JK Towing experiences
 
I have a 2008 (my first) with a 3:21 rear end. I want to tow a popup. Everything I've read so far tells me that the towing capacity is 2000 lbs. Looking for any experiences anyones had towing a popup with a JK?

Thanks

I thought towing was 3500 lbs?

Dewayne 05-04-2009 04:07 PM

From what I 've found the 2 dr is @ 2000lb towing the 4 dr is 3500 lb .The 3.21's seem to get the trans hot . Changed my gears to 4.88's to pull boat and pop-up. By the way mine is the 4dr. Before mine was 3.07's and it HATED pulling my boat (17' Alweld with 45 hp Jet) .

Welcome to the forum.:wavey: I've towed with the Sahara unlimited and the Rubicon unlimited at near capacity (3K of the 3.5K) and didn't notice too much difference. Both were standards. The Rubi seems to have a bit better torque up hills. Transmission heating is not a problem on the standard and that is one of the reasons I highly recommend it. I chose the unlimited over the 2 door mainly because of the towing capacity. Hope this helped. Give us more info if you are looking for something different.

Badfish 05-04-2009 04:35 PM

the rubi should feel like it has more torque because of the lower gearing 4.10 vs 3.73

jk'n 05-04-2009 04:55 PM

^ Hi Badfish,

Yah, I knew that. The difference on the standard between the two gear ratios was hardly noticeable. With 6 gears it makes it even less noteworthy because if it bogs down, power is usually one gear down away. :)

hig4s 05-05-2009 09:40 PM

All 2 doors are limited to 2000lbs because of the lack of stability of the short wheelbase. 4 doors are 2000lbs with the 3:21 gears, 3500lbs with 3:73 or higher.

AndyLA 05-05-2009 10:07 PM

^ Not as much to do with wheelbase as much as vehicle weight, suspension, and cooling capacity within the drive system. The 3.21 is major limitation. However, I would rate the safety factor at 75% if not at least 100%, so for short distances you could exceed, but the overloading will become apparent quickly. Jeep (JK) is not a great heavy-duty towing vehicle.

BeerMonkeY 05-05-2009 10:48 PM

i towed a pop up with my 2 door rubi on 35's with no problem, i have no idea what it weighed as it was really old, i also towed our small travel trailer thats weighs 2600ish and it towed fine, if you are towing something with brakes make sure you get a good brake controller

AndyLA 05-06-2009 07:53 AM

One could tow just about anything with anything, it doesn't make it safe.
It is about the safety load factors that affect stability, braking, sway & powerplant cooling.
With the heightened 35"s, you are offsetting your inherently poor CG and increasing the
likelihood of lateral force imbalance. Along with the shorter wheelbase, it is just not a great solution. However, if the distance is short and the speed under control, there is nothing glaringly wrong about towing something over your recommended load rating.

BeerMonkeY 05-06-2009 08:17 AM

i didnt tow the larger camper with the 35's, still had the stockers when i towed it. id say hes safe with a pop-up camper even if its right at 2k, the nice thing about the pop up is the roof line is below the jeep. when i tow out pontoon boat to the lake (about a mile away) i cnt go over 40ish just becasue of the wind resistance of the boat ( i have a bunk style trailer so the boat sits pretty high) id bet my old pop-up wieghd as much as my pontoon boat

highcard77 05-06-2009 10:24 AM

Sway control new for '09
 
check it out...if you have a '08 2-door with 3.73, you can tow 2000lbs. If you have a '09 2-dr with 3.73 you can tow 1000 lbs unless you have the tow package, which includes the new Sway control programming (adjust braking when sway is sensed) then you can tow 2000 lbs. What the Hell !!

thaduke2003 05-06-2009 10:57 AM

^ He meant 1000 if you have 3.21's :)
And the short answer to the original post is I sure as hell wouldn't reccommend or try it, unless it's an old mini-truck. Not a big fan of towing something bigger than my tow rig unless I'm in a real truck (preferably diesel :))- Mark W.

Towing a boat on a trailer with the unlimited 2WD 3.21
 
Have plans to tow a 2900lb boat with my 2008 wrangler unlimited, from Minnesota to Miami. My jeep has manual shift, 2WD and 3.21 rear axel. The Jeep dealer told me, after checking with the mechanincs, that I will be fine, little slow at the start but fine. Only thing they said is to service the transmission before I go. What do you think? I want to be safe and not worry every minute of this long ride..

jk'n 04-06-2010 04:14 PM

@jetblue

First, welcome to WF. :wavey:

I went to look to see if I could determine if you have a 2 door or 4 door model because 2900 will exceed the towing capacity of the 2 door by 900 lbs. If it is the 4 door then 3500 is the limit and 2900 is well within it. That having been said, my experience towing in the vicinity of 3000 for many miles between MA and Maine is that care must be exercised while doing it. Jerking the steering wheel will produce oscillation if you do get into an ocillation situation don't try and compensate just hold the wheel steady straight ahead and the trailer will settle down. At that weight, care must be exercised in keeping good distance between you and the car in front, you will never know when a sudden stop will occur in heavy traffic. Things can get out of control pretty quick in that situation. I see cars and trucks towing traveling well beyond the speed limit. I would recommend keeping it within the speed limit and relax. My tendency while I am towing a heavy load such as my utility trailer is to tense up on the steering wheel. The faster I go the more I tense (to a degree). I try and remember to relax when I get into that feeling. Turning in sharp turns should be done slow enough to keep things under control and sometimes you forget that the trailer is back there so be aware in cornering that if going too fast and especially if there is sand, trailers can slide sideways. That will end badly if it gets out of control around a corner. So, when off the interstate this will be a concern and it requires constant awareness of the forces caused by that much weight behind the jeep. When I first started out with my new trailer, I was pretty nervous. I didn't know how it would stop in a hard braking situation and I knew I had to get from point a to point b. As you begin to feel how it handles, you will get used to what it can do. I drive with a lot more confidence now than when my rig was new. Not cocky, just confident. Best of luck on the trip and safe driving. Hope this has helped.

jetblue 04-06-2010 05:05 PM

Thank you JK, your suggestions about the driving make perfect sense. Just to re-confirm, I have a 2008 wrangler 4 doors, 2WD and 3.21 rear axel. Like many other guys here, I have had confusing information about the towing capacity of my jeep. It is still not clear to me if the 2WD, 3.21 axel garantees 3500lb of towing. I'm worry that only the 4WD and 3.74 axel will do that. I would really appreciate if you or others can clarify this point. Jet

I put the two entries in red that should pertain to your jeep. I think that the second red entry is mislabelled as standard but should be automatic. Regardless of how it is labeled, the weight limits for the trailer is 1000 lbs gross trailer weight and 100 lbs tongue weight. Most insurance will only cover up to the weight limit that the manufacturer specifies.

Towing
 
Thanks JP, but don't you find strange that huge difference between 3.21 and 3.73 axels? From 3500lb down to 1000lb? I know that the lower axel has less traction, but it is the same car... and what can you tow at 1000lb? almost nothing..

JIMBOX 04-07-2010 11:16 AM

:D It's not traction, it's engine/xmission load and its not a car

The higher diff. gears put TO MUCH load on the low torque engine and gear hunting xmission

You can easily tow this one at 900 lbs

Course I don't have 3:21 gears

We tow a Coleman Sequoia popup with our 2010 Unlimited 6 speed. It has the 3.73 which came with the tow package. This includes the anti sway feature. The vehicle is bone stock at the moment.

We have had no trouble towing up to about 3 hours at a time. I take it easy and keep the speeds down when maneuvering, but on the freeway it is fine. Haven't been up and down any real hills in it yet so can't say how that goes.

I think my manual says our popup has a GVWR of 1995 pounds dry. I'd guess it is less than 2,500 pounds total loaded at most. That's about 1,000 pounds under the 3500 pound towing limit for our Unlimited. Seems to work great so far.

Boosta 08-22-2010 06:37 PM

I know this thread is old but how do I detemine which Jeep gearing I have? I am trying to detemine my tongue weight. TIA

jk'n 08-22-2010 09:42 PM

Tongue weight? Look in your manual for the maximum and figure 10 % of your load should be on the tongue. If loading a utility trailer try and keep most of the weight over the axle as putting too much weight in front will cause more than 10% of the weight to be on the tongue. On a four door the tow max should be 3500 and max tongue weight should be 350 lbs.

JK Brake Controller
 
I got a new popup and it is right at the limit for my 08 JKU so I would like to take advantage of the trailer brakes. I would like to know if I need to install a brake controller along with the 7 pin harness or if the controller is built into these vehicles? I have already wired my own adapter to mate the OEM 4 pin plug to a 7 pin. I didn't know if I could just run the extra couple of wires myself and maybe a controller or if I needed to start completely over with the Mopar 7 pin harness and maybe a controller with that too. I am really new to this so any advice would be greatly appreciated.:)

thaduke2003 09-05-2010 04:48 PM

Ok- instead of adding onto an old, semi-related thread, try starting a new one. You'll get better results that way. Also, this is called "thread jacking," and considered rude.

That said, the only vehicles that come with integrated brake controllers are vehicles MADE for towing, e.g. trucks. You'll need to add your own brake controller aftermarket- Mark W.

chcooper2002 09-05-2010 09:04 PM

Ok duke, thanks. I'm still learning here. I will try to avoid "thread jacking" from now on.

DavidGoodman 07-09-2012 04:36 PM

Dewayne,

I'm about to travel the same path. I'm looking at a 20' Boulton to pull behind my JK 4dr. Unlimited.

How much did it cost to have the gears changed?

flat tow steering issues
 
I Have a 2008 Wrangler X w/ 3.73 gears that I have driven 48,000 miles & flat towed another 40,000 miles. It has a steering lock & is an automatic. Its been a good unit w/ a few issues that Chrysler's warranty has taken good care of.
I have read everything posted about flat towing Jeeps because on 4 occasions the steering has locked in the middle of the day, generally one or two clicks from straight ahead. My tow unit has a rear camera & a microphone so I have caught it quickly. Each time the key seemed to be less than one click away from off. 1st time I thought it was me, 2nd time started to suspect me/or the ignition lock, 3rd time I began to suspect vandalism, the last time I started searching for others w/ similar issues.
I have jacked up the front of the vehicle until the front tires were barely touching & cranked the steering full left and full right a couple of times. The column did not lock & the key stayed @ the 1st click.
Each time the vehicle doors were unlocked, it was a mid day fuel stop involving some sharp turning & maybe a significant bump or two. My next step is an unencrypted key in the ignition and locked doors. Disabling the lock is tempting also. Didn't realize that later models don't even have the local.
Anyone else have a similar experience?

Don't worry, be happy.

Jayco Sport 8, unloaded weight 1,200 lbs, max weight 1,995 lbs. I have one and love it. You are good to go.
