Axle Swap Help!!!!

[t89blazer]

I just bought a CUCV and am planning on doing an axle swap on my 89 K5 . Currently I have a 700R4, 241 and 10 bolts. I have a Rancho 4inch lift with 35 inch tires. My question is will I have to lenghten or shorten my driveshafts? I have stock shafts front and rear with a slip yoke in the rear. I think I read somewhere that the longer pinion on the D60 and 14 bolt will make up for the lift and basically move the shafts back where they need to be (give or take). I am planning on having new shafts made, but I only want to do it once. I am in the process of building a doubler, but would really like to install my new axles now if possible.

Thanks for the help,
Tim

I have a 700 with 208 and I still run my stock shafts after I removed my 10 bolts and installed a 60/14FF combo.

Do you have any fears of the rear shaft bottoming out and breaking the tailhousing of your tcase? Thanks for the quick reply.

Nope I have wheeled it and had no damage at all. I also dont jump it either .

I got no damage from doing this.


The front is compressed as far as the axle will go and the rear is dropped out as far as it will go.

Yep, me 2 times. First with my 89 then my 90. I am still running the stock front shaft on my 90 now.

i got a custom lenghtened shaft made for my 6" lift going to my 10 bolt front. it was too long when i swapped my D60 in. 700/208 combo

the pinions on 60 and 14 are longer so with lift they fit perfect.
