5.13s have been ordered and hopefully will get installed next week. Can't wait!

The 2020 Gas Hd”s have the 8 speed, and I don’t think it would need a re gear from all the positive posts we see. But only an owner could make that call, go drive one and see what you think.
But if he is going with 37" tires, he will still want a regear most likely. Taller tires will still reduce the overall ratio and cause the same types of issues as the 6 speed trucks.
Awesome! Glad you like them so far. I go next week for my 4.88s and hope to be content as well. He wasnt sure about the carrier when we last spoke, but he had it all written down in the file where he quoted me. So if so it should ha e already been shown in my price. At least I hope!
Keep us updated on your thoughts as you continue driving it.
I will be interested in hearing if yours needed it or not. I was charged about another $500 in parts & labor!

i was looking at a site just yesterday and i swear it said these axles had no carrier break so im not sure why the carrier needed changed. what brand gears are they? maybe call the gear company and they likely could shed some light on it. the carrier change may eliminate the need for a ring gear spacer and thats why they swapped it
I can’t wait to hear how you like itI drop mine off tomorrow evening so they can start Wednesday hopefully. If not he said thursday. Mine will be Yukon I assume in 4.88s.
I was wanting Yukon on the front & AAM in the rear cause I heard the AAM were more quiet. They talked me into Yukon front & back. Said if installed correctly that these would be just as quiet as the factory AAM's.

Thats because they are cut exactly the same as the AAM. From what I understand, they're practically interchangable, and Yukon markets these sets as "AAM Cut".
Well I know that this is the Power Wagon forum and I have a 1500 with 37s and 4.88s that just got re geared a month ago and SOB am I loving it, holds 8th on the highway all the time and even up hills without down shifting, so you guys should definitely be happy with 4.88s for your Power Wagons.
I went with Revolution Gears and SOB they are quiet, they really did a great job ...

So far I love it. I haven't towed anything really of weight, but man the everyday driving is awesome now. As everyone has said, just so much smoother and effortless driving over stock. The 4.88 is not even close to overkill. They feel almost perfect to me.
Use a calculator, no guessing required.
Select the 68 RFE in the drop-down menu for your transmission. It’s the same exact gear ratios as our 66 RFE
Then all you have to do is put in your desired gear ratio and tire size and then you can mess with the calculations at the bottom and see your exact speed and rpm.
Add about 50-75 rpm for wind resistance

I have 4.88’s and I’m running 35s. I kinda wish I went to 5.13’s.
IMO
33”tires need 4.56
34”tires need 4.88
35” or large need 5.13
Again... JMO
My next set of tires I’m going to go a tiny bit shorter but a little wider. I’d like to get a tad more RPM.
