cu in oz Ok, I'm getting to this very late but here goes. I have 3.21's in my 6spd. Sport "S". I bought in August!. BUT, it was the ONLY Sahara Tan Sport "S" Hardtop 6spd. ANYWHERE near me and I wanted the colour.

I didn't even consider the ramifications of the 3.73's, I wanted ONLY Sahara Tan.

IF......IF I had a choice I would have got 3.73's. Thats for sure. BUT.....I tow a 14 foot alu skiff with a 9.9 Yami 4 stroke (total weight maybe 750#'s with trailer and gear). I have zero issues towing. I live on the coast and the 3.21's are great. Also the performance for my use is good, ya, its best above 3000 rpm's but at 70 I'm only turning 1900! The gas milage is very very good considering its a 4wd brick......but its a great ride!

tcass had a 2007 6 speed manual with the 3:21 gears.....couldn't get out of its own way unless it was going downhil with a tail wind. forget uphill, you would have to go to at least 5th and sometimes 4th. i traded it for the 2012 Rubicon 4:10 six speed and love it. the combination of the penstar and the 4:10 rear makes it fun to drive. the mileage with the 3:21 sucked because it didn't have enough power to push my 33" nittos. Walk away from the 3:21...jmho

I already tried to place an order for an Arctic, but two different dealers said you can't custom order them. Limited run BS story. End of the year deals, can squeeze the dealer a little extra. And you are right, I'm not buying eiter one of them, as it turns out the cheaper one doesn't have A/C listed on the sticker. Who would buy a car without A/C???

Factory remote start? Mine works fine (press the button twice within 5 seconds to start). Runs 15 minutes max and:

Remote start will also cancel if any of the following occur:
• The engine stalls or RPM exceeds 2500
• Any engine warning lamps come on
• The hood is opened
• The hazard switch is pressed
• The transmission is moved out of PARK
• The brake pedal is pressed

I unlock the doors, get in, and put the ignition on. That's it.

New2012JEEP Let me know, that is good info to us. We normally head to Port Isabel, RGV area 3 to 4 times a year, all family still there. Hope can find some cool places to go wheelin when we get there.

Thanks. I do need to put some sort of rail on the side, more for the kids than for protection; they can barely get in!

On topic, I'm putting in a hitch next week. I'll pull a few loads to see how it performs and report back.

I probably should have held out for the 3.73s, but I needed transpo quickly and this met the majority of my specifications. when I hit 50K or so I'll probably end up doing a regear.

ETA: I LOVE Texas: 30 DEC and 76 degrees! Took these pics today.

Don't know what it would cost for your YJ, but you want a master overhaul kit, since they'll more than likely wreck the rear pinion bearing and maybe some other stuff during removal of your old gears.

Best to let a shop that does the install buy the parts for you, as well. That way, if anything gets screwed up (missing parts, bad parts, etc), it's on them and they'll take care of it. It'll also keep the manufacturer's warranty intact.

For a JK, a gear change costs about $1500.

Yeah, not a DIY mod unless you're very sophisticated.

This thread is in the JK section though, so the tech knowledge is going to be skewed to the 2007-current models. I'd check out the YJ section to get answers specific to your Jeep.

New2012JEEP Get either 3.21 or 3.73....still a wrangler at the end of the day. 1/10 mpg doesnt matter over a few 100.

Gas prices coming, will fluctuate by a ton more than that

You might as well buy a rubi with a 4.1 ratio and it comes with lockers. I just did a gear change on a 11 two door, and put a eaton elocker ($900) in the front. 3.73 to 4.88 ratio as I run stock tires and the jeep is auto. Also swapped the front and rear diff plates with some upgrades while I was at it. Didn't lock the rear as it had LSD from the factory. Cost me $3700 for the turn key job. Time you lock the rear you are real close to 5K. I built a new COD rubi on the jeep site yesterday. 2 door loaded up. List price $44,450 and some change. OMG that's high, but a better buy then that arctic sahara thing!

Well it works fine, just the step to drive off doesn't seem to work the way you put it. I put the key in and turn it to go, but I can't shift to Drive unless I turn the engine off first and restart it. Mechanical problem??

Thanks for pointing out how to turn it off remotely, didn't read the manual...lol
12-30-2011 09:15 PM
Wil Drove a '12 6 sp. with 3.21 gears and didn't like it. Very sluggish. It also had 17" rims too.

Just my cents, they didn't have a '12 auto at the time.

4x4Viking here are the stickers, the more expensive one is the one I like, but it's lacking the 3:73. The other one is the only one with 3:73 within reasonable distance, but lacking some useful things like towing package, air bags etc.

if it was a keyless ignition it would work, like the Mercedes push button start, but with a standard key...no, still have to stick it in and turn it and turn it back off then back on to restart the car...

For me, I found "almost" the one I want but it comes with 3.21 (which I didn't realize was an issue until I read this thread), and it doesn't come with Remote Start which seems very cool, especially on hot days.

I tried to explain earlier....it impacts how many RPM's you turn at an given speed.

Example:
At 65 mph in 5th gear and on stock wheels:
3.21's will turn 1815 rpm's
3.73's will turn 2109 rpm's

Now, the engine makes more power at 2100 rpm's than 1800 rpms, but it also uses a touch more fuel. You have to balance that with trying to find the "sweet spot" of the engine.


From what you have stated, you will want the 3.73's....it will have more pep, and will tow heavier loads easier.
12-30-2011 08:40 PM
ranjr Just drive one with 3.21 and then one with 3.73 and decide for yourself. Everyone on this site pushes for the lowest possible ratio available. I'm surprised nobody has tried to talk you into a Rubi yet just for the 4.10 ratio.

Only you can decide what meets your needs. But to me it sounds like the 3.21 will be fine.

Sorry holyjeeper...got you confused with the op. You got a buncha posts running loose at the moment.

You'll notice a difference in power between the 3.73 and the 3.21, mostly on the freeway. Hardly at all around town. IMO, Jeep shouldn't even offer the 3.21 gears. Your mileage will be MINIMALLY less with the 3.73's, and if you ever do decide to tow something you'll be glad to have them.

There are a lot of people on this forum (and others) who thought they'd be fine with the higher gearing, and then realized later on that it was inadequate for their needs. That's a $1500 mistake.

You can pick at it all you want...most of the folks in this thread have said, straight up, get the 3.73's.

But it's your Jeep. If you think you'll be better served with 3.21's, by all means...
