What bj's does currie use?
Have you visited the Grimm Jeeper gear calculator? While 5.38's are the better choice it's up to you if the small difference is worth it.
My opinion is to stick with the Dana 30 and use the money saved to add a big brake kit to your build.
I just finished putting 5.13's in a HP Dana 30 for my LJ with plans for 35's. I thought about a Dana 44 but the Rubi axle wasn't a big enough upgrade and a Currie was overkill for my needs. Here's a screenshot of the difference between 5.13's (left) and 5.38's (right) with 35's.

Here's my plan:
'04 LJ non-Rubi (LP30 and 44 rear)
What front axle would everyone recommend I go with?
I see 3 options:
Rubi LP44 w/5.38s
Currie 44 w/5.38s
HP30 is obviously the cheapest/easiest swap. But this is my daily driver, so I think I would want all the gear I can get with my 42RLE.
I would love a Currie 44 for the 5.38s, HP, and increased strength, but dang that price stings.
I think it boils down to how big of a difference 5.38s would make over 5.13s in daily driving, and whether the increased strength of the Currie is worth it. Let me know what you guys think, any input is appreciated!
My LJ has 5.13's and a Rockjock 44 because I didn't add the new axles at the same time and I had a rear 44 with 5.13's. I don't mind the 42RLE, I also live in the midwest so it's pretty flat here. 5.38's are the best choice but the 44 is not so you have to pick your poison.
I'd go with a 30 of either flavor and build it. Then when you decide you want 37's or larger get 60's.
Hp30s are cheap and plentiful. If 5.13s are your gear choice, then that is the route I would go.
Allows for less pinion angle and a tummy tuck while maintaining castor, if you get the knuckles from an 86 Cherokee they also allow for a bbk if you use explorer rotors and the 1500 ram dual piston calipers…

Thank you all for the input. Strongly leaning towards avoiding the Currie44 and going Rubi44 for the 5.38s.
This is my daily after all, and I’ve had poor experience with being undergeared in other brand of 4x4 (roughly the equivalent of running 35s on 3.07s on a TJ ), so I want all the gear I can get!
