To run 37's your gonna need 5.13's with a stick or 5.38's with an auto.
Just be sure with that front 44 you sleeve and gusset it. The 37s will put a stock housing thru the ringer.
If you are getting the factory Rubi D44 up front, you're still going to need to add c-gussets, sleeves, beef up the control arm mounts, etc. The housing is prone to bending on these JK axles. Plus, you'd want 5.38s with 37s, not 4.10s.
I dont like these "absolute" statements...
I'm on 5.13 with my auto and it got more power to the wheels than with the stock 4.10 on 32"... And they're stronger than the 5.38.
We're speaking of making it solid, then 5.13 are more solid than 5.38...
"you're still going to need to"...
Not eberybody needs gussets and sleeves and what not to wheel...
OP sais he does "moderate abuse"...
This in my book is Dana44 stuff.
No need for D60, or everything everybody says you need.
Yes gussets and sleeves are nice.
Just as CV joints are nice.
"Do you really need them"...? Probably not.
Good advise from everybody but nothing is absolute.
It's a matter of choice and decision after a good evaluation of your needs.
Always a principle of compromise. And $$.
