You know, this is interesting too. I looked at the tire inflation sitcker on the "B" pillar on my truck and it says the actual payload should not exceed 2210 pounds. And this is with the 275/70-18E tires. They had a huge thread in this in the 2009 F-150 forum where some of the guys with 2009 Platinum F-150s were seeing 750 pound payloads on these stickers.

Well, GVWR and payload are relative to the people and options of the truck. The Lariat will likely have more options than a base truck, then the diesel lowers payload a little too. Least that's my guess.

Yeah and I agree. The same questions were posed in that F-150 thread and I agree with those guys in that 750 pounds of available payload in an F-150 is ridiculous. Some were saying it is all based on the tires but my tires are rated at 3640 pounds each. Weird.

Did you buy it new, if not, then anything could have happened. If so, then not sure what to say as to why it has it. Technically it shouldn't.

Really, it's nonsense. nonsense we don't really deal with here in MD, but a lot of people in other states do in the form of taxes and registration. Really, the f250/f350 were basically identical for the longest time, with different Fed Certification labels. Same brakes, axles, tires, springs, coolers engines transmissions frames
. After 05 they changed how the trucks were rated and you could get a 10,000 GVWR in an f250. Depended on a lot of options of course, but they made the trucks configure in a way that supported the GVW. Probably because it doesn't make sense to add an engine that xx lbs heavier, and more powerful and be able to haul less stuff. So in some sense there is science and engineering behind it, then on the other it is just marketing and sales. You'll never get the technically right answer, or the marketing answer. It just is what it is on the door....

The F350 rear block raises the vehicle so it can "squat" an extra two inches. The part numbers for the rear springs are the same between a F250 and F350. As an example, my F250 has the EXACT same rear suspension, same springs, same overload spring; however, it has a block under the rear spring that is approximately 2" shorter. F250 and F350 share the same springs.
Add that to the additional 2" of squat from the taller block and you have increased payload an GVWR.
See my above statement.

I should have added to my GVWR and payload post for 2005 trucks, Ford lists the curb weight difference from a 5.4L gas engine to 6.8L V10 gas engine as about 100 - 125 lbs. From 6.8L V10 to 6.0L PSD is about 500 lbs. The payload is highest on the V10 gasser, same or higher for the 5.4L gasser than PSD and the towing is the same (between 6.8L) and PSD; however the GVWR is higher on the PSD. All suspension parts being the same. So, the GVWR is approximately 200 - 400 lbs higher for the diesel, the payload is roughly 200 lbs higher for the gasser(s), the diesel engine weighs 500 - 625 lbs more than the gas engine(s) and the springs holding up all of that are the same. So, that 10,000 GVWR truck has the least amount of payload. Trying to figure it all out can take a while

I disagree, the F-250 came stock with code A rear springs (6084 lbs) while the F-350 (single rear wheel) came stock with code B rear springs (6830lbs). (thanks bdrummonds)

So, I dunno. The builders guide and my local Ford dealership show the same part for an F250 or an F350. I only asked them about model year 2005.
By the way, I believe the lower rating of the spring is without the overload and the higher is with. It's my understanding that, as an example in 2005, the springs are rated at 6100 and 7000; however, the difference is the overload spring, not the spring pack. Again, I'm using a 2005 SRW Super Duty as an example.

Interesting. I just called my local dealership and asked the parts department. He stated he needed the VIN of the vehicles, then he told me it would depend on a bunch of things like options, then he said it would depend on the axle 9.75 or 10.5. Once he got a little more frustrated with my additional questions he looked it up and said, "Hmm, the F250 and F350 have the same spring".
