The Aluminum body lighten it 1900 pounds?

No, 700lbs. But what else on the truck changed? Frame? Engine/trans Cooling? Suspension? Brakes? I don't know. Obviously the way ford sets tow ratings felt the new design was better somehow.

Fairy Dust?

250/2500 and 350/3500 are not truck classes, they are just model numbers and their capabilities can mean anything the manufacturer want them to.


I also think many put too much weight on this J2807 thing. It is just a standard set of tests to come up with a tow rating. It does not mean that a J2807 truck will outperform a non J2807 truck with the same load. It also does not mean that a higher J2807 truck can outperform another truck with a lower J2807 rating. For example, look at the 2.7 Ecoboost and 3.0 Ecodiesel as an example. The 3.0 Ecodiesel is J2807 rated per Ram to tow more than the J2807 rated 2.7 Ecoboost yet the 2.7 Ecoboost has been shown numerous times that it will out perform the 3.0 Ecodiesel loaded or unloaded by a considerable margin.

It also doesn't mean that any manufacturer is fluffing their non J2807 numbers either. For example, a 2011-2014 F150 Crew Cab 3.5L Ecoboost 3.55 was only rated to tow 10,000 lbs before J2807. Now the same truck is J2807 rated to tow 11,900 lbs in 2015. So how is the non-J2807 rating fluff when it is 1,900 lbs less than the J2807 rating?

I always got the impression that the towing 'standard' was a bunch of 'specs' the marketing guys came up and everybody said we can live with that,The SAE just rubber stamped it.
Engineers don't talk specs like that ,but advertising does.

An SAE spec means something meets or exceeds a certain minimum specification, same as your engine oil. I don't think engineers really care what manufacturers or advertisers do with it.

If Ford's F250/350 trucks could meet the SAE standards with the ratings they claim don't you think they would say they do?

2017 Ford HD's will no doubt meet the SAE standards they post. And WILL pass the tail gate "twist test".;)

At least we know now this thread was started soley as a kool aid fueled attempt to disparage Ford. Start a thread, let a few replies come in and then let your motives be known.
