Re: Towing Capacity
Most of the differences in towing capacity come from spring rates, and in some cases, stronger parts. The reason there isnt a difference in the towing limits of the F250s and 350s is they use pretty much the same parts, with slightly higher spring rates, swaybar rates, and a few other things, but the hard parts ducj as axles, horsepower, transmission, etc, are identical. The fact is that the 250 will pull as much as the 350, but youll be happier doing ti in the 350, and will do it better.
Your truck , with the 5.4, is never going to pull like a V10 or PowerStroke, supercharger or not, and there is not a lot you can do about it. Sure, you can regear, but that will kill your highway mileage, or you can add an exhaust, and a blower, and other hi-tech bolt ons, but the truth is that the 5.4 is not made to work like this, and while you may be able to tow 10,000 lbs, its going to be a slow, miserable trib until you trade that thing in for a PSD or Triton V10, which still sucks compared to the Powerstroke.
