8.5" Skyjacker question

[06TWO50Diesel]

I'm about 85% positive I'm going to go with this kit. 4-link front end conversion, the bells and whistles, for a pretty good price. The comparable system from Rize was closer to $4000 and that's a bit much.

My question lies in- Drive shaft. Will I need a longer drive shaft, or will it come with the necessary parts to "extend" it either way? I'm getting excited to lift the truck for the summer so when summer comes it'll be a "high roller" with the big dogs!!!

I'm not sure but I would think with an 8.5" lift you would need to have the driveshaft(s) lengthend.

I'd use the pythagorem therom and figure it out. You know the distance from the TC to the front of the truck (A) and distance from the front of the truck down to the axle (B).

A(A)+B(B)=C(C)

Squareroot of C(C) = C.

C = lenth of driveshaft needed.

Lets do a sample problem. A = 2 B = 4 C = ? so we'll just use C as the variable.

2(2) + 4(4) = C(C)
4 + 16 = C(C)
20 = C(C)
Sqroot of 20 = C
Roughly 4.5 = C
Now apply whichever units you were working in.

Of course this works on paper but probably won't lol...

hahah thanks for the math class marty! i was asking because i know on the older SDs you had to lengthen it (or simply buy a new one). I didn't know if changes were made to either the truck or the new lifts that took out this factor, which would make life a bit easier as well.


thanks so far!

i had a fabtech 8" kit on my F350 a few years ago and didnt need any lengthening done.
