4.56 vs 4.10 (d30/8.25) 97XJ

[What Rd]

If you want to stop by some time we can swap your 31's on to my rig and you can take it for a ride to see firsthand how you like the combo.

Kudos - this is by far the best thing to come out of this entire gawdaweful thread. This offer must be accepted because you'll never get any better idea how YOU will like a particular combination (especially when MORONS keep opining based on what they "think" or have "read" or "heard" or know from "some others" . . .

Please try to ignore people (like virginxj) who are trying to tell you what they know because they looked at a chart on the internet. Think about it. Here's a guy running stock gears who's telling you what certain specific lower gears will do to your driving experience. Isn't that just a bit like relying on a virgin to tell you what certain specific sex acts will do to your $*@#ing experience?

good luck

yes you want at least 4.56s w/33s 4.10s wont cut it. i even wish i had deeper gears(4.88s if the 8.25 would allow it) w/my 33s but the 4.56s are good enough. run down:4.56s and 31s still very much road friendly and great offroad, 4.56s and 33s nearly perfect onroad and still great offroad. if you think you might ever go bigger, do the 4.56s now and save yourself the cost of regearing twice.

I agree, 33's, you need more than 4.10, 4.56's are the max so... with 31's and 4.56's you'll be going 5-7 mph slower in 4th gear at any givin rpm or at 55mph 270-350 rpms higher than 4.10's, but 33's will be nicely matched.

On a different note I have heard some say that 33's are to big for the d30 and you will likely break parts if you wheel alot, I am curious how long everyone has had 33's and how the driveline is holding up.

DUH! frequent downshifting is a cause of bad fuel economy.

What? ummm........I think the taller gear will give you higher RPMs.
Double Down, The overdrive will be just fine on highway with 31s and 4.56s. Don't worry about high RPMs.

who said frequent downshifting....

did I misuse the word taller:
numerically lower gears = lower rpms, numerically higher gears = higher rpms

too funny

virgin there is an axle tech thread here written by crash, read it to find out about what is good on what axles.

....and now ramsey thinks I should go read what crash thinks.
I've read those charts and talked to people who did 31's etc.
BTW it's not the only jeep i've been in or around, so quit assuming I am an idiot Im not the one saying people who run 4.10 and 31's are morons. I am the one who responded to you for saying it though, maybe that's why your panties are all bunched up right now. Respond to this however you want this is getting out of hand and a bit childish (both of us), so I wont respond to it since it has gone beyond modified tech.

 

[Ramsey]

whos panties are bunched? i stood by what i said and then supported it. there is some good tech in that axle thread though. i guess you need to chill, its just the f@wking internet man, dont let it get to you. i just wanted the guy to be properly informed. :cheers:

edit: Lest anyone get confused, this is addressed only to virginxj.

My panties ride in a properly geared rig and they feel fine!

You really don't get it, do you? If you actually had any relevant personal experience and disagreed with me, I could respect that. The only thing you've contributed, however, is to regurgitate what you've read or heard from others. Thanx, but from now on you should assume that those of us using this website have mastered the basics of reading for ourselves.

It was my impression that Chris posted his question because he was seeking advice and feedback from people with experience - people who had something in their personal experience that qualifies them to offer an opinion or advice. You simply don't know what you're talking about - and that is NOT helpful.

 

[What Rd]

. . . so I wont respond to it since it has gone beyond modified tech.

At least you recognize the subject of the forum. It's "modified tech", not "unsubstantiated opinions on tech with which I have no experience."
:bs:

 

[virginxj]

You guys keep assuming I have no experience, and that I base everything on the internet, if you are ok with that than well ok. The guy started out talking about 31's, that is what I have experience with. Everyone I know runs 31's and 4.10's the ones who have 4.56's say their rpms sit a little to high on the freeway. If you disagree then ok thats why we are here.
By the way What Rd you dont need to own every combination to know how it works if you have been out with people who do run it. Chris asked what gears are perfect for 31's and I told him what I thought and why, whereas Ramsey who seems knowledgables only said that lower is better and I disagree with that for someone who is 80% street. Although I learn alot from these sites I do not learn everything from them.

Ramsey I have heard more conservative "max tire size with locker" estimates form several people, and that is what I base my opinion on, I read crashes post and found it quite interesting, he however has seen and broken many shafts on d30, so I tend to favor a higher gear and a smaller tire to avoid this. If you give think this is bs then please elaborate, because many seem to share the same opinions. BTW Ramsey thanks for responding politely for the final post, I took your advice and went and chilled out before responding to this new reply.

glad to hear you've calmed down. one problem with gearing too high(lower numerically) is that you tend to need momentum to get up some things you could just crawl up if you had lower gears, momentum breaks things. i am pretty hard on my dana 30 locked running 33s and have only broken a hub, which might have been more wear than anything. a guy in my club up until recently was running 35s on his 30 with little problems, and he scares me the way he drives. some people get lucky others dont. general rule of thumb for a dana 30 is locked w/33s is the max, and that is with 297/760 joints btw. i think this subject and thread has been beat to death plenty hasta

[virginxj]

yes new to this site especially.

I should have posted a resume

that is interesting about the guy with 35's and rough driving, sounds atypical so hey lucky him, I wish I could remember the website that recommended the max tire sizes so you could at least see where I'm coming from. Sounds to me like you are doing ok with 33's best of luck to you. I am going to be sticking with 31's at least until they are dead, then who knows.

happy wheelin!

 

[Double Down]

Well, aside from all the "who knows the most" stuff going on, I appreciate the responses. I am going to try to get a hold of the local guy to test out the 4.56's, but more than likely I am going with those.

Lucky enough, I just bought a no-slip for the back and lock-rite for the front from a guy on this website a day after you all answered my questions, so it must be for a reason

Now, as soon as I can marry this girl I'm engaged to, the sooner we can use her car for everything and that 20% can become more like 50%+.

Best,

Chris
