Dana 44 R/P strength question

I have read numerous threads about upgrading the Dana 44 axlehousings with gussets, trusses, sleeves,and going with chromoly axle shafts to be confident to run larger tires. I realize doing these things makes the axlehousing and shafts stronger.

My concern is the strength of the ring and pinion. I feel that a that a 5.38 R/P ratio in a Dana 44 is the route I would like to go to run 37" tires.

Would a 5.38 R/P in a Dana 44 hold up to a 40" tire with if I'm careful on the skinny pedal?

Maybe I worded my question poorly. Should I be concerned running a Dana 44 ring and pinion ration of 5.38 with 37-inch tires? 40-inch tires?

I'm getting ready to do the Exact same thing on my D44's...with 40's... The gear set is all I'm worried about...going to 5.38's has me a little worried..but I'll get more opinions before then.

Who do you plan on getting opinions from? I was hoping some one here with experience would chime in.

Depending front or rear, makes a big difference. We took out my rear 4.10 ring & pinion and compared it to a D60 4.10 r&p, not much difference! I went with 4.88s though to make sure I kept the pinion strength.

I ton of guys have been running 37s on 5.13s and 5.38s without problems.

Me, Co4Lo, and White Widow (and probably more) have been running 40s on 5.13s without problems.

From my readings on this and 2 other forums.

With a properly installed gearset and an axle housing with gussets/sleeves/truss so it won't flex, the gearset and pinion will not be the weak link.

If the steering is turned and hammered, the u-joint will be the weak link.

Otherwise, the chromoly shaft will be the weak link--with the steering closer to straight.

If the Rubi locker is trying to engage while you are bound up, it will be the weak link. If you lock the locker prior to the obstacle, the Rubi locker will not be the weak link.
