What is a F550 ?


Recommended Posts

You cannot make any implications based on a name badge these days. You MUST look at the specs on a specific truck and then make decisions. For towing this is critical. The equipment is very important. Axle ratio, rear axle rating, and tire ratings all are important factors and in general are not as closely related to the badging as they once were.

OK, I realize all that is being said but back in the old days the F350 was a 1 ton and all I'm asking is was a F550 a 2 ton or what?

Many people have asked about my F550 and all I can say is I think the F450 is maybe a 1-1/2 and a F550 is a 2 ton but maybe it should be a 1-1/4 and 1-1/2.

The "Class" rating is weight related and intended for calculating commercial vehicle taxes, shouldn't be used for anything else.





In the United States, commercial truck classification is determined based on the vehicle's gross vehicle weight rating (GVWR). The classes range from 1–8.[2][3] Trucks are also classified more broadly by the Department of Transportation's Federal Highway Administration (FHWA), which groups classes 1–3 as light duty, 4–6 as medium duty, and 7–8 as heavy duty.[2][4][5][6] The United States Environmental Protection Agency has a separate system of emissions classifications for trucks.[2][7] The United States Census Bureau also assigned classifications in its now-discontinued Vehicle Inventory and Use Survey (TIUS) (formerly Truck Inventory and Use Survey (TIUS)).[8]


More detail at the link but you really should just ignore this for the most part. Maybe, if you are converting a HDT it might matter?

Hi, they have been and can be refered to as a 2 ton (medium duty), but as everyone is saying the vehicles independant SPECS are most important. At least thats what I was told by my builder.
