It looks to me as if you do indeed have the heavy duty tow package. To be 100% certain you should check the axle (Rear). See if you have a Sterling 10.5" or the Dana M275. If it is the Dana your truck is essentially identical to an F350 (As far as I know) and should have the higher RAWR. If it has the stirling I am not sure what is going on. You have the lighter front springs (5200 Lbs.) which reduce your overall axle capacity.....But that shouldn't affect it as much as the rear. You can always change those to either the 5600 or 6000 Lb. front springs......But I wouldn't go there yet.

Check your axle. If it is the Dana....Get the truck fully loaded and go weigh it and then just the rear axle weight. Then, hook up the trailer and get the truck alone with the trailer hooked up, the rear axle weight again and the entire rig. Subtract the entire weight of the truck from the first measurement to the entire weight of the rig n the second measurement and you will have your loaded trailer weight. That should be under 15,400 when you factor in the SxS (Or weigh it with the SxS).

Then, check the difference between the rear axle weight with the trailer on vs. off. That is your pin weight. If you get those weights and you know what axle is under there you will know how close you are. Like i said....It is basically impossible for you to stay under your cargo weight. However, if you have the Dana axle and the spring (HD Tow package) then it is just a de-rated 350 and you can use 11,500 as your GVWR for the truck....BUT...that does not make it legal as your yellow sticker only allows you 10,000 Lbs.

Also, check the gross weight rating for your tires. You do not want to exceed that for your loaded (Trailer hooked up) RAW on the scale. You are going to be close. But I wouldn't panic until you know the facts. Lot's of people tow over weight (Doesn't make it right) but these trucks have a pretty good margin of error (For example, the M275 shows over 9000 Lb. capacity on the Dana website (So I've been told) and yet only 7230 on an F350 (or HD 250). The tires become the limiting factor and they can be changed if needed. There is room. It depends on your needed level of comfort and if you are willing to get a ticket and be inconvenienced if you get stopped (Unlikely). Check the Axle, then get the weights. Then you'll know. Good luck!!

 

Yes, you do have the overload spring. As I Mentioned before, GVWR/GCVWR are numbers that are somewhat of a gray area. It's the GAWR's both front and rear that you must not exceed. You will only know that by hitting the scales.

 

Found a thread on the "high capacity trailer tow package" and screenshoted the details. A few comments below it does confirm that the Dana axle is being used instead of the sterling.

 

Something is wrong. Max front springs are 6000 LB. 5200 is the lowest spring rate. Also, what tires are on yours? Can you post your window sticker? Are you by chance a Canadian truck?

 

Here's a WAG for you as to what is going on:

Was your truck built in the early fall? Did you buy it off the lot?

There was an entire group of vehicles that were produced with the WRONG stickers. There is a whole thread about it on the '17 forum. If your truck was produced before November i'll bet that is what is going on here. If you post your window sticker or just give me your VIN I can check very quickly for you. These "Stickers in error" had the wrong axle weights on the trucks. The Cargo weights were correct and you will be over....But, based on what you are telling me your GRAW should be 7230 and your GFAW should be 6000.

 

He's got a 10/16 build date. He posted a photo of the VIN decal early in the thread.

 

Right. I forgot. I think the sticker is wrong.

 

Wouldn't Ford come up with a corrected sticker for him?

 

Just took a picture of my sticker. That would alleviate a little confusion if some of these numbers were wrong.

 

Well, to be sure, if the sticker is wrong, the only thing that will change are the Front and Rear GAWR numbers. Because you have the 10K option, the stickered payload capacity will not change. You would still want to go over the scales to be sure you are not overloading the axle weight ratings.

 

I would ask your dealer to contact their regional rep. People who had stickers affected are getting new ones. You should have max front springs and the Dana axle. You probably do but your sticker reads otherwise.

New stickers will NOT change your 10,000 GVWR on your truck. They also will not change your Cargo capacity. They WILL however , combined with looking at your tires' load capacity, tell you what your axles are capable of and, after properly weighing your load you will be able to decide if you can live with being over on cargo capacity (Your truck is essentially identical to an F350 which has an 11,500 Lb capacity) so 1500 Lbs. more than your yellow sticker.

As long as you are not over on the axles I personally wouldn't worry about it.

 

LOL...We must have been typing at the same time.....

 

Only the SRW 350's had the misprinted stickers reported in my stickergate thread but that front GAWR is odd on an HD 250. The rear GAWR is derated just like the GVWR on the HD 250's. So despite it being listed as 6340#, it's the same axle as the SRW 350 and shares it's rating. However, the real weak link is that the truck is optioned with the 65 series AS 18" tires (275/65/18) which have a lower rating than the 70 series AT 18's (275/70/18) or the 20 inch option. They are only rated to 3415# which limits your true RAWR to 6830#. I'd upgrade to an AT tire in the OE 70 series size if coming up short. That would net a 7280# capacity...

 

From everything I've read in this thread, I agree. The 275/70/18's will give you all the towing/load capacity your truck can safely provide. Which is a lot more than your sticker indicates.

 

the question then becomes how are the 3.31 gears going to affect it...It wont tow as well as with the 3.55's though it will nicer when your not towing...
