37s on a 44?

Thinking about running a D44 rear (Waggy) with 30 spline alloys and Detroit, but not sure if it will hold up to 37s.

Might step up to 33 spline shafts, but like the 30s for ease of replacing with a junkyard spare if needed.

Still running a 258, but that will probably change to a mild V8.

I don't hit the go peddle too hard, but will if needed (Southeast trails) .

What's the general opinion?

It'll hold fine until you throw the v8 in there.

Well i have a friend with 36s and a 360 and its holding just fine. Note: The axle is stock but for the spool and 4.56s. Just a side note going to tall makes steep hills and rocks hard to work with. I have seen things that someone with 39s could not do but a guy with 35s walked up...

Thanks for the replies.

In my mind I was thinking it would be borderline and since I drive most of the time to the trails breakage is not good.

I run a 44 front with 36s and a chevy 4.3 with 4 to 1 and 4.56's I have only killed 1 shaft. I did some out of control stuff before it let go. Note: That shaft was from 1979! I now have crom shafts and that will be the end of that prob. I have a friend that runs a 44 front with 36s and crom shafts a Chevy 350 Klun-V for super low range and has been to Moab and back and has not popped the 44 yet.

I'm actually running a 44 front on 35's and haven't had any problems

The rear is a different story, its a FSJ 20 with a twisted tube and a Lockright on the way out.

I know the 44 rear would be more of a horizontal move, but it does seem to have more support in the aftermarket (alloys 30/33 spline).

I'm also looking in to 8.8" and 9" axles, but would have to do something about the lug pattern changes.

chromoly 35 spline shafts are available for the d-44. thats pretty beefy. I am not a fan of the "don't upgrade it becuase something else will break" theory.
I like the build stout crap and don't drive like an idiot theory.

I run 35 splin ARB and shafts in my rear 44, 30 spline chromoly shafts in the front and I'm going to run 39's

It's not what you have. It's what you do with what you have
