and the tube is straight. Send me a PM with your phone number and I'll call to set up a time to stop over.
BTW, do you have any of those transfer case boot rings that hold the rubber boot to the floor?

Thanks,

bisquik65,
thanks for the info on the shaft. If I can't find one local, I'll be back to you on that measurement.

Thanks,

From what I remember when I got mine all the front shafts were the same length between blazers and pickups (I have a 3-spd blazer). Of course the used one I bought is still in the box because I have not made it that far along in my Blazer's resurrection. I will see if I can't confirm it for you tomorrow.

I took a measurement yesterday of the front drive shaft distance and it is approxiametly 30.25" from back of U-joint cup at the transfer case to back of opposite U-joint cup at the Dana 44 (deepest length). Now here's the thing though :( ; the cab, front clip, and transmission are not in the frame right now so I don't know how much more the frame will settle down and if that will change the length dramatically. The frame has a new 4" Tough Country spring lift on it so the springs are pretty stiff right now. From what I have read on this Board, the 'slipjoint' should allow for some variation in ride height?? Yes or No??

Thanks,

I use a SJ 4'' lift on my 72 4x4, no problems with the front drive shaft. I don't recommend extreme four wheeling.

You have to worry more about the rear shaft, front one is cool! I have a bigger lifted 68, about 9" total, and the rear shaft looks to be a little short and not the front. 9 inches taller than my stock 68 4x4. The only bearing hard to swap is the little one in the center of the double joint. I just rebuilt my front shaft.
