Difference in Susp btw 2007 F250 & F350

While I do appreciate your response I do not understand where your referencing of "guessing" comes from. I asked my question to find out the difference between the suspensions of the F250 and F350 (if any) and ratings if applicable not the rating of the F250 vehicle.

You can accept that and be certain you are operating safely or ignore it and do anything you like as many here on this forum frequently extoll.

You are asking people who neither designed the system (it is an engineered system, not the sum of it's parts)or forged the parts it is constructed of, therefore the responses are based on their experience, part numbers, etc and anything except what can be supported by the engineering teams data that created it. In my estimation that leaves it a "guess" at best.

OK so bad example there. I totally agree with previous poster about other factors. Driving recklessly, tired, drunk, ...

As far as the differences between an F250 and F350, I don't believe there are ANY differences other than rear suspension in 2007. The 350s came with a 4" block and an overload spring, whereas the 250s had a 2" block. The overload spring could be had on a 250 if the camper package was ordered.

Hey I can understand and appreciate that because I like road safety just as much as the next person driving down the road. The reality is there are many who tow within the ratings and there are those who tow outside the rating. Smart responses, flaming and sarcasm probably won't stop those who overload. Maybe tow charts, statistics, and experiences given in an honest and concerned manner might be more moving to those we are trying to enlighten.

One thing I would like to offer is that overloading is one of many negative risk factors. When do we talk about texting/cell phone handling, improper tires/inflation, worn brakes, unsafe speed, insufficient rest, proper diet/hydration, medication (sedation), etc.?

I can see from a few of my responses that some are so hypersensitive that any question of ratings will lead some to imagining I am trying to use a Pruis to tow a 40' triple axle travel trailer (humor).

Like I said before I really do appreciate hearing from all sides of the fence but I was honestly just asking the mechanical differences of a F250 and F350 just for my curiosity in how Ford builds and markets pick up trucks. I tow with my Excursion but was involved in a project vehicle F250 that used F350 as parts donor (non suspension) and saw way more similarities than differences and wondered about the suspension. It is interesting to note in the 6.0L owner's supplement that both are rated to tow the same weight trailer because they both have a GCWR of 23,000. I am now just wondering what is the difference in their cargo ratings.

No on to your good idea question my answer would depend on the ratings of the tow vehicle and their relation to the weight of the boat/trailer. The exhaust tip appears to be one for a diesel and off the top of my head I thought those trucks can tow 12K-15K bumper pull and I can't see that boat weighing more than that but my eyes aren't as accurate as a CAT scale lol!

I think many of us are worried about all those people that are of the opinion that if you CAN do it you SHOULD do it. We do share the road with them.

Any car or truck can tow more than what it is rated for. The rating is for safety reasons. Some people argue that the ratings are for marketing reasons and still safe.

Does this look like a good idea?

In addition to the overload springs and 4" block which are standard on the 350, you require the 18" or 20" tires to get the 10,000+ GVWR.

I just wanted to know the mechanical differences between the two trucks including their tow/haul ratings not really understanding what you are referring to with the legalities?

I heard/read somewhere that the F250 and F350 have the same driveline components, brakes and sometimes even springs. Is this true?

If the springs are the same what is different about the suspension that they rate the F250 to haul less than a F350 or are they rated to haul the same?

Thanks

You are right, but it comes down to legalities.

Ok I think I see what you are talking about. The helper spring is the single leaf that is mounted above the spring pack that contacts that mount/perch on the frame? So F250's (2007) have a shorter block and don't have the helper spring then?

A F350 has an extra separate helper spring plus the multi leaf spring. Pretty sure the multi leaf spring is the same on both trucks. A F250 with the "Camper Package" has this extra spring plus a rear sway bar.
