I'm in the same boat. I bought a Trailhawk last December. Didn't come with a tow package from the factory. Which I wanted but it was the only one I could find with color combo and certain options I wanted/needed. When you build and price it says it adds the auxiliary transmission oil cooler but doesn't the Trailhawk model already come with one? If I add one, can I tow up to 4600 lbs or am I still stuck with 2000 lb towing rating? How can I fix it? I'm really disappointed I couldt find the exact model I wanted but the only Trailhawk model I could find with a tow hitch had a bunch of more crap on it that bumped the price up another $2,500.

Not a lot of hills I'm in Florida. But I would like to tow a pop up camper or a boat in the near future. Both can get close to 2800 lbs. I have an 06 ram 1500 truck that can certainly tow but it has139000 miles on it now and I'm wanting to get rid of it. Too much gas. Plus it's only 2wd. Is the gearing in the axles? My buddy changed his gears out in his truck not that long ago. Couldn't be that hard.

From your build sheet what gears did it come with? I thought the Trailhawk had the lower gearing already?

Build sheet here in case you haven't seen the link https://jeep.custhelp.com/app/jeep/e...WGxOMmc2T2w%3D

Mine is the V6 with Tow pack and I have the 3.517 gears acordung to my build sheet.

And I cant see changing them as being easy, they are not standard diffs like a Wrangler.

Not sure what my build sheet is. I'll look at it later. Hard to believe that a little bit of gearing goes from 2000 lbs to 4600 lbs of towing. Are the gears in the axle or the tranny? I would think with my V6 I could get it up to at least 3000 lbs if the 4 cylinder that doesn't add gearing with a tow package can tow up to 2000 lbs. The extra cooling is already there in the Trailhawk model.

Not sure what you are trying to argue here. If you are looking at doing this stuff to a vehicle, and you do not know how to do it yourself, take it to the dealer. Open your check book and tell them what you want done. The other option is to buy a vehicle already built to do what you want. This last option is what myself and many others did.

We are not randomly making up the towing specs. These are what Jeep says applies to various situations. You can drag around a flat bed with a Bobcat on it for all we care. It is your conscience that has to rest easy.

Adding the Tow Package after purchase?

With 4 of the top gears all overdrive I would say it's okay to pull 4500# on relatively flat ground. The engine cooling capacity (trail hawk) is there so heat rejection shouldn't be an issue.

The real concern I have is at very low speeds like pulling a trailer/boat/camper around where the torque converter is in stall at lot. The trans oil will get hot faster with the taller gearing. To get around this just use 4lo whenever maneuvering a heavy load at really low speed for more then a few minutes.

Also keep,the frontal area of your trailer at or below what is specified in the owners manual.

Watch your trans oil temp and you will be fine (under 230 deg f). The trailer towing capacity is specified at very high ambient temperatures (110deg F) usually so if it hot outside back off on towing loads.

Most people on this forums have no engineering background to support there opinions.

The question is what can I tow with no factory installed parts. The parts to include wiring harness to plug into (no effect on tow rating), 2" receiver same with 2,000 lbs and 4,500 (same) if using a class 3 add on still good for all ratings. Engine 2.4 limited to 2,000 lbs in all situations. 3.2 is needed for it to pull 4,500 but with limitations. Aux cooler part of the factory tow package, this is need to handle the extra heat. Now is where factory or dealer comes into an issue with out the cooler you could still pull the 4,500 lbs but you would be responsible for the transmission temps and would possible to void the warranty as your vehicle was not rated for that load. Same is true for the gearing a lower gearing is to take some strain off the transmission so it you pull and break it could void the warranty. So would a Dealer installed tow package work yes, would it be covered by warranty? probably not. Get it in writing from the dealer that they would cover anything the manufacturer would not (bet they won't) the difference is what the manufacturer will cover not what the vehicle can do. The old rule is your max tow is the rating of the weakest part. On a v6 trailhawk with the tow package it is the max vehicle weight 4,500 lbs if you go down in hitch or even the ball then it would be whatever the weakest part is. I hope this breaks it down to the basics.

Thanks. This has been a help. I'll check it out with maybe getting a hitch on. I wasn't looking to tow any more than 3000 lbs. just didn't want to be limited to 2000lbs like a 4 cylinder.

I wouldn't worry about it. Just watch the gauges and don't enter any tractor pull contests!
