Question so if I would regear and get strong axel shafts I would drop my percentages on breaking anything while wheeling? I would love to make a trip like the one you did in Colorado. Seriously I'm fascinated!
No problem. And yes upgrading axle shafts is a good start. As for the re gear, the higher you go the more chance you have of breaking the gears on the trail. Ive done my research and asking around. They all say no higher than 4.88. Due to the smaller housing, the gears become weaker the higher you go since the R&P are smaller (smaller teeth).

Im sticking with my 3.73s and not throwing any money into my d30 till I can get an aftermarket axle.

With that being said I would reinforce my c gusset and put all the other money towards a prorock 44 or similar aftermarket.

Alright I'll consider this for sure, I will defiantly be saving money for a aftermarket 44 but for now I can't get one unfortunately lol. Thanks for the advice. I'm trying to be as cost efficient as possible. I know it's unlike the "jeep" just emptied every pocket mentality but I'm always on a budget being a college student

37s on a Dana 30 here with 5.13 gears , sleeved and gussets no issues so far

You also got to remember to keep a weak point for me it is my stock axle shafts easy to replace and cheap , I rather lose a shaft instead of gears

Which is why I was looking at 44s but people say it's the same housing with different gears. With that being said I don't want to spend $2,000 (asking price on this forum) for a used/bet up with 20-30k miles on it just because it has $600 or less on upgrades. So I was leaning more to find out what upgrades I could do to the axel I already have to make it reliable enough to run 37s. For the Nitro do I need to take out the gears? Or just hammer it in after taking the wheels,breaks, and axel components?
Nope, same steps as replacing an axle shaft. Pull the wheels, rotors, axle shaft. Do the appropriate prep (I have a write-up on here from when I did it) and hammer them in. All in, it took me 4-5 hours and $150 (additional materials such as dry ice, etc.).

There's a pole on another forum of who's damaged a D30. 100 responses, 15% failed. Failures occurred on 33", 35", and 37" tires. As you go through the thread and see whose didn't fail, you'll see a common theme of sleeves, gussets, trusses, ball joints, etc. Yes, there are a few with nothing done.

In the end, I agree with what people are saying: save up for a better axle. However, you have to live within your budget and timeline and only you know what that is. There's a good thread in another forum that provides the actual strength increase from sleeves or a truss. Yes, not a Prorock, but it it approaches 75% stronger than stock. That's a huge difference. A standard Prorock is something like 110% stronger than stock. The numbers support it. The ring and pinion is another story. However, I agree that investing in more than sleeves and gussets isn't worth it on a D30.

You need $5k for a prorock. $2k for an unbuilt 44. Risking it works if you can afford to lose your daily driver for a period of time and have at least $700 laying around to buy a used D30 if you damage yours.

You're a young guy who likely has limited resources. Sleeves for $150 installed and gussets for $60 (plus getting a buddy to weld them in). No brainer in my mind. When I put my 37s on, I realized just how much beef you're trying to turn.

I have Chromo shafts, lockers, and 4.56 gears in my D30 and D44 with 37" Iroks .... you know it's a time bomb, but i've been driving it easy and so far it's held up OK

Great points, I think I may do gussets for sure now. I'll think about doing the sleeves also. I'll probably go ahead and buy them. Any suggestion? How much should I expect for install. I don't know anyone who welds in my area unfortunately.

The Nitro sleeves don't require welding. Just have a buddy help and follow one of the write-ups.

As for gussets, call around to some off-road shops. Also, look for local Jeep groups. Join and meet some people. Eventually, you'll likely find someone who will weld them up for you.

Alright thanks! Great help. I'll look into it for sure. Any suggestion on which gussets are best?
