Which would u choose for a Mall Crawler: 3.73 or LSD?

I've been trying to find a 2013 JKU automatic transmission with the 3.73 and the Anti-Spin Differential along with a bunch of other options. But there's just nothing out there with what I'm looking for. I know the answer is to order a 2014 but I can't wait that long. However, if I eliminate either the 3.73 or LSD, that opens things up. So, I'm wondering which one you think is more important?

It's strictly going to be a mall crawler and taxi for the kids. Most likely will never go off-road or touch the OEM wheels/tires/suspension. I've read all the 3.73 vs. 3.21 threads and it seems like I'll get better performance from the 3.73. But, I'd really like to have the LSD for safety in bad weather. I'm in DC so we typically don't get a lot of snow but things can get slick around here at times.

What do you all think? Should I go for the 3.73 or LSD?

3.73. LSD isn't going to make your vehicle any safer. If your not going to go off road there isn't much use for it. The 4wd should help if you ever get stuck in the snow. I live in RI and been driving a 2wd frontier without LSD for three winters and never had any problems. Just less fun to get sideways without the LSD.

if you really don't plan on doing any modifcations or off roading. maybe you should save the extra couple bucks and just get a sport with the 3.21 rear ratio.

As much info as i've taken in from this site as well as another thread you made about a few weeks ago. i would say the LSD would come in handy especially with the slippery roads and other weather conditions. i believe the 3.73 rear ratio is better to have if you plan on doing bigger tires/wheels and or doing off roading.

the only problem i see you might have unless that just around my area. not too many wranglers on the lots seem to have one or the other. its usually they have both on them or neither...

The ESP will allow you to drive in snow in 2wd comfortably. Go for the 3.73

you really need neither....but the lsd will do you the most good....3.73 will just lower your mpg by 1 to 2 mpg.....

LSD seems to work really well in the snow in 2WD for me (here in Minnesota). 3.73 seems to do the trick for nice snappy acceleration. Everyone has an opinions - get whichever ones make you happy. I never hear of anyone driving around all pissed off because they went with 3.73 over 3.21 and mad because they bought a LSD. Cheaping out on something you want will cost you more in regret than you will save in money. Then again, some people may obsess over the wasted $300+ if they feel they bought a useless LSD and "stupid" 3.73's.

For what its worth, I am with those that lean towards the LSD.

The LSD helps whenever there are slick times, rain, snow, ice, etc. It may wear out sooner than an open differential and require different gear oil. If you decide you want both later, I think (correct me if I am wrong) a LSD or lockers would be cheaper to add after the fact.

The 3.73 will help if you tow, if you get bigger tires, or just want slightly faster acceleration. It also will make your engine rev higher on the highway and "Could" affect gas mileage.

To me going a bit slower, or lower towing rating is not as big of a deal as sitting there spinning in 2wd when its nasty out.

So, just found one with the 3.73 but not LSD and everything else that I want at a great price. For those who know Jeeps better than me (which is probably most of you!), would you lose sleep over not having the LSD?

OK.

Someone define "mall crawler" because where I come from a mall crawler isn't a stocker used for going to the mall.

Rather it is a Jeep or other 4x4 with big ass tires, lights and a lift that never / rarely gets trail use but has the "look".

You know... 35 MTs on 20" rock stars with about 6 PIAAs on the front

Nothing wrong with it, but it ain't a term for a stocker right?

I'm using the term as a stocker for just driving around town, going to the mall, kid taxi, etc.

Very well said! Wiser words could not be made as they apply well to a lot of our Jeep threads.

Get the 3.73's. My jeep is a daily-driver as well, and even the new pentastar is really slow when moving this much weight. You'll want the 3.73 to get a little more pep in the acceleration. As for the LSD, remember the jeep already has what is referred to as a brake-loc differential anyways. It's a system where the jeep applies individual brakes during slippage. This is all you need for light trail/dirt roads on those rare occasions you leave the pavement.

I would go for the 3.73s..and add the LSD or locker later. You can pretty much count the Mopar LSD to be sub par so go aftermarket and do it right if it is that big of a deal. I do not have LSD in mine but I do have 3.73s..to me the 3.73 was more important so I could tow. I also live in Georgia so the once every three years that we actually get snow is not a big deal.

In your situation, which is the same as mine, I would have a strong preference for the LSD over the 3.73 gears. Here is the reason. If you have the stock 29 inch tires with the 3.21 you have essentially the same overall gear ratio as the 3.73 with the optional 32 inch tires. You did say you would not be putting larger tires on it so that is the KEY point. I test drove both a 3.21 and a 3.73 with the stock 29 inch tires. I felt the 3.73 was too much with the stock tires. The revs were too high, in high gear on the highway, for a daily drive to suit me. I do not have an LSD but really wish I did. The LSD is a nice addition for a daily drive in the snow. Especially for the price. If you ever feel like you would put larger tires on then go with the 3.73. Otherwise the 3.21 is just about perfect in my opinion. But don't take my word for it. Test drive both and see how you feel about the gears.

Get both. Keep looking, check carmax for a '12, or expand your search. Never know what you might mod later and will help resale.

Just my. 02.

Enjoy!

I live in Anchorage, this last winter we had snow on the roads from Halloween until mid May. Never felt a need for a LSD. And I'm running the stock Sahara tires.

I have the old 3.8 engine, so I can't really comment on the need for the 3.73 gears. I would recommend test driving a Jeep with the 3.23 and one with the 3.73 to see which one feels better for you.

Gotcha.

If personal opinion mattered, I'd tell you to get 3.73 and an LSD.

It's a Jeep. It's never going to get great MPG.

LSD is a functional addition for the daily on road use of a capable off-road vehicle.

3.73 gears will be a bonus if you ever need to pull a trailer, decide to step up to a larger tire, and may help a little with resale.

But yeah, if I lived and drove in a flat area with no snow/ice -- just running kids around and wanted a Jeep, I would probably overlook most all of that and save money to install TV screens in the back for the young'uns.

I would go with 3.73. It will make your daily driving much more enjoyable and for your purposes you'll never really need the LSD.

Two words- Resale value. You may not want to mod your Jeep but others will. And they will want the better acceleration of the 3.73. The LSD applies only to the rear wheels. For the slippery stuff the 4wd is the answer. If you can get everything you want with the 3.73 then go for it. The LSD should not be a deal breaker.

I had 3.21 gears with the larger 32" stock tires.

The only reason I did that was because I knew in the first year I was going to upgrade to 4.56 gears and lockers to go with 35" tires.

I hated the fact that 6th gear was only useful driving down hill with a tail wind.

I drove around a full snow filled winter with the factory tires and only needed 4WD when I deliberately got stuck in a snow pile. I never needed or cared about having limited slip. Not even once.

Get the 3.73 gears if you're not planning on modifying the Jeep.

Well, I took the plunge and went with the 3.73! Test drove both the 3.21 and 3.73. The difference was very noticeable when accelerating or going up a hill. I don't drive aggressively but if I got the 3.21, everytime I got behind the wheel I would've regretted it. Would have liked the LSD too but the everyday driving experience won out over possibly reducing slippage once in a while.

Thanks for all your input!

Lol you folks are so spoiled, "must be able to use 6th gear" .

I drove a 1980 FJ40 with 3.73 gears back in the 80's, talk about underpowered on the road , talk about a beast off road! What fun it was.

I'm loving my 3.21 Polar Edition, it's all about knowing how to drive it. I'm a road warrior these days, not the same yahoo in the FJ40 of the 1980's, but it'll see some light off road duty perhaps. Oh well... I have to actually shift into 5th sometimes! OMG!, but I'll take the gas mileage in 6th when cruising along thank you very much!

(Towing is not a priority for me)

Cheers,
