where can i find 4.10's
 
I am going to eventually upgrade my gears as soon as I get my tires and stuff taken care of.
I cant seem to find anyone who sell's 4.10's though. 4.88 is the smallest I can find. and I think that will be a little to tall for 33's.
I currently have 3.21's

Mopar/dealer ?

So umm, I don't wanna seem like an idiot, but 3.21, is that supposed to be the rear axle ratio?
I have no idea how this works, was hoping I could learn a couple things :)
(I have a 3.21 axle ratio, if that's what you are talking about... exactly what is that?)

Might try craigslist or ebay, probably a lot of people replacing the gears as soon as they buy the Jeep, so might be some new takeoffs

I know they make the rear's, but as far as I know mopar only makes the front for the D44 and not the D30. I might be way wrong though.

Yes 3.21 is the axle ratio.

and I have looked on CL but again. only the rubi takeoff's are what I can find and that wont work because of the D44 front.

Both your axles are geared the same.

I think Dana makes the Mopar gears.

I would think 4.10's would be easy to find though. You having a shop do them
Right, I hope?

Yeah I'll have a shop do them when I get ready. Gotta keep that warranty:thumb:

"That warranty" only applies to the gears installed by the shop and maybe not even that if you didn't buy the full kits from them. Your Chrysler warranty does not cover anything on the new gears nor will it cover any damage resulting from there use in your jeep or done by the installer.

You don't wanna buy the gears, anyway, unless you're accomplished enough to install them yourself, and even then it would be risky.

You should have the shop that's gonna do the gear change buy them...that way, you'll be covered by both the gear mfr's and the shop's warranty.

Order master kits for both axles, in case the mechanic trashes something during removal of your original gears (very common for the pinion nut to get trashed).

Find a shop that's done a lot of 4x4 gear changes. For parts and install, it should run you +/– $1500. The Jeep dealer is usually not a good bet.

Driveshaft will turn 3.21 revolutions per 1 revolution of the axle.

So do you need 4.10's or is that what somebody told you that you need? Cause honestly, if you don't need them, why waste your money?

I think he needs 5.38's :D

Ah Ef it..... Drop in D-60's and go lower.
Have a spare set of tires on hand :)

ShaunWV 04-04-2012 10:20 PM

I agree, 4.10's are a waste. I run 5.13's with 33's with my 3.8 auto, and it is right on.

Ah, glad I came back and looked at this again...last post was from my phone, surrounded by a bunch of boozers.

Let me see if I've got this straight: You've got a 3.6L, you're gonna run 33" tires, and you wanna spend +/ $1500 to go from 3.21 gears to 4.10's?

If that's the case, you're wasting your $$. First off, I'm running 3.73's in my rig with 35" tires and a crapload of extra weight from bumpers, armor, etc, and my power is just BARELY inadequate in 6th gear. For 33's and 3.21 gears, you're not gonna see much change from the stock 32" tires, especially if you're going with smaller rims than stock.

Second, I'm not even sure you'll be able to find 4.10 gears for the JK other than thru Mopar, who will fleece you like a blind man at the currency exchange for parts, not to mention the install, which you'll probably have to have done at the dealership. I wouldn't be surprised if it cost well in excess of $2K to have them do it. I'm really not sure about this part...haven't heard of too many peeps wanting to go from 3.21 to 4.10, quite frankly.

Here's my advice: Before you blow a pile of $$ on gears, install your lift, tires, wheels, etc and drive the Jeep like that for awhile. I'm pretty sure you won't feel the need to regear afterwards. Unless you move to the Alps. :D

Is it possible that you might, at some point in the future, decide to run 35" tires? If so, save the regearing for then. That way, you'll at least be able to go to an acceptable aftermarket gearset that is readily available and can be installed by a reputable gear shop.

That's my thinking on it, anyway. In the end, it's your $$. :thumb:

js16301 04-04-2012 10:34 PM

I have a 2012 JKU auto with 33's and I regeared from 3.21 to 4:10's. I feel the gearing is perfectI purchase from these guys. http://www.justdifferentials.com/ind...=22_35_116_464

Way cheaper then the dealer and were the only ones that offered Dana spicer ring an pinion in 4.10 that I could find.

Jim

js16301 04-04-2012 10:39 PM

By the way, if you wanted 4.56, 4.88 or 5.13, those are also available through them.

Jim

Preston777 04-04-2012 10:55 PM

Thanks for all the input guys, I might just take your advice and wait to regear until 35's. that or just put the gears at the very bottom of the mod list

Don't get me wrong...I'm not knocking you. But when I had a chance to read through this thread on my computer I was kinda surprised to realize you were talking about going only 2 gears lower, and from 3.21 to 4.10 on a '12, to boot.

Do what you think will best suit your build. I just threw out my advice for consideration. :thumb:

Preston777 04-05-2012 09:39 AM

No I like getting the input from others that's why I post this stuff up. Guess when I actually think about it more it does make sense to just wait for when I move to 35s.

appleman46 04-05-2012 05:14 PM

Would you say re-gearing is more of an issue for manuals as opposed to automatics? I would like 35" tires but don't want to regear and I drive an auto. With a 2.5" lift, do you feel like I need to regear? Keep in mind, I don't do any offroading.

Lift has nothing to do with regearing.. Tire size does.. In regards to 35's With the 07-11 you will loose noticeable power with the manual and it will be a total dog if you got the 42rle auto that was used in those years.. With the 2012 to be comfortably running 35's auto or manual 3.73's will be tollerable but 4.10's are ideal

It's actually LESS of an issue. With a manual, you control your shift points. But an auto, especially if you wanna use the OD feature, shifts itself. You can limit the high gear in an auto by turning off the OD, but even in the lower gears, WHEN it shifts is not in your control.

For the Wrangler, gearing is all about tire size, weight and rolling resistance. The height of your lift has a minimal effect on the equation (though it does cost you mpg's).

What year is your Jeep and what gears do you have?

appleman46 04-05-2012 05:27 PM

rgr that! thanks! I'll just stay with my 33's. lol


It's a 2011, I'm actually not sure about the gears........I'm not even in the country to find out, any way of finding out? lol...I'm not savy when it comes to vehicles.

Neither am I or at least I don't thinks so.. But I like to read and learn about subjects I like.. One of them being Jeeps/offroading.. I learned and if you want to hang around here long enough and you will to :)

If you ever want to find out your gearing.. There is a email contact on Jeep.com that you can put in your vin and some info and put request a build sheet in reason for email/comment box.. Then they will send you a buid sheet with all your jeeps stock info including gearing

appleman46 04-05-2012 05:36 PM

Would it be on the sheet that's taped in the windows at the dealers? I still have that sitting around, I can have the Mrs. round it up.

XJ Knight 04-05-2012 05:40 PM

I expect it should be..

appleman46 04-05-2012 05:52 PM

Rear axle ratio is 3.73. Is that what it would be? 3.73?
