F250/F350 rear leaf springs

Does anyone know FOR SURE if there is any difference between the rear leaf springs on these two trucks? I have been reading the forums and there is a large disparity amoung what people think on this topic. Some say no difference, some say there is a difference, some say that the F350 has helper srpings, some say the F250 can be ordered with the same helper springs. The 2011 SD order guide does not appear to have any rear leaf spring options.

I tow a heavy (12k) 5th wheel RV and I would like to move up to heavier rear springs from my current F250. What I don't want is simply a higher spring block with the same springs. If that is the only difference I will stick with the F250.

Cheers-

Look at triangle springs.
These are the ones I have in my truck

They can also be gotten in a 5400lb spring.

My truck with the early 99 tall blocks and these springs still sits with the *** up a little with a 15,000 lb bumper pull trailer loaded very tongue heavy. My friend used it to haul a 48' enclosed gooseneck camper/toy hauler that comes in at around 14k empty and 18k with a car in it and it sat about the same. They ride nice yet too.

thanks for the feedback...I guess I was not clear. I am interested in buying a new 2011 SD, just don't know whether to go with the F250 or F350.

thanks-

The springs will be the same. The 350 will come standard I am guessing with overloads standards while you have to order certain packages with the 250 to get them. At least this is how they have done them in the past. Get the 350 and put a good leveling kit. The 350 has taller blocks under the springs.

Overload standards? Are they "helper springs"?

That is what I am interested in. If I can get them on the F250 then that might be the way to go. I would rather have the lowest GVWR possible so it saves me money on tags/registration.
