Being new to Ford's, what is the big difference between the F250 and the F350?

08-31-2002, 03:33 PM
I've been to two dealers and both salesmen really didn't know what they were talking about. Every time I asked a question they had to look the answer up in a book or ask somebody else for the answer. I appreciate all your replies and thank you in advance.

Find a Ford Truck dealer. Not a car dealer that has a few trucks on the lot. Even if you have to drive farther it will be worth it. There are three dealers here but only one has a large stock on the lot and knowledgable salesmen. Find one and you will be happy.

Can't give you specifics since I'm a Dodge man, but I can tell you get the 350 if you're buying. It'll have a heavier payload, as well as should have heavier brakes & suspension. I'm sure Brickman Lawns will chime in as he knows a lot about Ford. Several others also.

heavier payload in the bed, brakes and suspension is beefed up. Basically that's it.

Randy I guess I am getting a reputation. :D

I am not trying to argue with you guys, but if my FORD 2002 truck specifications books can be believed there is no pay load difference. The GVWR is the same for both trucks, 20,000 lbs. I regularly run over that. In fact on the spec sheet the two are listed as F 250/F350. Also they use the same Dana 80 axle. And the Dana 60 in the front. I have parked my F 250 Off Road beside a F 350 and looked at the suspension and counted the springs. I cannot tell a difference. I have seen one spring less on the F 250 with out the Off Road package. The brakes may be bigger, I don't know.
I know there used to be a difference between the two, but with the F Super Duty series there doesn't seem to be a noticable difference. With the 350 you can get a dually, but it isn't until the F 450 the payload increases.

Dunno Hoops if this helps you or not. But you are right about the dealers not knowing much about such stuff. They are selling trucks at a car dealer lot and as such don't know what is going on.

Here is what is silly. The F 450 and F 550 are rated the same as well unless you get the High Capacity Trailer Tow Package on the 550. Then the F 550 is rated for 30K instead of 26K.

Brickman Lawn Care -"The GVWR is the same for both trucks, 20,000 lbs. I regularly run over that. "

Brickman, that is quite a heavy duty truck you have there. ;) I think you mean Gross Combined Weight Rating for the 20,000 lbs, not Gross Vehicle Weight Rating. The GVW rating should be in the 10-11,000 lb range for the F-350 if my memory serves me right.


09-02-2002, 12:16 AM
I see what you are getting at, and after some more looking found the payload specs for what Hoops was looking for. These are all Ford recommended max payloads in pounds. These are for regular cab, the numbers change some for extended and crew cabs. Also depending on the wheel base the numbers are a little different.

F 250 Single Rear Wheel 4x2 - 3440
4x4 - 2940

F 350 Single Rear Wheel 4x2 - 4410
4x4 - 4045

F 350 Dual Rear Wheel 4x2 - 5455
4x4 - 5045

On the F 350 Dually Crew Cab the max recommended payload is 800 lbs LESS than shown above. Gross vehicle weight rating is 11,500. The combined vehicle weight rating is what stays at 20,000 for both the 250 and 350. Pottstim you are right, the GVWR is 11,500 for the F 350 dually. Only 8800 for the F 250. I cannot see what the dif is, here again the only thing I am seeing is the dually is rated for more. I guess the two extra tires is where is comes in at. I am unable to find a change in the axle until you hit the F 450/550. It is AMAZING what this book has in it. Brake size, axle capacities for all the trucks listed, gear ratios for all trans, etc.

I spent a lot more time looking thru the book, the brakes do not change in size and brake pad contact area until you hit the F 450/550. The 250 and 350 stay the same in that area.

Dang, now I know that I know more than most Ford TRAINED sales people. And the book is there for them to look at, the same as it was for me to pick up off of their brochure rack.

I hope this helps, let me know if you have any more questions.

Here's something else to chew on:

I pulled my '01 F-350 SRW next to my '02 F-550 to see what my $4000 additional got me, it wasn't much.

The frame rails are identical with the same stampings. I don't have a micrometer to measure the gauge of each, but if they're different, it's not by much.

Both trucks share the same front axle, which is also used in the F-250. The 550 has lower gears and bigger brakes, along with the 19.5 wheels and tires. The axle housings and steering components are the same, with identical casting numbers on them. The only exception is the passenger side tie rod end, for what reason I don't know.

Now we move to the rear end. Here's where the big difference is. My 550's rear is HUGE! About twice the size of the 350's. It also has 4.88 gears, bigger brakes and again, the 19.5 wheels & tires.

The point here is you're getting an awfully heavy duty front end on the 250, and the rear is the same as the 350 SRW with the higher weight rating. If I knew then what I know now...
My 350 cost me $1500 over the 250

09-02-2002, 12:54 AM
That will make me feel much better every time I hook up to my car hauler and over load Fords recommended weights.
Now that you meantion the F 550 rear end, the spec book I have says that the F 550 has about 3 inches MORE brake contact area on the back axle than the other trucks.

09-02-2002, 01:07 AM
I was stunned at what I thought I was seeing at first with the front axle. I literally crawled underneath with a pencil and wrote down numbers to compare. They're the same!!!

09-02-2002, 10:33 AM
my buddy got a 450 a year and half ago and he did his home work and found that the 450 and 550 are basically the same the only difference is that the 550 has one more leaf spring in the rear.Now that is what he told me he wrote down parts numbers and all that .So he said why get the 550 and pay more while the 450 did what he needed. only carries just a little less but you can always put in a leaf .May not be legal but as far as spec to spec it works.

The benefit of the 550 is that rear axle with the 13.5" ring gear in it you would be hard pressed to bend(axle) that sucker with a load. I have used a 550 a couple times and these trucks are good but they handle and ride like a MDT it rides smoother than my F-Superduty (450) but it sure doesn't handle like my F-Superduty. These trucks are heavy I really had to put my foot into it to get the sucker moving but I blame most of it on the rotten automatic tranny the PSD has enough power.

I wish a 450 or 550 would fill my needs but they won't just don't carry enough weight :(

09-02-2002, 12:19 PM
Go with a F 650 Super Crewzer. That would handle a lot of weight and give you a plush ride. Leather seats, push button automatic. :D

Herein lies the problem. Although the trucks appear identical, all DOT is concerned with is the tag on the door post. I guess what we're paying for is the ability to haul a liitle more payload legally.

Thanks Pelican, Brickman. I built an F250 and F350 the way I want it on the autobytel.com site and the price difference was only about $400. I went to the dealer yesterday and they had an F250 and F350 sitting side by side and the only difference I saw was that the 350 sat up higher. Not being a mechanic, I crawled under each one to see if I could see a difference and I couldn't.

Based on your responses and the fact that the price dif is minimal, I think I'll go with the 350 V10 4.3 axle. You guys have been a great help!!



09-02-2002, 03:26 PM
The V 10 is a great engine, but I think in the long run you would be happier with a PS and 3.73 rears. What ever you go with I know you will like your new truck. I have had mine now for 2 years ( man time flies when you don't have a clue :D ) I bought it Friday before Labor Day 2000. It now has 112K miles and runs just as good as it did with 18 miles on it when I drove it off the lot.

09-02-2002, 04:24 PM
I wanted the PS but I'm getting a Crew Cab and want to hang a plow on it. I've been told that nobody will hang a plow on the Crew Cab because of the weight.

You're right though, this will be my first Ford and I think I'll be very happy with it. I'm going to order it sometime in the next 2 weeks (I hope). It will be hard waiting for it to come in!


09-02-2002, 05:22 PM
Because of the fact that the same front axle is used in the F 250 thru F 550 I would not be scared to hand a plow on a truck with the PS. If you can't get some body to do it for you, do it your self. I have overloaded every pickup I have owned and gotten away with it. I don't think it is the best thing to do, but some times you have no choice. Any idea what the weight difference with a V 10 or the PS? I can't imagine it would be more than 500 lbs. But I could be wrong. A good way to tell is go to your Ford dealer and find out what the shipping weight is for a V 10 and the PS. Make sure both trucks are as close to same as possible.

09-02-2002, 07:36 PM
so basicly the answer to the question is.... none of you know:)

09-02-2002, 10:43 PM
If the frames and drivetrains are the same as some can attest then the only difference could be in suspension. Right??? Well the weight rating does make a difference legally.

Now if all is the same and one can mount a plow on a 450/550 with a PSD in any frame length then why not be able to mount one on the Crew Cab or extended cab 250/350? The front suspension, steering and drivetrain are not a concern IMO. I don't think the frame will bend either. Not sure why you are told not to by some dealers and others specs plow package with an extended cab PSD like the one I hung a Fisher on. I do know that they handle the plow without a problem.

I would by the PSD mount the plow and not worry about it. If something drastic was to fail (this would surprise me) buzz the plow mount off and take the truck in. A The dealer would never know. My dealer did not even care. He would do work on my truck with the plow on and Ford would warranty it. Again you need to find a truck dealer not a car dealer with a few trucks on the lot.

Your point is?????

09-03-2002, 12:28 AM
CTFireman's right. The only place you should have any concern about this is with your dealer in warrantying repairs, and with the DOT in being over your axle weight. It's very rare for a front axle to fail unless it's been run with no oil, and I've yet to see a DOT man willing to crawl under a dripping truck in a storm.

The components will handle the load, get whichever engine works best for you.

I'm getting dizzy chasing all these threads!:dizzy:

Pelican I am just starting to have fun. :D :D I have had little better to do today (Labor Day) than to post on LS.

Oh wait, sleep, watch an adult movie, sleep, watch other movies, sleep, put a winch on my car hauler, mount some lights for night loading and unloading, try to put air helper springs on my truck, that didn't work at all because of the bolt in goose neck hitch. And now it is sleep time again. :D

09-03-2002, 09:44 AM
Thanks for all the advice. I think I have all the info I need to order the truck that will suit my needs. I've been a GMC guy for 30yrs, this will be my first Ford, I'm looking forward to getting the new truck.

09-03-2002, 04:44 PM
Well get ready to smile....

cause thats all you're gonna be doing, going from a GMC to a Ford truck.

And I'll put in one more vote for the diesel, if you want to pull anything, go PSD. I have one in my dump, and I take it out for a ride every Sunday just cause I can't get enough of that deep purr and turbo swirl. :D
