Towing capacity of ProRock 60s
The debate of HP rear axle and towing....
I have the ProRock60 front and rear with 5.38 gears and will be putting in a 5.7 hemi next summer. i want to be able to haul a pop-up camper, or a trailor with ATVs/UTVs on it (5-6K lbs)...
I would have thought that 1 ton axles, and 300+hp would pull this easily but some na-sayers are telling me that a HP rear axle is running on the coast side of the gears and that it would not be smart to haul anything with that axle...
Anyone have any ideas, thoughts, or answers???
I have sent an email to Dynatrac, and i know they have an account on here so hopefully they will chime in.

The towing capacity for european JK models is much higher than US models--something like 3500 kg instead of 3500 lbs for a 4 door.
I recall reading somewhere that it had to do with tranny cooling, and possibly braking.
If you really want to increase the towing capacity of your JK, you would run rear leaf springs instead of coils--4wds has a setup like this. With the right cooling and braking, your capacity would probably be as high as a 1/2 ton truck with the stock JK engine, and even more with a Hemi.
If you add a tranny cooler and rear airbags (the kind that fit inside your coils), you could likely tow much more than the stated stock JK capacity--with trailer brakes. However, your lack of insurance coverage and potential liability would be the things you should be concerned about.
The towing capacity of a V6 Liberty is something like 5k lbs. For the V6 Grand Cherokee, it might me more. (You could find the info on jeep.com.)
I really wouldn't worry too much about it other than the liability.

Air bags won't send any weight to the front axle or to the trailer axle.
