Is the 8.8 in the back of the truck the same as the
IFS 8.8..

I think they use dif install kits but the gears are the same ??
And how high of a gear can you go in the 8.8 I have 4.56 in the
rear and havent done the front yet but if i can go higher then 4.56
in the front them im going to go higher in both.


Like if you look up the rear 8.8 you can run like 5.+ but in the front
I have only seen 4.56.

 

The gears in the front are a reverse cut. You can't put a set of gears from the rear in.

If the 4.56 is as deep as they sell for the front, then you're stuck with that.

the front is reverse cut. if you install regular gears they will starve of oil.

 

actually, they won't even fit in the case.

 

Can't starve them if they don't fit....

well that sucks if you cant go higher then 4.56.......

Because ill be running 37in tires in like 4 months and i want to gear up to like
5+ because i like 4.56's with 35's and i dont want to lose power

 

I am running 4.56's in mine with 36in Mickey's and have plenty of power. You should still be fine with the 37's and still plenty of power and be able to drive at highway speeds without running to high of RPM's
