Agree, they don't provide much info about the payload package. Also, the payload package requires the max tow option, so some of the things they mention as a HPP feature are in effect due to the max tow options. Both options claim to upgrade the transmission cooler for example, but it's not like you get a second one or a double upgrade - (you just pay for it twice). Add that you can't find these easily to see the difference for yourself and it creates a mystery.

As for tow rating, I suspect we have the same hitch - rated for 1200 lbs tounge weight. The practical difference is the ability to use the full hitch rating and still have payload left for a cab full of people and a box full of stuff.

 

I was wondering this exact thing, but for the 2.7 eco. The payioad package for the 2.7 eco includes a 9.75/3.73 axle, but you can also order a 3.73 axle alone as an option. Does anyone know of this is the same 9.75 case as in the 2.7 payload package or are they using the smaller case.

THanks

 

I cant look up the costs at the moment as they are no longer on the build an price but when you get the max tow option on its own, it cost one price but when you combine it with the HDPP it drops down in price to compensate for the double up of items.

 

I've seen what you're talking about, and figured I'd have that pointed out to me when I put in the snide comment about paying for it twice. Reason I chose to order the HPP was mostly the frame upgrade, and I think that is where most of the extra cost goes. The fact that it needs a frame upgrade to get the ratings is something I used as a clue that attempts to upgrade with aftermarket changes was likely to leave me short in critical ways. I do suspect the axle and cooling system on the HPP is the same as the ones with just the max tow option. Which in some ways is a good thing because our trucks are too rare and finding the right parts 10 years from now would be a nightmare if it was a unique HPP part. The frame and springs are clearly the most unique parts, and I'm not worried about them. As you saw, I'm not impressed with our cooling upgrade, but I'm not upset about it - that's just the only aspect where I was hoping for more. But there's only so much space under the hood and I'm confident they've managed the margins of what's needed. Worst case is maybe someday if I decide to take 12000 lbs up the grade out of Death Valley at high speed my truck will tell me to slow down a little to cool off - I'm not worried about it. It is peculiar though that this is my highest hp vehicle, and it has the smallest radiator. (The other ones likely need an overkill cooling system because they aren't smart enough to prevent damage if you just held the petal to the floor for a half hour straight).

 

Its funny that you mention this because those are all of my exact same thoughts on my 2016 HDPP. I noticed the dead spot in the steering a few times as well. I especially noticed how much it sways in crosswinds both towing and non towing. The tires were deflated a bit when I picked it up, but had pumped them to the max cold psi before my first tow trip and it still swayed and felt squishy while towing. I had traded in my 2011 Toyota Tundra crew cab short box that had E rated tires and felt that it was much more stable and handled the same load better, which I could not understand. I am thinking that the C rated tires are to blame as well.

Please let us know if you notice the difference once you switch to the E-rated tires as I might consider that upgrade as well.

 

I'm getting the new tires tomorrow afternoon and will report back after a day or two.

 

Totally interested in your findings as well.

 

New tires were installed yesterday and i have noticed an improvement in handling. I don't have the feeling I'm rocking around anymore or swaying and the ride is stiffer as noticed when you hit the bumps, as well the tires aren't squatting with some weight in the back like they were. I will post more as the weeks go on and I get to test them out some more. One thing I noticed at the tire shop was the difference in sidewall stiffness between the C and E rated tires, the C's were quite easy to bend and flex and I know it had to have an effect on ride. One thing I'm not sure about is how much air pressure to put in them, I have the heavy duty aluminum rims that from factory are supposed to be at 48 PSI with the C tires but I now have tires that will take 80 PSI so I picked 60 PSI to run in them and will let everyone know if the rims grenade on me. If someone else knows what I should or shouldn't do in respect to the PSI I would like your opinion. I would also really like to know what the thinking is from Ford as to why a HDPP truck has C rated tires when previous year trucks and even the current XL trim trucks are coming with E rated tires? I'm a little ticked off I guess that a $43,000 truck can't be outfitted properly when they had it right the first time. My advice to anyone purchasing a HDPP truck is agree on a price and then tell them you need proper tires upon delivery.

 

My 2015 and 2016 Lariat HDPP SuperCrew orders kept getting cancelled or delayed for the build, and it was a $49K truck before taxes. I found and bought a very-low mileage 2104 HDPP SuperCrew, (17" 7-lugs) and it has the factory tires; load "E" rated Goodrich Rugged Trail tires. I would have been disappointed as well to find the rating on the tires on the new builds. I did a LOT of research before ordering, and thought the factory tires were likely going to be the Goodyear Wrangler A/T Adventure with Kevlar in the 18" size with the 10-ply rating. Both of my DORA's indicated LT275/65R18C OWL All-Terrain tires. I didn't do enough research to find that the "C" didn't mean the 10-ply rating.

 

Sorry - quick question. If the hitch is only rated for 1,200 lbs then how do they get the 11,000 lb tow rating? 11,000 lbs * 13% = 1,430 lbs tongue? Or is this when the WD comes into play?
