I have A 94 f350 I just finished lifting.

Front I went a total of 9 to 11 inch by sky manufacturing 5 inch reverse shackle and 4 to 6 inch leaf springs. ( not sure exact lift leaf springs where)

Rear I did 6 inch reverse shackle also from sky manufacturer.
how ever there is blocks here. Total of 6 inch, 2 blocks. Which I plan on swapping out with a single block from PMF with desired angle for dif to pinion.
So my questions are here with in this.
First let’s start with drive shaft. I was reading that some people get away from extending it by giving there dif a 5 degree angle. This sound some what crazy because I understand pinion angle and would like to know if this is doable.

I am all about doing this right, so I already know I have to extend my drive shaft and put some type of pinion angle. My question are where do I start, measure now for drive shaft or angle etc.

^2 I ran 1410 u-joints all around on my F250. I know it’s older but should work fine on yours. I went to jy and got driveshafts out of 95 Fsuperduty and made my own 1410 shafts

A 1350 only 20 degrees, a 1410 at 37 degrees of operating angle, plus stronger.
