Towing Capacity

I have a 2012 JKU sport with 3.21 gears, automatic transmission and have read that the towing capacity is 2,000 lbs. Assuming this is accurate, does the fact that I have a 2.5" lift make a difference in capacity?

I haven't seen anything official, but I would think a lift will lower the tow capacity because of the higher center of gravity.

not an expert, but if you used a drop hitch, i think you would fine.

Thanks for the quick response! Do you guys think I could tow a little more and be fine? I realize the insurance ramifications if I get into an accident...

By JKU you mean the unlimited (4 door) correct? All unlimiteds have a towing capacity of 3500. If you lift and put on larger tires you may need to re-gear especially in a towing situation with 3.21s. Lifting does cause some instability but some type of sway control will really help. Also when towing, if electric brakes are on the trailer, a brake control sure is helpful.

3.21 gears limits the tow capacity on the 4dr.

In the 2012 owner's manual, it says 1,000 lbs.
In the 2013 owner's manual, it says 2,000 lbs.

I suspect the 2012 owner's manual was a leftover spec from 2011, as the 2013 used to say the same, but has been updated to the 2,000 lb. figure.

Right you are, so with a re-gear and a hitch on a 4-door should be able to increase max tow capacity to 3500 lbs.

Properly equipped means weight distribution hitch and trailer brakes also. 350 lbs max tongue weight.

I am not sure about the state you live in, but you can not tow more than the factory specs no matter what you do to it. Unless your state offers some sort of re-certification.

You are partially correct. Nothing can be done to increase the max tow capacity.

However....

Going from 3.21 to 3.73 or 4.10 gears does increase the tow capacity of the 4dr from 2,000 lbs. to the max tow capacity of 3,500 lbs., because that's all it takes, according to the owner's manual.

I agree with what you are saying except that does not change the tag on the Jeep which states what your towing capacity is. If the tag states 2000lbs then that is all you can tow no matter what you do to your vehicle.

What tag are you referring to?
Registration? There is no reference to tow capacity on my JK's registration. (Maybe some states have that?)
Stickers on the B pillar? No reference to tow capacity there.

I will admit that I have not looked at my JK specifically but every truck I have ever own and trailed with has a tag in on the inside door pillar which states GVWR which is the weight of the vehicle plus payload and GCWR which is the combined weight of the vehicle plus trailer. Subtract these amounts and you will find your tow capacity. If you get pulled over by a cop towing what appears to be too much weight this is the tag he/she will check to find out what the OEM rated the vehicle at when it left the factory, ie 2000lbs or 3500lbs. Even if you regear, upgrade shocks, or upgrade springs your GCWR will not change. Again I will check the JK when I leave work this morning, but I am sure it has the tag. I know people who have de-rated their trucks in PA because they can charge you additional fees for registration and Turnpike fees depending your weight class. If I am wrong about the JK, then I have learned something new.

No reference to GCWR on the stickers on my JK's B pillar.

Maybe there is on the later JKs?

I've never seen GCWR on any sticker. Only in the manual. It doesn't mean some dont have it but I have never seen it.
