However, it does seem like a conflict that my GVWR minus my base curb weight equals a bigger number than what the payload/tire sticker says.

No matter how smart you are, or how good your eyes, you cannot see any difference in the front springs of a '99 SuperDuty with 4,000 pounds front GAWR vs. one with 5,200 pounds GAWR. But the springs are definitely different.
I suspect if you dig deep into the makeup of the GVWR of the max tow pkg vs. the regular tow pkg, you'll find such subtle differences. Not a difference you can point to, or even measure without some really sophisticated measuring devices. But different.

I don't know the details of the specs for the new F-150s, but way back when I had the details for '99 7.3L SuperDuty pickups. One difference you cannot see with the naked eye is the deflection rate in the springs. On the '99 F350 SRW and F-250 4x4 pickups, front leaf springs were available with 4,000, 4,400, 4,800 and 5,200 weight capacity (combined rating @ground). Those 4 sets of springs were all the same thickness, length and width. The only difference was the "stiffness" of the springs, which the engineers call the deflection rate.

As stated above there is a difference in deflection rate on the rear springs and the thickness of the springs at the pad. Interesting also the max tow has a 112 lb base rear axle curb weight increase over a non max tow 145 4x4. Source for above is the esource book for the dealers. Another thread a couple of months ago had the link. A little tidbit. The max tow has a 20:1 steering ratio while the rest are at 17:1.

How I wish I would have got the HD suspension option. Anyone have the sticker ratings for a SCrew with the HD suspension option.[/QUOTE]

To the OP,
There is no way to increase the number on the door jam sticker. However you can make it tow/haul/ease your mind somewhat by installing LT (8 or 10 ply, D or E load range) tires and airbags. You could install helper springs instead but I prefer the adjustability of airbags. I like the Firestone bags the best. Just keeping the truck level will make a huge difference on how it handles.

It really does exist as few members here own one.

To get the hd package you need to pick the 3.73 axle with limited slip. Only than can you get the hd payload package. If it does not let you pick that axle it is not available on that truck. Also the max rating is 80 present of what the truck can really handle so if you take it to the max but not over you are fine. Manufactures are required by federal law to rate a max that is only 80 percent of what the truck can do. this is what they call the safety threshold and limitations but by no means should you go over the max it is a legal liability. If you are only towing at you max 10 percent of the time like most a f 150 is just fine. Ford fleet recommends going to a 3/4 when you tow near the max more than 35 percent of the time. Good luck now here comes all the dis provers, I can't wait lol.
