Ok instead of me being a jacka$$ letme ask this ????? The right way. I would like to equip my 1977 f100 2wd supercab shortbed, 351m, c6, 9"
truckso that I can pull a fifthwheel/goose neck.
Understanding that there still is a downward pressure concern on the 9" housing .....
If I upgrade the rear springs - will 250 springs fit or should I use 150 springs and a helper spring kit.
From what I have found the brakes are the same as the 150, shock on this truck are power front disk. Should I convert to rear drums, upgrade to a 250 brake booster?
(If the 9" is rear the concern I have a d60 laying in the back yard.)
So with this corrected stance can you re-respond hoping to get the information I would like to have.

I don't have any facts or anything, but I'll just throw my $.02 into this...if you wanna tow with a fifth wheel, tow frequently, tow a heavy load, you really ought to just have an F250 at minimum.
That's what they were designed for.
You do what ya want....but please use your head.

Ok I can see this between the 150 & 250. but the 100 and 150 should be the same correct.

I am not 100% sure I will try this with the F100, I know this is better done with a F250, I just only have a F100 right now. I am just trying to figure out what is needed. The most I would be tugging around would be the trailer (as short as possbile 16' -20') and my 67 Bronco off road rig 2800lbs. this would prob not be more then 6000+- lbs.
Thanks agian,

they might be different. there is difference between 2wd and 4wd frame section modules, so it would make sense for there to be a difference in f100s and f150s. i dont have the numbers to make sure but someone here will. putting the dana 60 in it and upgrading the springs would help but you still would be better off with a heavier duty truck. im not saying you cant do it, but your truck wasnt desinged for it. does your truck have a fifth wheel already or do you want to put 1 on it?

I guess I will just let that one go since the guy has another bit on-line, and I will go get a 16 dovetail to pull my off-road rig, and keep looking for a F250 crewcab 4x4.

YES it is clear, you are the one being a jacka$$, I normaly do not go off on people like this on message boards because it never ends wel for anyone.
So. With that said, I repeat there is not a major diff between the f100 and f150. They use the same body, frame, motor, tranny, rear axle, front suspinsion, shocks and brake system. If there is a diff at all it might be, as stated before, a minor diff in the rear spring rate. Yet the f150 can be used to pull fifth wheel goosenecks.
With this said, I ask that if you have nothing posiive to contribute to this thread DO NOT POST.

It's too weak to pull that much, the tongue weight might reach or over what the whole truck was originally rated for. And I ask again, how do you plan to STOP this death trap? The brakes will heat and fade.
If you really want to learn about towing, check out the towing forum on here.
But it's not only you -- see IZZY's post for a great example.
Are you even thinking of other drivers on the road while you're towing a 5th wheel down the highway? Do you want to be responsible for the death of a family when the trailer lets go and plow into a minivan? Now who's the jackass?

Most trucks going down the road hauling a trailer are by law overloaded. When I bought my truck ('77 f150 Supercab), it had been modified for hauling a gooseneck. It had a gooseneck plate, rear-end was swapped for a D60(which had a dually hub conversion), and a hellwig helper spring set-up. Now that combined with the 460 swap it aparently did well (aside from the bent rear spindles). But that being said, even though it was a 3/4ish ton truck, legally it is still a F150, and only rated as such.
You seem to have answered your question now, but personally, I wouldn't do it. Mainly due to the risk of other people on the road, but also for my safety, family safety, and the load on the trailer.

The GVW is NOT the actual weight of the truck!
The GVW actually refers to this: GVWR = Gross Vehicle Weight RATING.
Rating: The actual weight of the truck, driver, any passengers and cargo should not exceed the max GVWR.
If the GVWR is 5500 lbs., the truck weighs 4400 lbs. (1977 F100 S/C I-6 shipping weight: 3950 lbs), the driver weighs 200 lbs., the amount of additional weight the truck can SAFELY carry is: 900 lbs.
A 30+ year old F100 is totally inadequate for towing anything more than 3,000 lbs. Hell, when the truck was brand new, 3,000 lbs. was about the max towing capacity.
I would not attempt towing 8,000/10,000 lbs. with anything less than a F250 Heavy Duty.
btw: The GVW is listed on the Warranty Plate or Safety Standards Certificaton Label of EVERY Ford Truck.
Y'all will see this on the Warranty Plate (or Certification Label) on every Ford vehicle: WARRANTY VOID IF MAX GWV IS EXCEEDED
