I have a new aluminum F-150 Supercab 2WD F-150 with the 6,900# GVWR package. With just myself and a full tank of gas, the truck weighs in at 4,920 or so as equipped. This appears to leave me with about 2,000 lbs payload capacity assuming a full tank.

I'm shooting to load a cube(pallet) of brick in the back, the company tells me it weighs about 2,047 lbs. While I'm sure the truck can take that and then some, I don't want to do anything that will void the warranty. But more importantly, I know that payload is intended to be spread between the two axles, not necessarily all over the rear, so what is the weakest link in an F-150's rear axle/suspension? Is the axle stout enough for such weight easily, or is it pushing the limit? The door sticker says 3,800# Rear GAWR. I'm sure I'd be in danger of exceeding this before exceeding the GVWR.

If it makes any difference, I'm only traveling about 5 miles across town under 40mph the whole way. I know it's not good for a truck to be overloaded obviously, but I've seen trucks with well over their capacity survive to tell about it regularly, so I was curious if the limit is a "don't exceed this or your axle will break in two immediately", or "don't exceed this and think you can drive 80mph across washboards and possibly sue Ford". And for the record, the tires are load rated at something like 2,300lbs each so no worries there.

 

you'll be fine with what you're wanting to do

 

Just make sure you have less than 1/4 tank and you'll be fine.

 

My payload capacity is 1527lbs and tried 2080 lbs of tiles. And it's running great still at 17000 mileage.

 

all of my trucks have ridden on the bump stops at one time or another.

 

It will sag like mo'fo, but you'll be fine. your rear will probably sag a good 4" and you will be nose high.

 

You're not going to hurt it.

 

I wouldn't worry about hurting it. just keep in mind that you will not be able to brake as well...

I'm not sure how much this load of wood weighed but I can garuntee that my braking distance was triple what it normally is

 

Try to haul it over the axle, or slightly forward. Loading on the tail will add a lot more weight to the rear axle.

 

Had an almost 3k lb pallet in mine before I did the math and realize I was a little over the limit. Sure I was pointed at the sky the whole time but the truck still drives fine today.
