Looking to regear my jeep and I'm debating on going to 4.56s in my current axles or putting in an HP 30 and going to 4.88s. I run 35s and am just trying to decide if having 4.88s is worth the couple hundred bucks more for a HP axle and the work of swapping them.
The Hp will be stronger. It all depends on how you are using the rig, how much money yuo are looking to spend, and what youre going to do with it. Personally I would spend the extra money up front and not regret it in the future.
Stronger even with the smaller pinion? I use the rig on the trail mainly and a lil around town. I never go down the highway and when I wheel its mainly in rocks and wooded off camber trails not much mud for me. I'm ok with spending the extra money but only if the performance benefit is worth it.
yes the 4.88's in the 30 are weaker the 4.56 becuz of the number of pinion teeth in contact with the ring gear. The hp is stronger then the lp but how much is uncertain. It also runs on the run side of the ring gear with hp rather then the coast side which helps. I posted this question last year and decided to sell it all and go with dana 44's. A quick search would have found you this thread or one just like it im sure.
If youre planning for a 60 in the future, run what you have now. I went down the same path last year building a 44 with intentions of building a 60 in the future and wish I would have just saved the money for the 60 initially. You can always spend the money you would be spending on gears now, for the 60. then when you do end up with the 60 you already have the parts to build it and not worry about buying the parts in the future.
I can't even buy a 60 for what regearing my axles will cost plus I'll have to build the 60 get all the brackets put on and get a 14 bolt in the rear to match. Will be an expensive and intensive swap. I'm just tired of being underpowered 3.73s on 35s is no fun on the street or at the dunes

I agree with the people sayin just run what u have. Just make due with what u have and save for what you want. Thats what I did. Yea my jeep wasnt that great for a couple years(shitty top, 3.73 gears, no lockers, bald 36's). But now it exactly how I wanted it and im very happy with it.

There is no helping this kid. I think that you should put 5.38 gears in your stock jeep axles. That would be super awesome. And I dont know why your current setup is no fun at the dunes. Thats what I had and low range 3rd gear was perfect. Nothing it couldnt do.
I have 5.13 with my 36's. For highway driving it isnt the best thing but not terrible but offroad its great. What was trying to say is its better to deal with it for now then keep spending money on things that are only slowing you to your end goal.
Good for crawling, but that's about it. Not good for dunes, mud, or snow wheeling where you are more likely to stay in high range, or you'll be in 4th and 5th gear in low range.
I'm ok with running a high gear in low at the dunes just thinking the 4:1 might be a good idea so I'm not putting money into axles that I'm gonna ditch in a few years. Just trying to figure out what makes the most sense motor, gears or tcase
You can swap the internals from a dodge 241 and you'll have a 6 gear planetary and a thicker chain. You just use the 231 input shaft i believe? Don't quote me though I'd have to find the write up to make sure
Yep. The difference in ratio between a rig 3.73s and 35s and one with 4.88 and 40s is not that different.
White Rhino runs 4.88s and 40s; but he did the right thing and put a V8 in there for his play time at the dunes and in the snow.
Since you want more power for driving around and at the dunes, I don't think a gear change or especially a Rubi case are the solution. You need more horsepower, plain and simple.
If you want an all around rig that crawls and creates wheel speed, you will not do it with a transfer case and axle gearing. You need hp. Therefore, you should bump your stroker thread.
I may rebuild my motor as is then regear or do a tcase. That or so a stroker just wondering if it was your rig and had a limited budget what you would do
He sure does have a lot of expensive ideas. What does a used rubi case go for now a days, im guessing for about as much as a good used 4.0 with low miles and more hp then he has now. No wonder everyone is starting to call you out on them. Pick one thing save up, do it and move on to the next.
