Looking through 2010 F150 brochure (online)and GVWR and max payload of 4wd 5.4L SCrew 145WB and with max tow pkg payload is up @ 400 lbs to max of 1,910lbs and GVW is up to 7,625lbs. (157" also higher)

Why would Ford keep this secret? Perhaps they don't want to be accused of using the same magic potion Dodge did to bump their ratings without actually changing anything mechanical?


Here is chart from brochure: (2009 said gvw 7,200)
SUPERCREW 4x4
145"
4.6L 3-valve 1420 7000
5.4L 3-valve 1510 7200
5.4L 3-valve 1910(2) 7675

157"
4.6L 3-valve 1430 7150
5.4L 3-valve 1540 7350
5.4L 3-valve 1810(2) 7700

(2) indicates max tow pkg

 

Perhaps this was done as the 8,200 Heavy Duty Pkg is not coming?

 

That's what I was thinking, but shouldn't those numbers being even higher yet? Maybe, closer to 8,200? The HD package should get you more than 400 lbs.

 

But they don't have the equipment from the HD pkg. Ex: the(ugly) 17" 7 lugs wheels.

 

sounds like a supercrew with a 8' bed if the WB went up by 12"

 

wb is the same, bump came from the longer cab.

 

oh okay i reread what you said, makes more sense now, never mind :o

 

So what did they change to increase the payload?

 

Who knows? Only funtional change was brakes but that didn't affect just max tow. Sometimes they need to change nothing. Get a more looser lawyer?

So here are possibilites that we know of:
i) Nothing changed.
ii) Improved brakes added capability for payload?
iii) After killing the baby diesel they've killed plans to produce heavey duty 8,200lb GVW SCrew and this is their happy medium.
iv) They realized that GM had a payload advantage on SCrews with their max tow pkg and they had to address it and Ford loosened up their #s.
v) They realized that some of the payload ratings of the SCrews were just too low and wanted to avoid a competitor pointing this out with a massive add campaign. So they changed the #s. (can't you see Howie Long with a Plat Screw and three heaft fellow football guys and Howie telling then that one guy has to stay home as othewise they'd exceed the platinums payload rating, then gettting into a Chevy Crew) I'm not a gm fan at all, but I'm surprised they missed that...

Anything else?

 

I'll go in depth on this one, some may not like my response. The biggest issue with the new F-150 is the 9.75" rear axle. It's max load rating from all gatherable data seems to be 4,500 lbs (not trucks are showing up with 4050 lb RAWR, that's 90% of the axles weight rating). The axle tubes on the 9.75 are without a doubt the weakest part. I doubt the brakes had much to do with the weight as the expedition, if I'm not mistaken uses similar size and set up and has a GVW of 7900 lbs. The new brake system I'm sure helps with the stopping part of the GVW bump, but GM has them beat running gear / axle wise I think. GM's 9.5" SF is rated at 5,500 lbs (1K lbs more). I think this is where the GM trucks get their 4,200 or 4,300 lb rear axle rating (or 78%). I think that ford engineers are concerned with the weight capacity of the axle. While you'll always have a weak point in the drivetrain I think it's the rear axle (hence why the 7700 lb trucks before had the 10.25" rear axle). I've noticed that GM seems to have a real world payload of about 1820 lbs or more on their NHT trucks where your looking at 1000 to 1200 on a similarly equipped F-150. That does scare me and was a concern for me to look at GM when truck shopping.

All that being said, I think ford has done a great job with the F-150, but needs to revise their engine and rear axle set ups. More power and torque to keep up with Toyota (I don't see this as a huge competitor) and GM (403/417 is stout). I know that many on here will say that their trucks have plenty of power which I agree with for daily driving and grocery getting. I enjoy being able to pull 7% grades at 60 to 70 mph a load which is why GM and Toyota appeal to many (including myself). I think once the 6.2 shows up the F-150 will be the truck to own.

 

So is the 6.2 getting a bigger rear end? If you are concerned about the axle, just getting a more powerful engine won't fix that unless it comes with a different rear end.

 

So how many of these weak F150 axle have people known to fail?

 

Dealer told me rear axle max also went up.

 

I had one on my 03 F-150 fail, tubes at the pumpkin failed and started to bend. I know of a few others, mostly commercial but non were really running "over loaded" . Just pointing out why the truck has a low payload rating. Facts are facts sorry to tell ya.

 

I would like to know how much weight they would take before they do fail. If i put 2000lbs in my bed would they bend or would i have to double the figures they say. I know eberything has a toleranace built in but it would be nice to know how many % can you go over rated capacity before you have trouble.
