What are the differences between the F-350 and the F-450? Looking at buying a 2008 to 2012. Pull a horse trailer, going to get a dually. Thanks.

 

2008-2012, you'll get more towing capacity on an F-450.

 

I think he may be asking what mechanically seperates the two..what gives the 450 the extra capability?

-just my take, and I'm not sure I have an answer for it either.

 

I think they(f450's) have more lugs on the wheels, which beefs up the tow capacity/strength. Stronger/stiffer frame, would also make sense... What is the GVW of the horse trailer? Different gear ratio options.

 

The 450 will have different axles, brakes suspension etc... I believe that the frame of the factory 450 with truck bed (not cab chassis) is actually from a 350. The cabs will be the same. In general the engine and tranny are the same, but different programming. 450/550 engines are often derated versions of the ones used in the 250/350. Due to the gearing and weight, the 450/550 are significantly slower, both in acceleration and top speed.

 

At some point after the 08 F450 the rims became f350 size instead of the 19.5 previous.

 

2008-2010 F-450 pickups had the 19.5 rims, with the larger brake rotors that fit inside of them.

2011-2014 F-450 pickups have the 17" rims, like the F-350 duallys.

2015 F-450 pickups will return to the 19.5 rims, with the larger brake rotors that fit inside of them.

F-450 pickups produced by Ford, of any year, do not share the same frame as the F-450 chassis cabs.

 

Thanks guys. Yes Fellenz I was just wondering what makes it a 450. I know the only difference in a F-250 and a F-350 is a extra leaf spring. So what mechanically makes a F-450? Larger wheels, different gears?

 

Truculent what didn't you like about the 08 F-450? What where the problems you where having?

 

Assuming the 6.4 motor based on his similar words to his 6.0. Total speculation.

 

Loved the truck hated the 6.4L. Mine was a DPF and totally unsuited for metro area driving. Regen cycles would dump diesel into the oil. Put 15 qts in on a oil change and get 17 qts out! Also had radiator probs and EGR probs. When it would clean the DPF my "power" would drop way down and sometimes it wouldn't get up hills hauling loads. Had stock 4.30 axles.

 

Not sure why but It will not allow me to post photos even though I am a paid member. Shot me an email and I will send you a photo of my 2011 F450. I have owned a bunch of 350's and have Loved my 450, why. 4x4. Great combo

Crawl under an '08-'10 F450 and look at rear axle. Crawl under F350 other model year F450 and look at axle. That's all ahm gunna say about that.

 

The '08-'10 F450 will have the wide track front end, I believe it's called a Dana Super 60 axle. The F350's also have the Super 60 but 450 has beefier parts inside the axle. Also I have seen some F450 pickups that were optioned with the 7000lb rated front axle thus the reason the the upgraded inner parts. All frames are the same for the 250, 350 and 450. The frames are different when you get to the cab and chassis. The rear axle will have 10 lugs and the '08 will have 19.5 wheels and tires, at some point during '09 Ford discontinued the 19.5 and went with 17" wheels and tires. Rear axle brakes are much larger and I think the rear axle is the same Dana 80 that's in the F350 duallies with a few upgrades. A F450 will have either 4:30 or 4:88 gears.
The F450 with 4:30 gears will have a GCWR of 29,000lbs
The F450 with 4:88 gears will have a GCWR of 33,000lbs.
The F350 duallie will have a GVWR of 13,000lbs
The F450 will have a GVWR of 14,500lbs.
The F250-450 have the same horsepower ratings and torque ratings, it only changes in the cab and chassis models.
Thats all I can think of off the top of my head.

 

Rear axle in '08-'10 F450 pickup is a Dana 110.

Super 60 (widetrack) front axle for the F350 was an option as I recall and not factory standard. I've yet to see one on the road. My 450 will turn circles around most pickups. It out turned my Excursion no problem.

I "think" they did away with the 29/33k gear ratio dependent rating in '09(?) and just made it a flat 33K. No idea why since nothing changed in the truck.
