Question 2012 sahara with 3.21 gear ratio towing capacity ?

Purchased a 2012 sahara new from dealership. I was under the impression I had a 2000 lb tow capacity. After purchase, and a long drive to pick up new teardrop (1300 lbs), the trailer place brought it to my attention that I only have a 1000 lb tow capacity with a 3.21 gear axle ratio. So.... now after a lot of research (and a whole bunch of misleading advertising by Jeep and Chrysler)... I am wondering if anybody can help with re-gearing info, or how EXACTLY do the tow capacity charts work out. As far as I understand so far, to be able to tow 2000 lbs with a 2dr jeep wrangler sahara, I need a ratio axle of 3.73 (at least) and the 'Tow Group'. I also don't understand how Jeep can advertise the 2000 lb tow capacity and EVERY 2 dr jeep I can find in inventory at dealerships say that in the advertising , but all the window stickers say they have a 3.21 gear ratio. Can anybody help explain how it works, and if it's possible to modify the jeep to be able to actually tow 2000 lbs.

Gotta read the fine print...

There's a little asterisk (there's always one of those damn things)..."When properly equipped. See dealer for details."

Here's a good thread with the info you're looking for
2012 JK tow ratings with the 3.6L

OK. So if I am stuck with 1000 lbs, is there any way to modify or upgrade or change anything to get up to 2000 lbs ? I still can't imagine how all these dealerships are STILL saying they have a 2000 lb capacity, and yet right on the window stickers they all say 3.21 (of course they leave out the rest of the info, and the average idiot consumer like me doesn't have any idea what the axle ratio is supposed to be). Very misleading, on the website too. So what do I do at this point? Sell it and get a new one built at the factory Correctly ? or just live and learn ? What is 're gearing' and what exactly do they do to the vehicle to change the tow capacity, or is it not worth it in the end anyway ? I'm trying to travel with my new Jeep and a 1300 lb tiny teardrop trailer. Thanks so much for your input.

It is my understanding that there were some misprinted manuals but 2012 and newer can pull 2000 lb no matter the gearing. The jku with 3.21 can tow 2000 while the 3.73 and 4.10 can pull 3500. Someone chime in if I am incorrect

you will be fine

I had towed a Silver Shadow 5x10 tear drop with a 2013 (2) DR with a 3.21.

I sold that camper and have a 13 ft Scamp. I towed that from Wisconsin..to Utah..through Durango/Ouray with no problems at all.

You may want a transmission cooler. I think 2012 they were an option. All 2013-2014 have them standard.

JK with 3.21 is rated at 2000lbs, prior 2012 it's rated at 1000lbs from what I understand. Bring your manual to the rental shop and show them. JK with 3.73 or 4.10 is still rated at 2000lbs.

JKU with 3.73 or 4.10 is rated at 3500lbs.

All that's required for 2000lb towing is the Trailer Tow Group = Trailer Tow with 4-Pin Connector Wiring.

CDBillet13, if that's true I'm very happy. The mechanic at the dealership that installed my tow hitch receiver and electric looked it up and told me I'm stuck with 1000. However, nobody seems to be very confident when I ask them, and they all pull up the same spec sheet from Jeep/Chrysler. Just for the record I purchased a 2012 Sahara 2dr, 3.21 ratio, 6 speed manual tranny v6 brand new left over on the lot in the beginning of 2013. No cooler, no sway control, no extras, other than interior options and fluff. AND ..... to bcsnave .... I've been looking at Little guy, Signatour, and Trekker tow behinds and they are all under 1000 lbs, but really what I was planning on was a T@B and it comes in around 1500 lbs. Now I'm just afraid to do anything, and I already drove up and down the East Coast looking at teardrops and had a plan that I think is shot to PooPoo. So now, the Jeep isn't even a year old, I put about 30000 miles on her (and I'm already in love) installed a sick Garvin Safari rack, and got her all ready for a big cross country road trip. I know the 2dr jeep prob. wasn't the best choice for coupling with a trailer, but the tent thing is getting OLD, lol... and so am I.

undermoose ... you mean bring the Jeep to the Dealer's Shop? or the Manual ? The manual still says 1000 lbs. for 2012 sahara 2dr with 3.21 axle on the tow chart in the user guide.

I think

if the dealership "installed" the tow hitch, then it didn't "come with" the tow package.

not sure

Lightbulb My 2014 Manual clearly states 2000lb towing.

I'm positive 2000lb towing is clearly listed and only the trailer tow group is needed which is the tow and the wiring. Pretty sure you can have the trailer tow package added, not the max tow because it involves re-gearing which most dealers won't touch in my area. I don't think there is a "max tow" package for a JK, just the JKU, and it's for 3500lb tow package.

Trailer tow group, build a Wrangler and click the "I" on the Trailer Tow Group option. It's just the tow and the wiring, all the stability goodies are built into even the base Wrangler.

Change to 2013 Model Year after clicking this link, then Wrangler, for towing details. 2012 says the same thing. Write a letter to Chrysler and get a formal response, then pack it away with your 2012 manual as proof.

Explore Jeep Capabilities | Towing Reference Guide | Jeep*

From what I've read, prior 2012 the 3.21 is 1000lbs. Add 40% more HP and 3.21 pulls fine, if you're towing daily then get the lower gearing, but if you got the lifetime warranty WHO CARES LOL (except a break down would really suck).

I did some poking around myself and found that it did change to 2,000 lbs. across to board as the standard max weight for all JK's.

However, there are no printed Owners Manuals that I can find for the 2012 year that actually say this. The 2013 Owners Manual however was changed. You can check here: Jeep Owners | Download an Owners Manual 2004 - 2011 | Jeep

My 2012 manual shows 1,000 lbs for the 3.21 as well.

The only document that I found (from another thread on this board: 2012 towing capacity?) that actually specifies 2,000 lbs for 3.21 on a 2012 JK is actually not posted on what seems to be a US site, but seems to be legit: http://www.jeeppr.com/jeep/pdf/2012_...gler_Specs.pdf

Check my link above. It's very clear, and yes 2000lbs no matter what gearing for the JK. JKU with Max Tow package goes to 3500lbs.

Select 2012 or 2013 model year Wrangler once you click it. Here again: Explore Jeep Capabilities | Towing Reference Guide | Jeep*

you guys rock ! Thanks for the input. I'm going to email Chrysler and send them my VIN and ask them point blank what the hell my tow capacity is and what do I need to 'up it'. I was led to believe (at the point of sale) I was 'properly equipped', but the 'tow package' (tow hitch, and electric plug) isn't a TRUE tow group, and it was added by the dealership shop as a 'we owe' after I signed the papers. So I think basically .... I am NOT 'properly equipped' after all, and still only have a 1,000. tow capacity. AND .... prior to THIS experience with the 2012 Sahara and (having owned a 2008 Jeep Sport X previously) I never knew anything about Gear ratios and axles and blah blah blah.... I just figured if the spec sheet and the dealer and the big fancy flyers said 2000 lb tow capacity, I didn't need to actually become a mechanic to calculate my REAL tow rating. My mistake I'm sure. But pretty crappy on the part of the dealership if this is the case when all is said and done.

You are equipped, read my posts above again, the Trailer Tow group is just the tow and the wiring, and dealers can add it.

2012 and up JK can all tow 2000lbs legally. Check the link I listed.

Write Chrysler, get the proper person to write to from customer service because the first ranks of customer service will never document anything for you.

Good luck!

Undermoose,.. I downloaded and looked at the manual you linked for me. I put in 2012, Wrangler, Owners Manual then it gave me the download and On page 473 in line 4 where it says 3.6L Manual - 3.21 - 2dr Sahara - 1,000. lbs ..... am I not reading right ? Sorry I'm so needy, I am getting confused.

The link I posted is towing capacities, nothing to download. To the right of the chart is the model year selection, then select Wrangler on the tabs.

Undermoose .... sorry I referenced the owner's manual. On the website for jeep, on the link YOU sent me (got it screwed up a little) .... It says 'when properly equipped' 'see dealer for details' .... then when I look in the owners manual the DEALER provided, it says 1,000. lbs. That's where I'm getting confused. It seems to me, the advertisement of the vehicles capabilities are misleading, and then when you get to the nuts and bolts of the thing, the User Guide and Actual Vehicle Owner's Manual says otherwise.

Properly equipped on a 2012+ JK for 2000lb towing is the optional tow package which, again, is just the Tow and the Wiring. You can't get max tow on a JK, gears don't affect the rating.

Dealers can install the Tow and the Wiring harness.

Done.

Now if you want to pull more than 2000lbs on a 2012+ JK (any trim level, and it'll be illegal n public roads in the USA) you need the lower gears, but maybe you're towing on private property, not sure if that's illegal...

Undermoose, You ROCK. Thanks so much for your time, sorry I'm a pain. I wouldn't try to go over 2000 anyway. I was looking in the 1100 - 1400 range and it's only me and gear inside the jeep so I'm ok to go cross country. If it was only 1,000. it would be out of the question. I just want to be out of the rain and camping in a little itty bitty teardrop trailer with my Jeep, and all this was brought to my attention by the trailer guy who was afraid to let me buy the thing without making sure, because he couldn't figure out the Owner's manual specs either. LOL. Thanks again !

This is the best thing you could do at this point for piece of mind.

As I said before, actual documentation for the 2012 is limited with the changes (if you can find them)...2013 and later documentation was fixed.

I'd still get the contact to write from Jeep customer service and get them to confirm it. Having something in writing if you run into an issue would potentially save you much grief. For my part, my manual is my proof. Maybe Chrysler has an updated owners manual in print for 2012, and you might be entitled to it free? (maybe!).

Thanks sduphily, I wrote them a letter, and hopefully I can pin somebody down to a formal response, and you bet I'm gonna keep it right in my folder ! Thanks again you guys, for the help. Very cool to be able to get input from out there in the world when I don't know what I'm doing. Happy Jeeping ! Wish me Luck !

Let's be clear.

A letter, not an email, will get you a letter in response from Chrysler, or an initial phone call from them with follow-up "in writing". That piece of paper on Chrysler (FIAT) letterhead is what you want.

The important thing to save yourself some red tape is to get the correct correspondence address from Jeep customer service department. Also attaching the case number they provide you to your letter in reference can help.

Good luck!

Yup, the 2012 owners manual for all messed up. Even the early 2013 manual for messed up. There were at least 6 editions of the 2012 owners manuals, and they still didn't get it right.

I have a 1000lbs Livin Lite tent trailer I pull with my 2dr sport 3.73 geared without a single issue, I mean I almost do not feel it back there. I had a tundra I was pulling a 30ft trailer with and you felt that like a mofo, but the 1k lbs tent trailer is nothing.

Jeep Jk tow capacity

If you look online at the 2013 JK Manual you will see that all JKs with the 3.21 axel ratio were updated to a 2000 lb capacity. The 2012 and 2013 are really the same so this should be an update. I intend on occasion to tow a travel trailer with electric brakes that is less than 2000 lbs. and also using a brake controller for added safety. Using a travel trailer that doesn't exceed 2000 lbs and a tongue weight under 200 lbs, and with an electric brake controller and considering the trailer is half the weight of the 2 door 2012 or later model should be a very safe operation.

I just spoke with Jeep customer service today who opened a case number with me to clarify the tow capacity of the 2012 Jeep Wrangler Sport with 3.21. As people pointed out here on this site some Official Jeep publications show a 1000 lb capacity and some show 2000 lbs for same axel ratio. So the rep is going to go back to the factory engineers and point out the discrepancies in the published materials and come back to me with an answer within the next week, when I get the answer via email, I will try to put the response back up on this site.

We appreciate the effort, but keep in mind that this has been hashed out.

However, it sounds like you had better look with a service rep than I did when I tried to point out the discrepency to Jeep nearly 2 and a 1/2 years ago when the 3.6 firs hit them market. The service rep simply told me that 3.21's with automatics were not available in North America.

Now that every poster here has hashed and hashed what is or isn't in the owner's manual, how about I weight in about the real world, as someone who has towed with a 2dr Sahara with 3.21's and a DEALER installed hitch and wiring. Granted my jeep is a 2011 with the 3.8 and 6 speed. The 3.6 in the 2012 developes another 25 hp, granted it's at the upper rpm level. I towed an open trailer (aprox 400lbs) with an 800lb Harley decker, kayak and assorted totes loaded on, so lets weigh in at 1400 lbs, what jessiesjeep figures he's aiming to tow.
In the flat lands - no problem, up state New Hampshire/Vermont in the White/Green mountains - workable, as in your gonna be working that 6 speed.
The ability to choose your gear and keep the (for the 3.8) rpms in the 3,000+ range will get you over anything you think you can tow a trailer over. We drove on average 8 hours each day (going from southwestern Ontario (Canada) to coastal Maine) and other than it being a pig on gas, I experienced no overheating problems, brake fade or "wobbbles" from the trailer, that were not directly related to the fact the road was sloped downward at 45 degrees on both sides of the center line. They have got some god awful roads in those states! I will freely admit 3.75 gears would have made towing a lot easier but the lack of them only meant more shifting to stay in the power band.
So jessiesjeep, I suggest you chuck that manual back in the glovebox, hook up the trailer and take it for an hour drive over everything you think your gonna encounter and then decide if your jeep is rated for 1000lbs or 2000lbs.
Just my opinion.

The 3.21 has a 2000 pound tow capacity. The 2012 owners manual is wrong. Jeep customer care looked into it for me and contacted me today confirming the 2000 pound tow capacity.
