Increasing Tow Capacity of 2 door JL

Purchased a 2018 JL 2 door. Told it had 3500 lb tow capacity. Only 2000. Have been to some shops and they said that I can replace the Class II hitch with a class III and I would be good for 3500. They also recommended air bags on rear springs. Want to tow a Casita, 2480 dry. Have the factory tow pkg. on the jeep already. Still feel hesitant. Need some thoughts on whether this is a good idea or not. Thanks in advance. Anyone else tow with a 2 door?

Stretch the wheelbase about 36"...

The short wheelbase is the problem. Not a good idea.

You cant change the tow rating after the fact. Your particular vehicle has been registered at #2000 and no matter what parts you add or change you cannot legally increase the rating the vehicle was assigned.
Generally max tow is the same Class II hitch but they also have different gearing.

Make sure to keep those shops in mind for where Not to go when/if you need any work done.

That said... I would always have a class 3 receiver just because the stability it affords when using a hitch hauler, bike rack etc.

What’s the difference between the class II and Class III hitch on the JL?
The factory Max Tow hitch is only a Class II 2” receiver.

As long as the receiver is 2" it's good. I mentioned "receiver" class lll receivers are 2". Class ll are 1.25".
The 2" gives you more stability.

Doesn't change the towing capacity but makes for a better receiver.

There apparently has been some discussion about this. The factory hitch is listed as only a Class II even though it has a Class III 2” receiver.

Yeah one of those topics ... But for your benefit it's good with the 2" receiver. I hate 1.25" trying to carry anything twists and turns. Useless.

What trim level & axle ratio do you have?

I have a 2 door JL Rubicon at 4.10 ratio. It’s suppose to tow 3,500 pounds.

You can upgrade your hitch all you want. It won't change what the Jeep is.

Well the 2 door JL is only rated at 2000 lbs with a 200 lbs tongue weight, should of bought a 2016-2018 JK 2 door. From a legal stand point there is nothing you can do to change this except potential submit it for testing against SAE J-Spec 2807. Of course that will probably cost a few thousand dollars.

But even with a 4 door I am not sure I would consider a Casita trailer. Casita's require a very heavy tongue weight, 365 lbs for the 2480 dry weight trailer. Wet you are probably looking at close to 500 lbs. With that kinda of tongue weight there is not a hitch available for any Wrangler that will handle it. Better of with a Gladiator for this job.

I had a JK 2 door sport and as an experiment I towed our 17" casita to a campground that was only 20 miles away. After that trip, I never did it again. The jeep did fine, but if I would have had to taken any emergency stops or maneuvers, it would have gotten ugly FAST. I even temporarily installed a trailer brake controller, but the problem was with the short wheelbase. Sorry to bring you the bad news. My avise would be to plan to tow with something else. BTW the Casita trailers are pretty cool. I dont have mine anymore because my family outgrew it. Good luck and happy camping!

I towed a Pop-up with my two door with a round trip from Denver to Yellowstone. I avoided the interstates when I could and did a comfortable 60mph. 4.10 gears, 35" tires, Manual Transmission, 3.8 motor. It was a lot of work, but still pretty fun.

Now I am pushing it with the current setup. 19FT Starcraft, 35" tires, 17 JKU, 5.13 gears, Automatic transmission, etc.

Should you choose to push your setup beyond what the specs are consider the following:
- A decent bumper that has an integrated Class III Hitch. Only a few companies make them. They have a few extra attachment points over the factory hitch. (At least on the JK)
- Look at the Redarc brake controller. Clean neat package.
- A weight distribution hitch with integrated sway control. Air bags will not dampen any of that sway or balance the weight.
- Gears as mentioned above will make your mountain passes not so horrible.

As has been stated before you can't change what the vehicle was rated from the manufacture. So if you pull over weight just be aware that it could lead to a lawsuit if involved in an accident.

But I regularly pull over 2000 lbs with my JK 2 door and my trailer does not have brakes nor do I use a weight distribution hitch or sway control device. I have had to make emergency stops and maneuvers and was surprised in how well it handled it.

But my Jeep is not stock and to add to what @Shadowmaker said I would also upgrade the brakes. I don't know about the JL but the JK's brakes stock are barely adequate so when going to larger tires or pulling a trailer that is a must upgrade in my book.

The other thing to he touched on is to slow down. Trailer sway is a phenomenon of tongue weight and speed. I tend to run my tongue weight as light as possible, normally between 5-10%. But I never exceed 60 mph. If going faster you need at least 10%. Wind can also cause it so again slow down or pull off the road in windy conditions. Also slow down when approaching semi's coming in the other direction on a 2 lane road.

There are many things to learn when towing and the closer you get to the max the more important they become. I am still learning after 40+ years of doing it.
