F450 vs. F350 Differences

[NM F250Guy]

I'm looking to get a new dually F450, but was curious about the big difference in 5er tow ratings between it and F350. Is it just the rear springs that give it the higher tow ratings? That's what salesman told me at a dealer today. Are there really no other differences in these? Any help is appreciated. Thanks!

Tires, wheels, brakes, frame, axles, and suspension. And therefore GAWR, GVWR, and GCWR. About the only things that are the same are cab, engine, and transmission.

                          F-350 DRW           F-450 pickup
Tires,                     245/75R17             225/70R19.5                
wheels,             17”x6.5”, 8 on 170mm   19.5”x6” , 8 on 200mm
brakes, front        13.66”                     14,53”
brakes, rear         13.39”                     15.35”            
frame thickness*    2.80”                      3.20”
front axle              6,000#                   7,000#
rear axle              Dana 80, 9,750#    Dana S-110 12,000#
front suspension    6,000#                    7,000#
rear suspension     9,750#                  12,000#

And therefore 

Front GAWR,           6,000#                     7,000#
Rear GAWR             9,750#                    12,000#
GVWR                   13,000#                 14,500# pickup, 16,000# chassis cab
Max GCWR            26,000#                   33,000#

* - chassis cab. I’m not sure about DRW pickups

Thanks, I figured he was just trying to sell me the last '08 350 dually on the lot. I'm surprised that the frame is different! I assume beefier. I plan to get a 5er that exceeds the tow rating of the 350, so was curious about the differences.

get the F450 I love how my pulls my fifth wheel.

If you need the higher towing capacity the F450 is an awesome vehicle! I have owned mine for 13 months and pull a Teton fiver and it performs great.

F450 vs. F350 Differences?

Biggest difference that I can think of is the size of the smile on my face... MUCH bigger when driving my F-450 than it was when I drove my F-350.
