so what really makes the difference between a 6.0 F250 and F350?

Same engine, same tranny, so that leaves the weight differences.

I was reading on another forum for RV's that if you wanted to pull more just to add the F350 Springs and you're done.

Is that really it? If so, why do that vs putting Airbags in there?

 

350 has a stiffer suspension. You could acheive the same with air bags, but by changing out the leaf springs you don't have to worry about an air bag failing.

 

I have come to the conclusion that the F250 is made for only one reason. Some people don't need the "legal" GVRW of their truck to be as high as it is on the F350 and don't want to pay the extra registration costs that some municipalities charge for the higher GVRW of the F350.

 

F-350 has a higher GVWR and taller blocks in the rear. F-350 is also available as a dually, and usually shorter (higher) gears. Other than that... Not much.

Blang, maybe back in the day, but not so much anymore. I've ridden in F-350 duallies that ride smoother than my log wagon truck.

 

I know which forum you speak of Rock...you would have had the weight police in a frenzy if you asked that there.

 

Also, I don't think the F350 is available with the 6.75' bed...only the 8' bed.

 

Negative ghost rider. Dad's work owns a 2003 F-350 crew cab short bed DUALLY. Also, I've seen 08 duallys in the short bed too. SRW F-350s are also available in the short bed too.

 

Wow, that's really odd. I didn't think you could get the smaller box with the higher payload. I know on the F250, getting the shorter box decreases the payload. Weird.

 

Yep....We have two 2005 F-350 crew cab, short bed, dually trucks back home on our farm.

 

Although things may have changed in 2008-2009, it used to only be PHYSICALLY the rear blocks and the stickered rating. I''m sure there are some configuration differences, like the wide track front axle only being available with the F-350/F-450, but the 250/'350 trucks are pretty much identical. I'll say this, the additional cost up front and the additional resale value returned make the 350 upgrade a no brainer if you haul a trailer of any decent size. The ride of these two trucks are not different, either. You just sit up a bit taller and wear an F-350 smile.

 

The funny thing is, if I put airbags on my F250, I essentially increases my GVWR, however, since it is not a 350, it's not going to be spec'ed out on the door jam sticker...which I don't care about. What I am more concerned with is if I happen to trade my current 5th wheel to a larger one, I can take the pin weight. Right now I am sitting around 1900#'s and all the ones I am looking at are in the 2300 and up ratted pin weights. And technically, 2300-2800 pin weight is over weight for a F250 even though I see people doing it everyday.

 

I was looking into this the other day.Can anyone possibly tell me what size block an f-350 has in the rear vs. the 250? I installed a leveling kit on my f-250 and I heard the 350 block was taller.
I was just wondering how much taller???

 

Sounds like what I plan on doing to my truck... the F150 frame is already a beast... but speaking with certain people that do custom frame work, they can easily make my truck into a towing/hauling beast by adding leafs, better shocks, rear axle, and such.

But more importantly, once you start modifying the tires/rims and suspension system, there really isn't a manufacturer set GVWR anymore because you've modified the truck to the point in which you've essentially made it stronger than what it was before. Mainly once you start talking rear axles, say you swap from a 9.75 to say a 10.25 rear axle, you've really beefed things up.

If you think about it... it isn't that hard to do. Heck, a buddy of mine who does collision repair made his OWN tow truck. He started with a F250, and replaced the rear axle to a dual rear wheel axle with a 10.25" from a 9.75", went with airbags and heavy duty shocks, and got an aftermarket towing bed with the hydraulics and such... you can't tell it was a F250. So what is the real GVWR? He put it down as 20k at the DMV... but we know it can go higher...

 

Pretty sure the F-250 has a 2" block and the F-350 has a 4" block.

Manual, the 9.75 is a F-150 axle. F-250s (older) came with 10.25 axles and the Superduties came with 10.5 axles. The F-350 duallies came with Dana 80s, I believe.

 

No kidding....


I've had my share of crazy threads over there.
