Has nobody done this swap? Im interested in it being that its the middle ground between the 4.10 and the 4.56

You'll want to double check to make sure you can get 4.30's for the front diff. I know when I looked into swapping my gears a couple years ago no good companies were making 4.30 ring and pinions for the AAM 9.25" diff so I stuck with 4.56's.
I was able to find a complete Kit, front and back, with all the little goodies:

The issue it raises now, is the ring gear is a 11.8" which dodge started using on the max trailer optioned trucks (this is all information, which i learned off the internet, so take that for what its worth), but the Regular 2500/3500's have a 11.5" rear diff (which i believe i have)

Brandon, you run 37's, iirc? I agree with the choice to go with 4.56, But i plan on not going above a 35, so I think if the 4.30 is out, I'll do the 4.11.

Yeah you should still have the 11.5" rear end I believe. I think it's only the dually's that have the 11.8" from what I've read.
If you are sticking with 35's I'd honest recommend 4.10's at most. I do run 4.56's with 37's but honestly I find it to be geared a little low at times. It's great for in the city and when towing but on the highway I feel like I run out of "comfortable" rpm before I'd like to. If I had to do it over again I probably would have gone with 4.10's with the 37's.
I'd also recommend AAM or Yukon gears over Nitro. I've heard of a few guys having issues with the Nitro gears on the 4th gen Ram's.
For those I've come across more information. I was able to locate 4.30 front and rear gears, from AAM, and the front diff is reverse cut.

Awesome information! I hope you can reply to this older thread as I have been researching like crazy to get an educated answer to my questions.
I have a 2015 Ram 3500 single rear wheel with a 11.8 rear axle, so I'm told as per my VIN. I have the Aisin transmission. My truck is lifted 6" with the BDS 4 Link Long Arm Suspension. Running 37x13.50R20 tires with 20x10 rims. Weight of truck is 10,600 with my fuel tank and tools in bed.
I have been told several different gear sizes. So I'm asking for help with someone who has a truck like mine that can tell me what to get. 2 mechanics say 4.56, 1 says 4.10, and 2 say to run 4.30 gears.
When I calculate it out I get right near 4.30 gears to get my truck back to stock output of the 32" tires and 3.42 gears. I want to save my transmission and get the seat of the pants feel back that I had when leveled and running smaller tires. I drive mostly under 75 mph, tow some, and occasionally run 83 mph on the interstate for 250 miles at a time through MT. My truck is used in the oil field as a supervisor truck. So a lot of under 40 mph driving off road.
P.S. Ray at DRD said he would run
4.56 if I couldn't get the 4.30 gears. I definitely trust his opinion.
HOW MUCH FOR 4.30 OR 4.56 GEAR SWAP?

The only thing I can tell you is the AAM aftermarket gears are cut different than the OEM. They tend to howl until they break in. I used Justdiff several times and have done several of these rears. Good company, but GM rear parts. In fact, I think there's a thread about it from 3 years ago. Good luck
You'll need a dial indicator. If it has a shaft clamp, get a 6" bolt and turn it down to fit the shaft adaptor. Set for .005 back lash. It's the quietest.

That's what I was thinking. A single wheel 3500 should be around 8000lbs or so. I know my CC F350 dually was 8630lbs with me in it. I'm not that big of a guy
A 10k + pound truck is getting into the Kodiak, 5500, F550 series trucks. Our style trucks generally have heavy beds on them
As for the gearing so no issues and they're common. Just go with the 4.56
With 37's that's kind of an odd middle of the road range trying to get the best ratio. Personally I don't use them unless I go over 40" but that's generally in mud
