I want to know what do you think about towing a fold-down camping trailer of 900 kg with a 2drs jk 3.21 and 35inch tires manual tran.

 

I wouldn't do this on a downhill. when my unlimited was stock i towed a 2 place snowmobile trailer on the highway and never left 4th gear. i think it wold be very hard on her, do you at least have a flashpaq or another programmer?

 

No programmer just the AEV procal.
What kind of programmer would do the best job for what I want ?

 

A - the trailer empty is already above your 2000lb tow rating (2dr)
B - 3.21 gears and big tires

Might be possible, but just borderline. You'll never know until you try. Have you already got access to the trailer to try it out?

 

With 3.21 gears, the 2dr JK is rated at 1000 lbs tow capacity. The 35" tires reduce it further.

 

The manual helps a tiny bit, but I wouldn't do it.

My 4 door with the 3.21/6 speeed and 265/75/16's is able to tug my popup for short trips without issue as long as I forget 6th gear completely.

My popup is a little lighter (830kg). 35" tires, heavier camper and a shorter wheel base? Lot's of luck.

I plan to re-gear to 4.10 as soon as I am able to find a place to do it within driving distance. Most of the time, my Tahoe serves to pull the popup and the Jk follows.
